Today: Emulsion Type Part 1 -

A film’s emulsion type refers to the composition of its emulsion, whether it was manufactured to be fast, slow, grainy, fine-grained, colorful, pastel, black and white or color, daylight balanced, tungsten balanced, etc. The emulsion type is represented by a number. For Kodak it is a series of four numbers, such as 7248. The “72” always stands for 16mm camera stock, and the same emulsion type is found in 35mm as 5248, “52” being the designation of 35mm.
