COVERING POWER

It has held together able members who have done good work for photography in the mother country by their advice and practical help, and the papers of at least one of these workers have attracted world-wide interest and discussion. The appeal of the Mother Society should be responded to generously and promptly, and the energetic hon.

The photographer may of course say that such extreme covering power may not be necessary for him since he does not intend to use his lens as a wide angle, but he realizes how often a lens with enough covering power to a moderately wide-angle lens should b~ used, although the plate used is only that for which the lens itself is listed. The modern camera with its extreme rise from the front practically necessitates the use of what might be called a moderately wide-angle lens such as the Goerz Dagor, if full advantage is to be taken. There are several cameras with such a large rise from the front that it is possible to get the lens almost flush with the top of the plate.

If the latter is a half-plate and a half-plate lens is used, although it may have a medium or even small angle, it will be lifted directly to the top of the plate, not to mention the extreme movement when displayed. is level with the top, the lens must also perform well as a medium-angle lens if it is to be of value on that particular camera. The conclusion is therefore obvious: that coverage power combined with definition is of greatest value for all ordinary work, and coverage power is essential even when the lens is not used as a wide-angle lens.

We all know that beautiful magnifications were made before the introduction of anastigmatism, and are still made by many who have not lost faith in some of the old-fashioned lenses. There is a tendency and a definite tendency, especially when using a wide-angle lens, to fade in brightness towards the edges of the field, which is more pronounced when the lens is strained or even used for it. full helping capacity. With fast straightedges the drop off is not as pronounced, but it is always pronounced on zoom.

It is best to use a lens with a longer focus when magnifying than that used when making the original negative, unless, as we mentioned, distortion is needed to correct. The intensity of the brown deposit is increased by adding a drop or two of the ammonia bath to the tannin solution, but this procedure tends to cause staining in the high light.

But it is the suggestion that there is one exposure which is absolutely correct, which exception must be taken. It is due to the fact that there is usually an ample margin within which all exposures are equally correct that photography in its form can be practiced so successfully at all. In negative-making it is a safe rule never to make changes in the exposure of less than double or half.

If eight is too many, give fo11r or less, if not enough, give sixteen or more. Do not use a dusting brush as it is apt to collect dust and by the force of attraction this dust is likely to be transferred to the board.

Focu ssing

I bought it just as a man in love gets married and my camera honeymoon-oh, what a time. I didn't buy it for the reason already mentioned, and my instructor never mentioned the matter after that. I always looked upon the critic as a drug out of place, and my opinion of him, since I have begun to exhibit my pictures to the public, has not changed; it has been threefold intensified.

My pictures finally found general acceptance; I surrounded myself with memories of my painting work, and my dealer surrounded me with material accounts, but the joy of triumph helped me to ignore those small details. Henceforth, mothers shunned me and fathers threatened evil, but I triumphed; I stuck to my beloved picture-making schemes, my fuzzy-graphic dreams, and my fog.

NOTES on a demonstration by the President of the Royal Photographic Society before the Manchester Amateur Photographic Society. The rubber bichromate process appeals to the image worker from the fact that flexibility with it is a strong point, l\1r said. Mummery during his demonstration to the members of the Manchester Amateur Photographic Society.

The chewing gum solution should be made from common gum arabic and prepared as follows: Four ounces of the gum are placed in a muslin bag and suspended in a wide mouth bottle containing two ounces of cold water; Hot water should not be used. This is ground for a few moments with a glass grinder to obtain a perfect mixture, and when ground the mixture is lifted from the plate into a household dish, using the knife for that purpose, and the rest of the gum added and mixed. Well, then the bichromate solution is.

A piece of glass coated with gelatine, or a spoiled plate, may be soaked in Judson's violet dye for this purpose, and will be best if mounted on the outside of the tank. If accurate focusing is required, the ordinary ground glass will be found to have too much grain to allow the smaller details to be easily seen. This method will be useful when focusing dimly lit interiors or copying dark images.

This may be prepared by dissolving half an ounce of borax in four ounces of water. Half an ounce of shellac is added and the liquid boiled gently until as much of the shellac as possible is dissolved.

The Pictorial Advantages of the Hand Cam era

The above was the title of a lecture delivered by Mr. A. V. Wilkinson in the Toi;ii and Country Journal, before tbe '.\losman Photographic Society at their rooms on the 9th'. In addition to the usual gathering of members, there was an influx of visitors; the subject is one that holds eminent attractions for all interested in photographic processes. lr 'Wilkinson stated that "Natural Color Photography" was based on the principle that all the colors of the spectrum seen in nature are capable of being reproduced by combining the three primary colours. red, yellow and blue. If we make three negatives, of which the print from one reproduces only the yellow, from another only the red, and from the third only the blue, and of these three negative prints or positives are colored correspondingly and correctly superimposed, have a reproduction of the object lifelike.

Wet filters consist of solutions of the proper dyes in a glass cell or tank as shown. Wilkenson received a very hearty vote of thanks at the end of the evening for the tremendous amount of effort he had evidently put into making his lecture as c:Jmplete as possible.
