Lesson plan
Half-frame camera
half-frame SLR Half-frame cameras, also called single-frame or split-frame cameras, are film cameras compatible with 35mm film types. These cameras capture congruent shots that take up half of each individual frame in the roll of film. They can be still frame or motion picture cameras and are the standard format of 35mm movie cameras. This is commonly expressed, more technically, as 18×24 mm using 18×24 mm of a regular 135 film. It is closer to the normal frame size of a 35 mm motion film. This leaves half frame cameras to derive their film plate size from the aspect ratio, and frame size that was first designated by Thomas Edison (24.89 by 18.67 millimetres or 0.980 by 0.735 inches) at the dawn of the motion picture industry. Traditionally, the additional film width on motion picture film is used for audio in later film standards, although the original patent for sound on film is derived from the 1880s.
