The two brothers who founded the company started as a small business shooting music and wedding photography, building and modifying cameras and lenses, then moved on to chemically adapting motion picture film so it could be processed at photo labs.

This collaborative approach to manufacturing increases efficiency and supports the necessary infrastructure for film to exist, while still allowing the company to operate with a very small footprint.

For their color negative films, CineStill works with Eastman Kodak to produce modified versions of Kodak's motion picture cinema emulsions, allowing them to be developed with the C-41 process rather than the Eastman Color Negative (ECN) process.

Due to having no anti-halation backing, CineStill film exhibits a glowing effect on the image in areas with strong overexposure.

Despite there being no Remjet layer, all ECN-2 steps must be followed to achieve proper development for motion picture negatives.

Similar to the 800T, 50D has its remjet layer removed which results in a slight halation effect.
