THOMAS GREENISH. LONDON: 20, NEW STREET, DORSET SQUARE, N.W. 1860. ADDRESS. In submitting the following Catalogue of warranted Photographic Apparatus, of pure chemicals, and of all necessary appliances connected with the art of Photography, Mr. Greenish wishes it to be distinctly understood, by all who may favour him with their patronage, that he will not only advise as to the most fitting form of Apparatus suitable to each practitioner’s require- ments, whether for the room, or for out-door work; for the amateur or professional; for home or foreign climes but he will also thoroughly instruct the purchaser in the use and arrangement of all apparatus purchased at his establishment. In every case, the instruction will be complete, enabling the operator to appreciate exactly what his apparatus will do, and how it can best be done. Mr. Greenish will himself superintend such tuition ; and is warranted, by the experience of many years as a practical photo- grapher, in stating, that the most thorough instruction shall be given, and the exact capabilities of every apparatus explained and proved. Where foreign use is intended, and wherever a thorough knowledge of Landscape Photography is essential, a day’s instruction will be given in the field, explaining, at the same time, the arrangement of Tents, disposition of light, etc. The value of such training cannot be over-estimated. *It will prove the fitness, and make the experimenter acquainted with the use, of every part of the apparatus; and will afford a practical acquaintance with matters of detail, which no theo- retical or book knowledge, however precise or complete, could supply at the time of need. 6 ADDRESS. Mr. Greenish has much pleasure in appending to this Catalogue certain practical information as to the management of the whole process of taking a Photograph by the only method now generally employed ; viz., the Collodion process, which allows an unlimited number of prints on paper to be taken from a single negative on glass. He thoroughly believes, that simplicity in the details of manipulation is the forerunner to the most satisfactory results ; and that, when the exact meaning of every part of the process indicated thus simply is thoroughly understood, the best possible foundation will be laid for advancement in the pursuit of the useful and fasci- nating art of Photography, equally suitable and delightful as it is both to ladies and gentlemen, whether in town or country; to the highest intelligence, and persons unacquainted with science, but possessing moderate abilities, and a fair share of industry. 20, New Street , Dorset Square , N.W.

Those about to commence the delightful study of Photography, greatly feel the want of concise, yet thoroughly intelligible, directions for their guidance. It is with the view of supplying this want, that I am induced to put into a connected form the following observations, which, for the most part, represent in- structions I have been repeatedly called on to write for the guidance of amateurs, who have vainly puzzled over scientific treatises on the subject. 8 T.

I have, in my experience, extending now over several years, in- variably found, that those to whom I have given personal in- struction in the glass-room, and who had so attained a moderate degree of skill (which, under these circumstances, is not difficult), were the most proficient in after-manipulation. In my opinion, where practicable, this instruction should be given with the same apparatus that the amateur proposes continuing to employ. And further, the plan which I have found most successful with ama- teurs, to teach them the uses of the various chemicals required, is to iodize, in their presence, the collodion with which they practise ; to make the bath, mix the developing solutions, and solution of hypo-sulphite of soda ; and with these, to which their 20, NEW STREET, DORSET SQUARE, N.W. 9 T.

Then to leave them, with occasional superintendence, to work alone for an hour or two, so that they may acquire confidence in themselves, and dexterity in mani- pulation. I have found, that this method of procedure saves valuable time, and prevents that disappointment so often expe- rienced by those who purchase apparatus and chemicals, without a previous and exact knowledge of the manipulation requisite to produce satisfactory results. The whole process is so simple in its details, that, when properly taught, and with chemicals in good condition, success must be the result. If there is one part of Photography that more than another is liable to be misunderstood, and, on this account, is the most 10 T. GREENISH, SUPERIOR SLIDING-BODY CAMERAS.

Let your written instructions on this head be as precise as you will, yet they are never sufficient. It is so difficult for anyone not fully alive to its importance, to comprehend clearly the absolute necessity of the total exclusion of white light from this room, when once the plate is in the bath, until the development is completed, and that 20, NEW STREET, DORSET SQUARE, N.W. 11 STEREOSCOPIC CAMERAS. £ s. d.

