Watch Man Who "Does the Rest."

Owing to the cold of winter and the difficulty of handling the apparatus

with stiff fingers or heavy gloves, it is well to have as simple an outfit

as possible. An ordinary fixed focus camera is good for this kind of work.

The lens on this style of camera usually works at F-16 and the shutter at

about 1-20 of a second. If the sun is bright, the next smaller stop will

do.

In taking snow pictures, the amateur who presses the button and lets the

dealer do the rest should advise the latter to develop the film with less

contrast than usual. The average dealer usually develops with as much

contrast as possible, and this method would produce a print with blank

white for the snow and hard blocks for the trees.

For more serious workers, a stand camera should be used. The camera should

be provided with a reversible back and a long bellows. An expensive lens

is not necessary. A medium angle lens will be found most useful.

Shutters are apt to work badly when out in the cold, owing to contraction

of the metal parts. This must be allowed for in making the exposure, by

setting it at greater speed.

The focusing cloth should be fastened to the camera. The Eureka focusing

hood is convenient to use. It is made to fit the camera exactly, and has

little elastic loops which slip over the ears and hold the eyepiece in

place while focusing.

A steady tripod and a stay to keep it from slipping are desirable

additions to the outfit. The camera should be protected as much as

possible from dampness and falling snow.

For best results a non-halation plate is necessary. Backed plates will

give better results than plates unbacked. The reason that the light

effects come out so extremely white and hard in many landscapes is because

the strong light from the snow penetrates the sensitive film and is

reflected into it again from the back of the plate, thus making undue

contrasts, and practically giving double exposure. This is known as

halation.

Other Necessary Precautions.

A corrected plate is essential in snow photography, in order that the

effects of light and shadow may not be too glaringly contrasted. The

isochromatic and orthochromatic plates on the market are corrected, and

are the best to use.

The early morning and the late afternoon are the times best suited for

taking snow pictures. The long shadows give interest and character to what

would otherwise be a meaningless expanse of white. The foreground is often

of the greatest interest in snow pictures. The shadows and gradations on

the surface often form the motif for fine compositions.

Never try to crowd too much on one plate. Much may be done with just a few

bushes projecting above the snow. Newly fallen snow should sometimes be

broken up for pictorial effect; and walking once or twice over the

foreground will also aid matters. In doing this, be careful to notice just

how the tracks should run to give the best lines to your picture.

Three Classes of Snow Pictures.

There are practically three classes of snow pictures, of which each

demands its own appropriate development and treatment.

Class 1--Where an expanse of snow is relieved only by delicate shadows, or

where the picture is taken during a snowstorm, when all objects are

rendered more or less indistinct and of a light tone by intervening

particles of snow. For these, the exposure should be short, the rule being

that short exposures increase contrasts, and in scenes of this

description, contrast is what is needed. On a bright day, 1-100 of a

second would be time enough. Very early in the morning or very late in the

afternoon 1-25 of a second will give ample time.

The development for plates in this class may safely be rather

vigorous--that is, with a normal developer and the plate carried to a

fairly good printing destiny. This method gives character to the high

lights, and a pleasing richness to the slight shadows that are present on

the surface of the snow. A pyro developer is good.

Rodinal is a good developer for contrasts when used in these proportions:

Rodinal, one-quarter ounce; water, five ounces; bromide potash; ten per

cent solution, five drops. The temperature of the developer should be kept

from sixty-five to seventy degrees Fahrenheit.

Class 2--When dark masses are in the foreground, with the middle distance

fairly open, and snow broken up--also, when strong contrasts appear in the

view between the snow and other objects--then a longer exposure is

needed--from one-tenth to a full second, according to the light. Use No. 8

stop.

This class of pictures should be developed in a weak solution. A suitable

metal hydroquinone developer is made as follows: Metal, thirty grains;

hydroquinone, thirty grains; twenty ounces of water. Then add sulphide of

soda (crystals) one ounce, and carbonate of soda (crystals) three-quarter

ounce.

Take two ounces of this, and add four ounces of water when there are no

very heavy masses of dark in the foreground, and eight ounces of water

when there are such masses. Before using, add one drop of ten per cent

solution of potassium bromide to each ounce of the solution.

Class 3 embraces snow pictures with figures, street scenes, skating and

sleighing scenes, etc. Short exposure is required here because of the

motion of the figures. The correction must be made in development.

The development of plates of this kind where there are dark objects and

brightly lighted snow or ice in the view is practically the same as in No.
