Finding the layers in a cross-section of film

A typical film cross-section contains eight layers. The emulsion, which is the film's outermost layer, makes up the first three layers. The emulsion and the film stock themselves are sandwiched between the following four layers of base material. Silver halide crystals are found in the final four layers, and when light shines on them, they produce images.

Conclusion

The cross section of the film actually consists of nine layers in total: three layers of acetate (AA) or vinyl acetate (VA) and six layers of cellulose nitrate (CN).