Having previously covered over the yellow calico, let the room be care- fully examined from the inside, and if it is not, under those cir- cumstances, absolutely dark , it is not in a condition sufficiently secure for the purposes of Photography. The inside of the dark- room should be blackened ; lampblack and size, mixed, will do very well for this purpose. Next in importance, as a source of failure, is want of cleanliness ; what I mean is, that although 12 T. GREENISH, PRINTING FRAMES OF IMPROVED PATTERN.

The consequences may be anticipated ; and it is not un- frequently the case, that, from the glasses having been wiped with the wrong cloth, even the bath is injured or entirely spoiled. This danger is most likely to occur at the close of a day’s prac- tice, when the cloths, bottles, etc., are jumbled together without any care or discrimination. There are many who will take great care in their arrangements when commencing work, but very few who will take the same trouble at the close, even when the day has been successful; much less will any care be taken when the day has been one of disappointment only. I recommend that the glass-cloths be white , and washed with water into which a little soda only has been put ; soap must on no account be used. Two of those, with an old silk handkerchief for polishing the glasses, will be sufficient ; also one or two coloured cloths, for wiping the hands after the finishing of each picture. When in the field, one or two more coloured ones will be necessary, or, at 20, NEW STREET, DORSET SQUARE, N.W. 13 BOXES FOR CLASS PLATES. Fig. 8.

I would here take the opportunity of observ- ing that all the Lenses sent out by me have my name engraven on the brass work, a guarantee that each has been subjected to a rigid examination, has been carefully tested and is warranted to be equal to anything that can be required of it. The Camera also and other Apparatus are made under my immediate super- intendance, with well seasoned wood, and with all the recent improvements, paying especial attention to thorough efficiency. With these preliminary observations, I will commence the manipulation, and proceed in detail through every part of the process ; I would here again urge strongly the necessity of practical instruction. A day spent for this purpose in the Jield is of more practical value than any amount of information from books, or even instruction in a Glass Room. 10 T.

In addition to great purity, a definite strength is of great importance, and it will soon be seen in the practical manipulation suggested, whether the Apparatus is equal to the work required, and also the Chemicals in a good condition, both of which may be readily perceived by the results. Let the edges of your glass be ground, it prevents their cutting the fingers and cloths, and also prevents the contraction of the film of Collodion, so as to enable you to well wash the picture after the application of the Hyposulphite of Soda.

When, as is often the case, a room for develop- ment cannot be obtained, no difficulty need be experienced with such a Tent as this; it is easily and quickly put up, and soon taken down again.

Collodion should be brilliantly polished ; and a little extra care is here well bestowed, for the resulting picture will owe much of its value to it. When breathed on, the moisture should fly off evenly and not in streaks. The glass-cloths must be washed with soda only, not soap, and be kept scrupulously clean for wiping the glasses: The silk handkerchiefs best adapted for the purpose, are yellowish white and known as China silk. Note.— Any old Collodion may be used instead of the cyanide and Tripoli, when the plates will not require subsequent washing. IODIZED COLLODION. Take one part by measure of the iodizing solution, and add to it three parts by measure of the collodion ; pour it into the “ Iodized collodion” bottle for use. A graduated measure should be kept for this purpose alone. COATING THE PLATE. — Having iodized the collodion according to the directions given, (if convenient, at least twelve hours before it is required for use,) remove all dried particles of collodion from the neck of the bottle. Then holding the plate quite horizontally by one corner between the thumb and finger of the left hand, pour on the centre of the polished surface as much of the iodized collodion as the plate will hold, or until the circle formed by the collodion just touches the edges, incline the plate so that it may run into each corner in succession, by (but not touching) the thumb first, and finally pour off the excess into the bottle at the right-hand corner, nearest the body ; and 20 T.

