CATALOGUE OE THE APPARATUS AND MATERIALS REQUIRED IN THE PRACTICE OF PHOTOGRAPHY, &c. &c. The Publishers have great satisfaction in presenting to the followers of the Photographic Art a new and revised Edition of their Catalogue of the Apparatus and Materials required in the practice of it, and adapted for the Professor, Amateur, or Artist. The increasing interest taken in the progress of this fascinating art has enabled them to add many new instruments to their former collec tion. They still continue the sole Agents for the sale of the Celebrated Daguerreotype Lenses, manufactured by Voigtlander & Son of Vienna, which remain un- surpassed by any others. For the purpose of testing the qualities of these and other Lenses, Messrs. Knight have erected a suitable room with every convenience for trying them, and also for giving practical instruction in the various branches of the Photographic Art. » $ DAGUERREOTYPE CAMERAS. 5 Fig. 1.

The whole packed in portable case, with lock and key 23 0 0 The above Cameras, with the exception of the last, being fitted only with single Achromatic Lenses, are chiefly intended for taking views, copying pictures, or other inanimate objects. For the purpose of por- trait taking from life, where quickness is a great desideratum, a double combination of Lenses is necessary. When, therefore, the Camera is required for both purposes, any of the following may be added, increas- ing the expense by the cost of the Lens selected, and a slight addition for adapting the Camera to both set of glasses. $ * # *• IMPROVED DOUBLE ACHROMATIC LENSES. 11 IMPROVED DOUBLE ACHROMATIC LENSES. Manufactured by Voigteander and Son, Vienna, from Calculations made by Professor Petzval. Sole Agents for the United Kingdom, George Knight & Sons, Foster Lane, Cheapside, London. No. 1. Consists of a combination of Achromatic Lenses of the re- spective diameters of 1 J in. and If in., with full aperture, the com- bined focus being 3§ in., handsomely mounted in brass, with rack and pinion adjustment, suited for plates up to the size of 4 in. by 3 in. This lens is well adapted for portraits of a small size, groups, and views, 6 No. 2. Consists of a combination of Achromatic Lenses, of the respective diameters of 2 in. and 2 l g in., with full aperture, the com- bined focus being 7 in., handsomely mounted in brass, with rack and pinion adjustment, suited for plates up to the size of 5g in. by 4 in. This lens is well adapted for portraits, whole length figures, and groups. It is provided with a diaphragm or stop to be fixed in front of the first glass when views of landscapes, &c. are taken, 10 No. 3. Consists of a combination of Achromatic Lenses of the re- spective diameters of 3| in. and 3-jL in., with full aperture, the com- bined focus being 7 5 in., handsomely mounted in brass, with rack and pinion adjustment, suited for plates up to the size of in. by 4f in. This lense is well adapted for taking portraits, figures, and groups ; it possesses advantages over the smaller size lenses, admitting a greater quantity of light, and consequently acting quicker. The in- creased distance from the Camera of the object taken causes the pro- portions to be better preserved. This lens is also provided with a diaphragm, to be fixed in front of the first glass when views of land- scapes are taken, 6 0 0 0 0 0 W 12 V OIGTLANDER AND SON'S DAGUERREOTYPE LENSES. LENSES No. 4 and 5. These lenses, which have only very lately been introduced by Messrs. Voigtlander and Son, possess very considerable advantages, and will be found invaluable to the professional daguerreotypist, artist, &c. No. 4. Consists of a combination of Achromatic Lenses of the re- spective diameters of 2j| in. and 3| in., with full aperture, the combined focus being only 2£ in. ; handsomely mounted in brass, with rack and pinion adjustment ; suited for plates to the size of 3 J in. by 2f in. The short focus, combined with the large aperture of this lense, enables it to command an intensity of light four times greater than any other, at the same time its defining power is unequalled. It is admir- ably suited for taking portraits in private rooms and other places not generally adapted for the purpose, as also portraits of children. Good pictures can be produced with it in bad weather and on dull days, when other lenses would be useless. It is provided with a diaphragm for views, copying pictures, &c No. 5. This matchless lens consists of a combination of Achromatics, of the respective diameters of 3 in. and 3| in. full aperture, the com- bined focus being 5| in., handsomely mounted in brass, with rack and pinion adjustment. This lens, which is of similar construction to the No. 4 is, when used with its full aperture, 'capable of perfectly covering the half plate of the size of 6^ in. by 4-f in. It commands an immense power of light, working in a third less time than the No. 1, 2, and 3 lenses. With the 2 in. diaphragm the light is less, but it works sharper to the edges of the picture. By a recent addition to this instrument, the first lens of the combination can be used alone for inanimate objects, views, Calotype pictures, &c. For this purpose it must be unscrewed from the body and screwed into the separate brass plate, the deep diaphragm simply slid over it ; it is then fixed to a larger Camera, the focus of the single lens being longer, it produces magnificent pictures 8 in. by 6 in No. 6. Consists of a combination of Achromatic Lenses of the respective diameters of 4| in. and 4 T 5 S in., mounted in brass, but without rack adjustment, the combined focus being 10 in. The above power- ful combination is capable of taking a clearly defined picture, either on plate or paper, of the size of 12 in. square, In all these lenses the focus is measured from the back lens to the ground glass, an image being received on the latter from a distant object. In the former edition it was measured from the centre of the combination. 45 d. 23 0 0 35 0 ENGLISH ACHROMATIC LENSES. 13 SUPERIOR COMPOUND ARRANGEMENT OF ENGLISH ACHROMATIC LENSES FOR TAKING PORTRAITS.

