THE Eastman Portrait Dif-fusion Disks have not only become very popular among photographers who are interested in producing soft focus effects, but are being used in many cases to make proof retouching unnecessary. The A Disk is the one used for this purpose as the diffusion is just enough to reduce the harshness of sharp lines, freckles and blemishes of the skin.

The A Disk gives a very pleasing softness that could not, by any stretch of imagination, be called fuzzy or freakish. But because it does give the lines of the face a natural softness, it does away with much of the need for retouching and so preserves the likeness that is so often destroyed by too free a use of the pencil.

The B Diffusion Disks are used when a greater amount of diffusion is desired, but even with these Disks the results are what one would call conservative. And they are always the same because the Disks are specially constructed to produce a certain positive effect which is invariable.

A great many indifferent results are secured with soft focus lenses due entirely to a lack of knowledge of the particular lens that is being used and the way to make the most of its good qualities.

Diffusion Disks, on the other hand, will not produce the objectionable effects of improper diffusion unless no thought whatever is given to focusing. When an image is focused sharp with your regular lens and the Diffusion Disk is slipped in front, the result is all that could be asked for.

The diffusion depends somewhat upon the lens you use, as an identical result could not be expected with different lenses. But when you have secured a sharp image with your lens the Diffusion Disk will always give you the same amount of diffusion. Another point in favor of the disk is the fact that it does not require any additional exposure.

With the soft focus lens you must stop down to reduce diffusion. With the Diffusion Disks use your ordinary lens, wide open, and choose the Disk giving the diffusion you want.

As to quality of diffusion, there is no question as to results. The Disk does what the soft focus lens does, but in a different way. The center of the soft focus lens gives a sharp image and the outer edges a diffused image. The center of the Disk gives a sharp lens image and the outer edges of the Disk diffuses the lens image, so there are really two images, one sharp and one diffused.

The result is an image in which the structure is fully preserved, there is plenty of detail and yet there is very little need of retouching. Retouching is not so much of a fault as it was at one time, but still it is difficult to find a retouched portrait in which a great deal of the likeness is not destroyed.

Because these Disks can be used with any lens which will give a good sharp image, they have become very popular with the portrait photographer and have helped to make good soft focus photographs more popular with the public.