From this time, until the picture is finished, by the application of hypo., the plate must not be brought into contact with any light excepting that which is yellow. When once the plate is in the bath, the absence of white light must be insisted on, unless the bath be covered. A very small amount, although not striking directly on the plate, yet becoming diffused in the room, materially interferes with the sensitiveness of the collodion plate, both before exposure and while being 22 T. GREENISH, GREENISH’S NEGATIVE COLLODION. The Negative Collodion is made by Mr. Greenish, in his own laboratory. From his intimate acquaintance with the requirements of every department of the art, he is enabled to offer an article with which he challenges competition. By a judicious combination of the iodizing com- pounds in the best proportions, he produces Iodized Collodion, which, he believes, will fully justify him in stating, that its cleanliness and rapidity, without the loss of any of the delicate half-tones, will specially recom- mend it for Portraiture; whilst the absence of all tendency to solariza- tion adapts it equally for Landscape; and the vigour and detail by which it is characterized, render it a valuable acquisition in the copying of Paintings in Oil and Water-colour Drawings. These qualities, together with the property it has of keeping good for an unusually long period, fully entitle it to a high position in the estimation of the Professional as well as the Amateur Photographer. For warm climates it is espe- cially suited. In India it has already acquired a name; and in China, and also the Colonies, it is extensively employed, with the same con- stant unvarying success. Some of the finest productions which grace the walls of the Photographic Exhibition, are taken with this Collodion. developed, without sensibly blackening the plate, as a ray of light impinging directly on it would instantly do. The plate once in the bath, and the cover placed on it care- fully, wipe out the collodion-slide, especially its corners. Allow the plate to remain in the bath from two to five minutes, according to temperature ; about two will generally be sufficient in hot weather, and from that to five in colder. Just before finally taking the plate out, move it briskly up and down, by means of the dipper, two or three times, until the liquid flows uniformly, and not in streaks, over the surface. Take it out with the thumb and finger, and by the same corner it was held whilst being coated with collodion; drain, but not too closely, and put it into the dark frame, with a slip of blotting-paper on each of the lower corner wires of the frame ; shut up the slide, throw over it the black cloth, and place it in the camera. There is no difficulty in making the bath if the nitrate of silver be pure and in crystals, and also the water distilled ; but when it may be desirable to avoid the risk of preparing it, and in order to make success more certain, I always keep a stock of the nitrate bath ready prepared.

Never weigh chemicals on the bare scale-pan without paper, and on no account use the lingers, or anything metallic, either to remove from or add to it ; this should always be done with a little clean paper. Do not handle your plate unnecessarily when taking it out of the bath. Let it be put in, holding it by that corner which was necessarily left free from collodion, and by the same corner only, take it out, and continue the further manipulation. It is better to hold it thus than to let the centre of the plate rest on the tips of the fingers during development, as the warmth of the 24 T. GREENISH, THE TRUE PAPIER SAXE, IMPORTED BY T. GREENISH. Experience seems to have satisfactorily decided, that for richness of tone, freedom from metallic spots, and strength to bear prolonged washing, there is no paper at all to be compared with the Papier Saxe. But much of this professedly imported into England, is nothing more than a French paper, and liable to all the objections that have applied to paper from this source; it results in great disappointment, loss of time, and waste of the materials employed. This paper is all that can be desired, and being albumenized with the pure white of fresh eggs only, to which is added a proper proportion of the chlorides, it can be recommended with the utmost confidence, as being clean, spotless, and definite in its resulting tone. Protected from damp it will keep good in any climate. s. d. The full size sheet, 1 7i by 22£, albumenised... 10 0 per quire. The plain Paper 3 6 „ fingers has a tendency to cause unequal development. In all cases where nitrate of silver is employed, distilled water should be used, — not water so-called distilled, which is condensed in laboratories where steam is used, but water distilled and con- densed on a surface which will not contaminate it. Test Papers are of little value in Photography. A delicately acid condition of bath, which is in admirable working condition, will scarcely affect test-paper ; and when test-paper shows the presence of acid, the bath is generally too much so to give deli- cate half-tones. Iodized Collodion of a pale straw colour should be used in conjunction with a bath containing a barely appreciable quantity of acid. When the bath so decreases in quantity that it is necessary to add to it, this should be done with a solution of 40 grains to the ounce ; this increased strength compensates for the greater loss of silver than of liquid. Sometimes the bath becomes surcharged with Iodide of silver, which is apt to cause spots on the plate, the addition of a 40 grain solution has a tendency to remedy this also.

The Slide — should be covered with the focussing cloth when the shutter is being pulled up, to prevent the admission of a ray of light to your plate in the camera, and before the cap of the lens is taken off, carry your focussing cloth over so as to cover the whole of your camera. When in the field, I think it is also necessary to keep the whole of the camera covered with black cloth, having an opening in front just large enough to enable the lens to pass through, and the dark slide should always be covered from the developing room to the camera and back again. It is a good plan also to tie a piece of brown paper over the lens, projecting sufficiently far to prevent diffused light entering the lens and injuring the brilliancy of the picture ; 3 or 4 inches will suffice, and the paper may be tied over at the time of working. The Lens — should always be rubbed with a piece of wash- leather previous to its being screwed into the camera. Atmos- pheric moisture condensing on it dims the surface. 26 T.

