Focal-plane shutters may also produce image distortion of very fast-moving objects or when panned rapidly, as described in the Rolling shutter article. A large relative difference between a slow wipe speed and a narrow curtain slit results in distortion because one side of the frame is exposed at a noticeably later instant than the other and the object's interim movement is imaged.
Consequently, photographers demanding higher quality in sectors such as weddings, portraiture and fashion where medium format film predominated were the last to switch once resolution began to reach acceptable levels with the advent of 'full frame' sensors, 'digital backs' and medium format digital cameras. Film camera sales based on CIPA ...

The angle of view of a lens depends upon its focal length and the camera's image sensor size; a sensor smaller than 35 mm film format (36×24 mm frame) gives a narrower angle of view for a lens of a given focal length than a camera equipped with a full-frame (35 mm) sensor.
Shutter lag is the time between the shutter release being pressed and the exposure starting. While this delay was insignificant on most film and some digital cameras, many digital cameras have significant delay, which can be a problem with fast-moving subjects as in sports and other action photography.
The right-hand diagram shows the view from the camera's perspective: the two figures appear to be standing in an archway in an enormous stone block. The Schüfftan process is a special effect in filmmaking named after its inventor, German cinematographer Eugen Schüfftan (1893–1977).
The practical amount of enlargement (irrespective of the enlarger structure) will depend upon the grain size of the negative, the sharpness (accuracy) of both the camera and projector lenses, blur in the image due to subject motion, focus, and camera shake during the exposure. The intended viewing distance for the final product is a consideration.
Film is typically loaded one sheet at a time into a special holder. Each film holder can hold two sheets of film - one on each side of the holder. Different holders can be loaded with different film; the type of film can be changed from one photograph to the next. Typical film sizes are 4 inch by 5 inch (4"×5") and 8 inch by 10 inch (8"×10").