It having been clearly ascertained that many very excellent Lenses differ as to their chemical and optical focus, a ready method of ascer- taining the exact difference is very useful to the practical photographer. Claudet’s apparatus made portable, so that when not in use the whole packs into a box, which forms the stand. (Fig. 10.) 2 10 0 It consists of a series of fans arranged round a cylinder, but at dif- ferent distances ; when placed opposite the Camera, and viewed on the ground glass, it forms a circle. The Lens being adjusted to one of the fans, say the centre one, the impression is taken on a prepared plate, when probably it will be found that the fan most clearly defined on the ground glass is very indistinctly represented on the plate, but that another screen, 3 or 4 inches behind it, is far more clearly represented. This will enable the operator at once to see how to manage in order to obtain a perfect picture in good focus. 16 FOCUSSING APPARATUS. £ s. d KNIGHT’S FOCUSSING APPARATUS. It consists of a brass frame, to be attached to the back of any Camera in the place of the ground glass. (Fig. 11.) 1 5 0 There are two grooves, one vertical, in which is placed the ground glass, and the other at an angle, cutting the vertical one in the centre. Having obtained a good focus on the ground glass, it is removed, and the prepared plate introduced in the inclined groove, and an image impressed, say of a large newspaper. If the chemical and optical focus agree, the print will be most distinct in the centre, where it cuts the vertical groove in which the ground glass was placed - } but if the two foci do not agree, some other part of the plate will have the most distinct image. If the chemical focus be longer than the visual, the most distinct image will be on that part of the plate inclining away from the Lens, and at some part of the plate corresponding with the amount of error. This amount can be read off in decimal parts of an inch, by means of a scale at the side of the brass frame ; and after having accurately obtained this distance, it is easy afterwards to move the tube containing the Lens in or out a distance corresponding to the division of the scale indicating the deviation of the true from the photogenic focus.

In the centre is a circular hole from one inch to two and a half inches diameter, according to the size of the holder ; into this a cylindrical brass plug is made to fit very accurately, and by means of a screw in the side of the wood block, which can be turned by an ordinary screw- driver : it can be firmly fixed or released at pleasure. To the under surface of this plug is attached a composition which, on being heated, becomes temporarily adhesive, and enables the operator to fix the Daguerreotype plate firmly to the holder, and retains it there during the operation of cleaning and polishing ; and when finished it can be readily removed without any danger of bending the plate, or, as it is commonly called, 11 Buckling.” The advantages this holder possesses over most others are the fol- lowing : — The plate is secured very firmly ; the whole surface is equally pressed upon ; there is no occasion to bend either the corners or edges of the plate ; and it can be either clamped to the table and the plate cleaned and buffed upon it, or the operation may be reversed, and the buff or buffs being a fixture, the plate fixed to this plate- holder is cleaned upon them. For the thin French plates it is in- valuable. 24 CLEANING AND POLISHING APPARATUS. £ s. d. To use this plate-holder proceed as follows : — The plate to be cleaned is placed with its silver side downwards on any even and clean surface — a buff, for instance ; turn the screw C and remove the brass centre B, place the wood block A evenly on the plate ; warm the composition on the underside of the brass plug B before the fire or lamp, and, returning it to its place, press it down on the plate ; now remove the hand to the wood block, secure the brass plug firmly by the side screw C. The plate will be now firmly se- cured to the holder, and may be cleaned and polished as the operator may see fit. To remove the plate, turn the screw and take away the wood block A. A very gentle force will release the plate from the metal plug. Apparatus for bending the edges of thin Daguerreotype plates, a plan adopted by many artists previous to buffing.

OPINIONS OF THE PRESS. “ In this little work we have simple directions given for pursuing every Photogenic process of any value ; and the character of those points of information which are most necessary is greatly improved from the amount of industrious research which the author has himself bestowed on the subject. The Photogenic Manipulation is one of the most useful Manuals with which we are acquainted.” — Athenceum. “ Mr. Bingham, who is well known for his introduction of some useful compounds of iodine and bromine for rendering sensitive the silver plates for Daguerreotype, has executed his task with much ability ; and we can recommend the Photogenic Mani- pulation to all persons interested in the practice of “ sun painting” as an exceedingly useful Manual .” — Art Union Magazine.
