Finally having enough freezer space to accomodate holding my mixed Kodak E6 Single Use chemistry, I'm going to freeze the mixed chemistry to avoid the hassle of mixing partial amounts every time I develop film. Can the color developer parts 3A and 3B be mixed and frozen or should they be frozen separately and mixed just before use. I hope they can because I just mixed them without thinking but I would like to know this for future reference. Thanks.