Pyrogallic Acid . . 1 grain Glacial Acetic Acid . . 20 drops. Spirits of Wine . . 20 drops. Water .... 1 ounce Mix in these proportions, and put into the bottle labelled “ The Developing Mixture.” Pour a sufficient quantity of this solution . 20, NEW STREET, DORSET SQUARE, N.W. 27 into a clean glass measure ; and having removed the collodion-slide from the camera into the dark room, close the door and look round to see that all white light is excluded. Then, taking the plate by the same corner out of the slide, either place it on a developing stand or hold it by the thumb and finger of the left hand as before. With the right take the measure, and with one sweep of the hand pour over it the developing mixture, taking care that it is not allowed to stand on one spot, but that it covers the whole of the plate as quickly as possible. Keep it moving, but at the same time do not allow any to run off. Continue moving it in one wave, covering the whole plate from side to side while the picture is being developed. Now the assistance of a proper arrangement of the yellow light will be felt. There should be sufficient to enable the operator to see the plate well, in order to form his judgment as to the extent to which the development has proceeded. After proper exposure, a successful result depends mainly upon obtaining sufficient development, yet with- out continuing it too long. In order to determine this, after the development has proceeded until the details are fully out, pour the solution back into the glass, so that the plate may be held up to the yellow light for examination ; and, if necessary, pour the developing solution on the plate again as at first, until the requisite amount of development and intensity is obtained. The quantity of the developing solution necessary should be put into a clean measure ready for the plate when taken from the slide ; care should be taken that the measure be well washed after every development, and also that it is put to stand in a clean place, and on a little blotting paper. The developing solution employed cannot be used a second time ; it is now entirely decomposed. If by long keeping it has become brown, it is better to make fresh, especially when there is anything important on hand. In Landscape Photography, when your picture is developed, put a little of the bath solution, kept for this purpose in a sepa- rate small bottle, into the remaining portion of the developing solution which has just been used, (two or three drops to every drachm), and after well stirring them together, pour the mixture quickly over the sky, allowing it to flow thence over the whole of 28 T. GREENISH. the picture, and back again into the measure, and again pour over the sky, as before. It gives vigour to the picture, and in- tensity to the sky. In portraiture, it must be used very cautiously and sparingly, or it will destroy half-tones. The developing measure must be well washed before fresh developing solution is poured into it. The solution for this purpose should not be used from the bath; the dipper is liable to contamination from the developing solution on the fingers ; a small bottle of it should be kept for this pur- pose only. FIXING. Fill the bottle with crystals of hyposulphite, and add sufficient water to cover them. When the image is sufficiently intense, wash freely with common water, until the water flows without greasiness over the plate. Then pour on it the saturated solution of hypo- sulphite, which will dissolve the yellow salt or iodide of silver that is on the plate ; and this should be done very thoroughly : again wash with water to remove the hyposulphite. The plate can now be examined by daylight, and if satisfactory, continue the washing carefully, using common water, until the last trace of hyposulphite is removed. It is important to remember, that the plate should be well and carefully washed, or the hyposulphite left on it will, when dry, crystallize, and break up the whole of the picture in the course of a short time. Stand the negative on a piece of blotting-paper with its face to the wall, not on the floor of a room, as the vibra- tion caused by walking, throws up dust on the plate. When per- fectly dry, put into your plate-box, until you have time to varnish it ; when it should be taken out of the box, dried again well be- fore the fire. Allow the plate to get cold, if amber varnish be used, or if spirit varnish, apply it whilst warm. Always dry your ne- gative before placing it in the plate-box, or you will most pro- bably have a good portion of the film pulled off the edges by the grooves of the box. After each picture ; and before commencing to take another, the hands should invariably be well washed, and wiped with a dry cloth. 20, NEW STREET, DORSET SQUARE, N.W. 29 It is a good plan to varnish first with spirit varnish, and after- wards to give it a coat of amber varnish. The spirit varnish adheres best to the glass, and the amber forms the harder sur- face. It is very easy to spoil a good negative in the varnishing, by allowing dust to settle ; by over-heating the plate ; or by applying too thin a layer of varnish ; or not allowing it to soak into the collodion, when the film will tear off in printing. EXPOSURE. Experience only can determine with sufficient accuracy the amount of exposure. It must necessarily depend on whether a landscape or portrait lens be used, on the stops required, and also on the amount of light on the object. It is better to com- mence with a short exposure, and gradually increase it, until, by development , all the details of your picture are seen to have been taken ; the pictures of beginners are generally over-exposed and under-developed. This much I may say for general guidance. If after having exposed a plate to the best of your judgment, you find that, in development, the details of the shadows do not appear, and also that your black deposits want transparency, the probability is that the picture is under-exposed. Expose another plate, giving a little more time, and repeat the experiment, if ne- cessary, until you get the details of the shadows. I refer to those parts of the plate, which, while development is proceeding on other portions, show patches of yellow, which remain un- changed, leaving no details. Here, the details should be, but the exposure has not been long enough to impress them. On further exposure they will appear in their proper order of development, after the partfc of the picture better lighted, and there should be no