I just acquired and started using a box 20x24 APHS film (making enlarged negatives). The film is packed in a black plastic envelope, emulsion side up, at least in the box I got. This film is not "notched" to show which side is which, and it is very hard to tell under the red (1-A) safelight. What if I get turned around, etc. -- can you tell which side is which? Granted, I could notch it myself, but is there some way just to tell? -jb
