The SantaColor 100 is a 35mm film rated at ISO 100 with 36 exposures and made for the C41 process. The colors are vibrant and the film offers a wide latitude with a fine grain, resulting in stunning results with punchy reds and lush greens. It has a flexible exposure latitude and can be pushed to 800 ISO with only minor loss of colour accuracy and minor increase in grain. Shot at 400 ISO and pushed +2 stops in development, the film still exhibits accurate colours and an almost grain less look. Film type : Colour negative, air surveillance derived Film speed : 100 ISO Grain: Very fine, but made to create very sharp pictures as it is an air surveillance film Exposure latitude : Wide, with acceptable results from 25 ISO to 800 ISO (with pulling and pushing) Manufacturing : Freshly made in 2022, in the USA and hand spooled in Finland DX coding: No, but most cameras with DX readers default to ISO 100 the film is therefore totally useable in Point and shoot cameras. Processing and scanning: Process: Normal C41, can also be cross processed in E6 for relatively nice positives (exposed at 100 ISO) Compatible with Minilabs and other industrial processing: Yes Base : Mostly clear, slightly orange base. Not directly compatible with the RA4 process. Due to the thinner, clearer base, we recommend you load the film indoors, and definitely not in direct sunlight as this might lead to light leaks on the first frames Scanning : Due to the clearer base, some scanners are confused by the film and give a very red image. This is easily correct when home scanning or when done by a good lab. RA4 Printing: The clear film base requires an additional filter to be compatible with the RA4 process. The easiest way of doing this is to process a strip of unexposed C41 colour negative film and use that as an additional filter to yield normal printing results