patch of yellow on the plate, that has not its details impressed on it. When a picture is over-exposed, on the application of the de- veloping solution it usually starts out at once, and darkness covers the whole face of the plate, high lights and shadows to- gether. There is transparency, but no relief, and no gradation of tone in any part of it ; and on continuing the development, the 30 T. GREENISH, resulting picture finishes flat ; it has all the detail but there is no distance. If a landscape is taken, and the light brilliant, more especially if it is of importance that the extreme parts be taken sharp to the edges of the plate, the smallest stop should be used. If the day is somewhat dull, and the chief part of the object oc- cupies the centre of the plate, the medium stop may be used, and the exposure must be diminished. And, again, when, for in- stance, a part of a building with a northern aspect is to be taken, (say, a doorway,) the full aperbure should be used, and the time must necessarily depend on the amount of light. A portrait lens with a full aperture can very rarely be used out of doors ; except in dull weather ; at other times, a stop varying in size according to the light must be placed between the two combinations. In using either landscape or portrait lens, the image on the focussing glass should be clear and well defined, and without it, a good picture cannot be taken ; the reverse of this is noticed when too much diffused light gains admittance. Experience is the only guide, and the eye will readily detect the imperfect image on the ground glass. One day’s practice in the field, will do more to make the beginner understand this part of photography, than any amount of written instruction can pos- sibly do. In portraiture, a due proportion of light and shade is a matter of the utmost importance ; without it there can be no good resulting portrait. It is on this account, that portraits taken in the open air are rarely pleasing. In landscape or architectural photography, the direction of the light with reference to the object should be studied, and the photograph be taken at a time when the shadows are most effective. It is not often that more than one hour is available by the photographer, for the particular subj ect chosen. Beyond that time, the shadows have so altered that it is no longer the picture, although yet it may be a good photograph. Of course, in no case, can a photograph be taken with the sun shining into the lens of the camera. 20, NEW STREET, DORSET SQUARE, N.W. 31 PRINTING. there is no part of photography more instructive to the amateur than that of printing, for whatever doubt may have previously existed in his mind, as to the quality of the negative, will be satisfactorily settled as soon as a fair impression of it has been produced on paper. There the inartistic character of the picture, want of half tones, and absence of those details which give so much value to the finished picture, will be clearly perceptible. And if the lessons here conveyed are pro- perly borne in mind, the time spent in mastering this somewhat difficult part of photography, will not have been spent in vain. There certainly is not the same stimulus to print, that there is to take the photograph. But when after some little experience, it is perceived, that in many instances the full beauty of a pho- tograph can never be brought out, unless it be properly printed, the printing of photographs will not be lightly passed over. I may venture to say, that if you don’t print at least some of your negatives, your progress in photography will be very unsa- tisfactory, as a good professional printer will produce passable prints from a negative, inferior to that which ought to be aimed at. Albumenized Paper. — This should have a good even surface, and be free from blemishes or metallic spots. The Papier Saxe or Saxony paper, gives the best tones and permits of more prolonged washing, than either English or French papers ; it is also more free from particles of metal, but it should be kept in a dry place. Sensitizing Solution. — Make a solution of 60 grains of nitrate of silver to each ounce of water, sufficient to cover fully the bottom of your glass or porcelain dish, carefully float the albu- menized surface on this solution from 1 to 5 minutes. Take up one corner with a glass rod or horn pliers, and after it has ceased to drip, pin it up ; when quite dry, it is ready for the pressure frame. Take the negative which has already been varnished, wipe both it and the glass in the pressure frame quite clean and place it with varnished side up in the pressure frame ; and on the negatived and varnished surface, place the sensitized sur- 32 T. GREENISH, face of the paper ; fasten it down by the usual means, and expose to sun or diffused light ; examine it occasionally by raising one half of the back of the pressure frame, and, when sufficiently printed, place it in a portfolio excluded from the light, to be ready for the toning process. The method of toning now generally adopted, has the merit of great simplicity, and the probability of greater permanency, than any other which has preceded it, it is as follows : — Wash the prints in water, and subsequently in water to which a little common salt has been added, then dissolve 4 to 6 grains of chloride of gold in one pint of water, and into this put a slip of litmus paper, the acid properties of the solution of gold will speedily change the blue colour of the litmus to red. Make another solution with a few grains of carbonate of soda, and whilst stirring with a glass rod, add the solution of carbonate of soda, until the reddened litmus is restored to its original blue. Or, to save trouble, 30 grains of carbonate of soda will be suffi- cient for this quantity. Into this mixture, put the prints which by well washing have been entirely cleansed from the free nitrate of silver, acquired in the sensitizing bath, and keep them moving, carefully watching them. A change is soon perceived. They ac- quire a deep violet deepening in tint, according to the extent to which the printing has been carried. Take them out, wash them, then put them into a solution of hyposulphite of soda ; 1 part to 6 parts of water, where they should remain 5 minutes, then remove them and wash well with at least half a dozen waters, afterwards allow them to remain for from 12 to 24 hours, occasionally changing the water, when they may be pinned up to dry. In this process of toning, it is necessary that the printing