It is akin, says the photographer Douglas Peebles , in its simplicity and obviousness to the advice "if you want to be famous for photographing famous people, begin by photographing ...
Larger stops can cause the light intensity reaching the film or detector to fall off toward the edges of the picture, especially when, for off-axis points, a different stop becomes the aperture stop by virtue of cutting off more light than did the stop that was the aperture stop on the optic axis. The stop location determines the telecentricity ...

Half frame means that the camera uses an 18×24 mm vertical ( portrait ) format, producing twice the pictures on a roll of 135 film as the regular 36×24 mm format.
