I want to try cross-processing, what film should I use?
If you want to try out cross-processing a.k.a. x-pro, use slide film which is also known as positive film or reversal film.
This film uses E-6 chemicals, but in cross-processing it is developed in the ‘wrong’ chemicals. The slide film is developed using C-41, which is used in colour negative film.