and also the toning be a little deeper than was necessary in the old process ; and also that the sensitizing solution be kept up to its full strength. Great care and some little judgment is required to produce the beautiful results, of which this process is certainly capable. It is well not to make more of the toning solution at one time, than is necessary for the day, or at most two continuous days, 20, NEW STREET, DORSET SQUARE, N.W. 33 as it undergoes a change, and its toning property is materially impaired by keeping. One of the best of the older processes is the following ; and one that for its warm and brilliant tones, when proper care has been used, is not excelled. Place the prints which have been removed from the pressure frame, in a solution of 1 part of hyposulphite to 6 parts of water for five minutes, then pass them through water, and imme- diately after into the following solution, which has been made at least 24 hours previously. Hyposulphite of soda . . . lib. 16 Ounces. Water 21b. 32 Fluid Ounces. Chloride of Gold dissolved in water 10 Grains ; Mix. Continue to use this bath so long as it gives the required bril- liant tones, then put it aside and make another ; if used too long, the white of the prints acquire a disagreeable yellowness. The prints, when removed from this, have only to be well washed in the same manner as above directed. For the latter pro- cess when the toning bath as given above, is in good working condition, the photographs should be printed only a little deeper than it is desired they should be when finished, but with the first process they must be much deeper. Great care should be taken in handling the albumenized paper before, but especially after it has been sensitized. When printing, the hands should be very clean, and the paper touched on its sensitized surface as seldom as possible. Any want of care or cleanliness here, will be apparent when the print is toned, and result in its being totally spoiled. The plain albumenized paper, if protected from damp, may be kept for any length of time, but when once sensi- tized, it should be used as soon as practicable, or, if kept, it should, when dry, be rolled up in brown paper, and put away in the dark. In winter it will keep for several days, but in summer time it will lose its colour, in less than twenty-four hours. The sensitizing solution, after albumenized paper has been floated on it, becomes of a brown colour. Before being used c 34 T. GREENISH, again, a little Kaolin should be put into the filter, through which it is proposed to pass it, when the solution will be deprived of its colour, and filter through bright ; if not, it must be returned again to the filter, until it does so. The finished prints may be mounted with a solution of starch ; and afterwards, to give the surface a finish, they may be rolled by any one of the wholesale card-makers, or brightened with a hand-burnisher. CLOSING REMARKS. To those who are about to leave England with Photographic Apparatus and necessary chemicals, anticipating pleasure from the practice of the Art in foreign lands so rich in objects of varied interest, and so well adapted for the faithful delineation of Pho- tography : deserted temples, the former magnificence of which cannot now be adequately described ; lovely scenery on which, in after years, the memory delights to dwell ; works of art and science that embody the highest conceptions of men’s intellect ; delicate tracery, which, in deference to a beautiful climate, the hand of time has spared, together with a thousand other objects of interest and utility, which Photography alone can adequately portray. But it must be Photography in substance, and not in name only. It is to those that clear, concise and intelligible instruction must be of incalculable value. Photographic results are dependent on definite laws; and careful, pains-taking, appli- cation must result in complete success. Nothing can be more certain ; and when once acquired, few attainments possess such thrilling interest. Let the apparatus be plain, well and substan- 20, NEW STREET, DORSET SQUARE, N.W. 35 tially made, the camera sliding and brass-bound, the tripod firm, the box iron-bound with divisions for the chemicals, and these latter well secured with glass stoppers ; gutta percha baths of the best make, and other appliances of the same material, to avoid the risk of breakage. As few hinges as possible, and not more screws to take care of than are absolutely necessary ; in actual work they are an incumbrance, and their loss is irreparable. Avoid the varied attempts at portability which embody so many fallacies, and have been the true source of so many failures in Photography. If you purpose success, you cannot reduce your apparatus and other necessaries beyond a certain limit, without materially impairing their efficiency. Avoid these contrivances from prudential motives, as a mistaken economy can only result in disappointment ; an experience of some years has convinced me of this ; and the remarks of those whom I have supplied, and whose results have been forwarded me, confirm the opinion I have long acted on in advising those whose requirements I have undertaken to supply. I would add, that before you leave Eng- land, you should give one day at least to Photography in the field, using an efficient tent, such as the one I have described, and the apparatus you intend to take with you. You will then at once be placed in the same circumstances as when abroad, and the subjects will partake of the same character. If you fail now to take your picture properly, how is it possible that you can suc- ceed, where there is no friendly hand to assist you, and where the loss of material wasted, is not so easily supplied, and the places of interest probably never again revisited. 36 T. GREENISH, f ESTIMATES OF Complete Sets of it apparatus, With the Chemicals and other Appliances. For the guidance of Purchasers of Apparatus, a few examples are given of complete sets of convenient and moderate sized Apparatus, &c., to be considered rather as suggestive than definite. It should be borne in mind, that when the price of a Set of Apparatus is quoted with the usual accompanying phrase, “and Chemicals” that the quantity of the latter supplied with the Apparatus, must of necessity materially influence the value of the whole. In the following estimates a good supply of Chemicals with every other requisite for the practice of the art is included. FOR STEREOSCOPIC VIEWS AND PORTRAITS.

