Are there any special measures and materials available to seal a room completely off the light, or simple solid doors are enough.
The only room i could use for film processing basically has no direct source of stray light (windows, keyholes, doors with gap to frame) BUT....
After checking the room for 5 minutes staring in complete blackness, your eyes start to adapt and you see that the step-like door frame still is able to leak light.
If i pack the perimeter of doors with paper, i can start to see a fain fuzzy glow around the doors after 30 minutes.
How do you determine if the "darkness" level is enough for film processing.
Btw. some people have told me that you cannot work with B&W film under red light, because most current films are sensitive to it.
Is this true for B&W as well?
How do you make prints then, or is the paper still insensitive ?
