How Would I Make A Light-Proof Air Vent, Please?
Hi - thanks for stopping by.
I am in the process of making a dark-room for my photography.
It is stuffy in there and I have an air-vent which lets in light.
I would like to make a cardboard box (or something) that I can put over the air-vent
so that air can flow freely but will still not allow light to venture through.
I would appreciate anyone with any ideas please ;-)
