Cameras - Camera Parts

The fixed focus or box cameras contain no scale. As they are all a fixed general focus, such cameras need no focusing, and whatever is visible in the finder will appear in focus on the plate or film. But with all other folding cameras containing focusing scale or ground-glass, the focus must be obtained by the above method and not in the finder. Use the finder only for locating the view on the plate. Always remember, first, to locate the view in the finder, for whatever is visible in the finder will be registered on the plate. If the camera is pointed at a building and it looks crowded in the finder, then step back farther from the building until good proportions of margin all around are secured. Judge the distance from the object or building and draw out the bellows until the pointer registers opposite the number of feet which is the distance between the camera and the object. The exposure can now be made.
