180. Instantaneous Exposures

Instantaneous Exposures. (Snap-shots.) Most of the box types of kodaks have shutters which are always set and are operated by pushing the lever alternately to right or left with the thumb. If the spring is pushed the wrong way, the shutter remains unmoved, and no "click" is heard. This, of course, means that the lever should be pushed in the opposite direction. The manipulation of other shutters is clearly defined in paragraphs 53 to 56 of Chapter II (Warm Tones On Gelatin Glossy Paper).

181. To take instantaneous pictures with box kodaks and the cheaper forms of folding kodaks, the object you are photographing should be in strong sunlight, but the camera should never be pointed toward the sun, which should fall from the back or over the shoulder of the operator.

182. "Snap-shots" are made with the largest stop. If a smaller stop or opening is used, the volume of light is so much reduced that it will not sufficiently impress the image on the sensitive emulsion of the film, and failure results. For the use of stops see paragraph 60 of Chapter II (Warm Tones On Gelatin Glossy Paper).

183. Time exposures should not be made unless you place the kodak on something solid, as the slightest jar will cause a blur, or at least, an indistinct image. Therefore, it must rest on some firm support during the exposure. A regular tripod is the best, as you can adjust it to any height. Whether making instantaneous or time exposures, have the instrument perfectly level. In making interior pictures, give time exposures and never point the lens toward a window. If all of the windows cannot be excluded, pull down the shades of such as come into view of the camera.

184. Interior Exposures

Interior Exposures. The exposure necessary for interiors varies according to the light conditions and surroundings. By consulting the table below, you will be able to judge very closely the exposure necessary. This table is for the largest stop. If the kodak is of the box type, with three different openings, use the middle sized stop to obtain more sharpness, and double the time. When the smallest stop is used, give four times the exposure you would give with the largest opening.
