Time Of Day. The light conditions will have much to do with your success or failure with this class of subject. You should try to make the exposure when the sun or strong light is not on the windows included in the view. Then, again, the sun should not strike those windows which supply the strongest amount of illumination.
Weather Conditions. When the weather is very bright a good time of day for such exposures is at the noon hour when the sun is directly overhead. You will then have more even illumination, yet have snappy highlights with illuminated shadows. It is far better to make church interiors, if you rely on daylight alone for your illumination, when the weather is slightly cloudy, as this will give much softer results. A longer exposure, of course, will be required, and it may be necessary to give double the exposure under such conditions as when the sun is shining brightly.
Plates To Use. The rapid non-halation ortho plate is best for this purpose, yet the ordinary rapid plate will be found very satisfactory, especially when the Special Development is employed. It must be remembered that when the special method of development is employed, from three to four times the normal exposure must be given.
Exposure. The exact amount of exposure required for all such work cannot be given here, as there are few interiors giving the same amount of actinic light, or that are arranged in the same manner. Frequently the exposure will be at least half an hour long. In the majority of cases, however, it will be far in excess of this. Sometimes it will be necessary to leave the lens uncapped for several hours, in order to secure proper detail in all portions of the interior. Careful study of the exposures given the interiors illustrated herein, and a little practice and experience, will enable you to judge quite accurately, by the appearance of the image on the ground-glass, the amount of exposure necessary.
Stores, Store-Fronts And Bank Interiors. The photographs of interiors of stores, show-windows, banks and business places are made usually for advertising purposes. Banks are sometimes photographed for their architecture. Even then, if views are made with the idea of giving one a general impression of the appearance of the interior of the building, the point of view is all important. The view should be made from the main entrance to the building; so if the photographs are used for advertising purposes, customers upon entering will recognize the place by the picture published. The next consideration is the general arrangement of the interior and the light conditions.
Illumination. Most store rooms receive all of their illumination from the large front windows, thereby causing the strongest light to fall on the objects nearest the camera. If the room is very deep (long) you will, usually, find a skylight in the center of the room, which supplies illumination for the central parts, and as the rear of the room usually has a few small windows, there will be sufficient light to illuminate the entire room uniformly. The light for interiors of store-rooms, banks, etc., like all interiors, gives better effects at some hours of the day than others, and usually, when the light enters the room at a slight angle, it gives better results than if falling broadly on the objects. With the light falling at an angle you have some slight shadows which give relief to the high-lights, thus overcoming flat effects.
