Compare the characteristics of platform and rotary miniature cameras.

Answer: The characteristics of the rotary camera are:

First, only 16MM film can be used for shooting, which is small in size and convenient to install and carry.

Second, the shooting speed and efficiency are high.

Third, it is only suitable for shooting single-page manuscripts with good paper quality and certain specifications, and cannot shoot manuscripts with thick paper quality, large format, poor paper quality and bound volumes.

4. Microfilm of single-line and double-line images can be made.

Fifth, the shooting quality of images is not as good as that of platform microfilm cameras.

Characteristics of flat-panel microfilm camera:

First, the platform microfilm camera is to put the manuscript on the manuscript table perpendicular to the optical axis of the lens, and expose and image it with photosensitive film at rest. According to different microfilm specifications, microfilm cameras can be divided into 16MM, 35MM or 16/35MM dual-purpose, flat panel and window card.

Second, the original picture of the 35MM platform microfilm camera is large (above A3 paper), which requires higher image quality of microfilm.

3. The 16MM flat microfilm camera is mainly used for shooting small-format (A3 or below) originals and those that need quick retrieval. It is small in size and equipped with a device that can shoot search symbols.
