Hello everyone,

I've searched the forum for some guidance on these somewhat elementary questions, but I couldn't find any definitive answers, so here goes:

1. How dark does my "darkroom" need to be to safely hand-cut film (by "safely" I mean so as not to cause fogging, ruin the film etc, let alone slice my fingers off)? Can I use a red safelight as I do when printing BW?

2. Same question but for C41 and E6. I assume no safelight for these.

I ask because I'm looking into cutting down 8x10 film to 5x8 (just one cut, phew!) but I don't have a "real" darkroom: I print in a basement dark enough to print BW under safelight without any problems, but definitely not 100% dark (light seeps in from ambient light outdoors, from lights on upstairs and so on).

Thank you for any advice!
