I have a question about edge fogging. I've put an image of the particular kind o f fogging I got on line at:
http://www.uwgb.edu/galta/fog/fogged_edge.htm (underline between "fogged" and "e dge".)
The fogging shows minute striations and occurs on the end of the film which is u nder the flap. It occured with a new holder. It doesn't seem as if it is a matte r of the tape leaking light. In fact, examing the holder itself, it would seem t o me that light leakage of that kind would be difficult because of the light tra ps built into the flap itself. The holder is a Fidelity elite, used only twice b efore this sheet of film. I recall that when I used to fumble around with loadin g 120 film into reels for developing that sometimes I'd get "half-moon" marks th at fogged the film and resulted from mechanical creasing of the film. I did fumb le around a bit loading this particular set of holders (new film Ilford Delta 10 0 seemed a little thinner than the Plus-X I was used to and I had a little troub le finding the holder's grooves the first time around). Can there be mechanical sources of fogging as well as light leaks? Any guesses as the source of this kin d of fogging?
Fortunately, I work digitally after I develop the film, so I was able to clone o ver the damage on the image.
