- 35mm reels usually contain newspapers, books, engineering drawings, maps, blueprints, and other large format documents, but the truth is anything that has ever been on paper can be on 35mm, including 8.5 x 11 A-Sized documents.
If you have any experience in the micrographics industry or a knowledge of ANSI standards, you would think that document imaging guidelines are enforced, but they are not. If, for some reason or another, a microfilming company wanted to reduce documents to 12x or 16x reduction ratio, it would be on 35mm.
- The number of frames on 35mm roll film varies, but generally speaking a 35mm microfilm scanning results in around 500 images per reel. Since there were no standards, however, theoretically a reel could contain anywhere from 1 image to 1200+ images. Most of them are 100 feet.
- The price of a 35mm microfilm scanning is slightly higher than a 16mm microfilm conversion due to the size of the images and number of frames on a reel.
- A 35mm microfilm conversion can result in a bi-tonal or greyscale image (Group IV uncompressed, LZW, or other compressions). The images can be named or indexed anything. Typical file formats are PDF, TIFF, or JPEG.
- A microfilm conversion is not the same as a microfiche conversion, as those terms are commonly confused. Part of the confusion is that there are 35mm jacketed microfiche, which were at one time on roll film.
- The reels are usually converted at 200DPI, 300DPI, or 400DPI. (DPI = dots per inch/scanning resolution)
