how to cut film in the dark?

[unityofsaints]

Dahle rotary cutter + film changing tent for me. I originally bought the tent to load 8x10 holders but I'm discovering more and more uses for it: cutting film, cutting paper, loading development drums, etc. etc.

An old rotatrim rotary cutter. I simply measured from the cutting edge and put down a strip of masking tape as a guide. In the dark it is easy to position the film (or printing paper) by putting the edge against the tape by feel. Then slide the cutter. I normally use it to trim prints for dry mounting, or to cut 11x14 paper into two 5.5x14 strips for test prints, but it works for sheet film as well.

I used my guillotine cutter once to cut processed film, only to find little brass shavings all over it. So, that's a thing, and you probably don't want to do what I did, whatever that was.

Hello. All you need is a film changer tent (or a large cardboard box), a cheap Chinese Wi-Fi infrared camera (950nm is the best choice, but 850nm will work too) and a smartphone. Place the camera inside the tent (cover all light sources on it, such as power LEDs, etc. with black tape), connect it to the smartphone via Wifi and set the smartphone in front of you on any tripod. That's all. After that, you can use any cutter at all, or even ordinary scissors)))