A Tent may be advantageously added to this set, also an extra supply of Chemicals. If for India or the Colonies, the Camera and the woodwork should be brass bound. The most complete instruction is afforded with every set of Apparatus. The sets here indicated are merely suggestive. Any other arrangement of Apparatus either for Portraits or Views, or for both combined, can be most readily determined on, to suit the wishes and requirements of the Purchaser. It is necessary only to state the size of the Picture required, and whether the Lens shall be adapted for Portraits also ; and in addition to this, whether for foreign use, when an extra supply of Chemicals packed in a separate box for stock, is very desirable. An estimated arrangement can be forwarded, immediately on the receipt of a wish to that effect. 20, NEW STREET, DORSET SQUARE, N.W. 39 INSTRUCTION AND EVERY OTHER REQUISITE IN THE PRACTICE OF Cameras and Camera Stands, of the best Makers, at their Published Prices.

They are not published, although it is probable they will be so. Mr. Greknish is not an artist by profession, although his works display much artistic skill, and have that degree of perfection which can only arise from the capabilities of art. He is, however, a Chemist; and these Views have been obtained chiefly as experiments, in which he has been eminently successful. There has been no theme as yet taken up so likely to be universally attractive as that which this gentleman has made his study,— no Architecture of the Kingdom presents Views of so much interest as those supplied by the English Cathedrals.” THOMAS GREENISH, pijotograpfjtc (Efjemtst, 20, NEW STREET, DORSET SQUARE, N.W.
