how to fog film

As I have noted before, the acidic hardening B&W fixers should never be used with color. Use non-hardening, neutral pH fixers for color. They should not be re-used for B&W.

thanks. would tf-4 work for something like this? But at 25-35 degrees celsius I would assume. I believe it close to neutral.

TF-4 is alkaline and thus should not be used in color processing. TF-5 is nearly neutral and can be used.
