View Full Version : Guide to Film Notches
I am scanning some B&W 5X7" negatives from the early 1980s and am not able to identify one of the films. Does anyone know of a guide that will allow one to identify sheet films by the notches? I am almost certain it is an Ilford or Kodak B&W film since that is all I used back then. This one has three square notches.

There ought to be a sticky for this on this forum about old notch codes, I've encountered some
in my LF gear acquisitions and it's Googling till you find a site that has old docs that have
the notch codes.
Here's a recent thread I started when I got some 4x5 loaded holders -

Sandy, someone on this forum I think posted this: http://en.wikipedia.org/wiki/Notch_code#Code_notches_and_ISO_speeds_for_Kodak_sheet_films
Seems this was around mid August 2011.
But I don't see any Kodak recent product with three square notches.

I found this; it could be Ansco Isopan or Gevaert Panchromatic.

...it could be Ansco Isopan.
“I have located some negatives from 1955. Three square notches – Ansco Safety Film,” Merg Ross says in this thread (http://www.largeformatphotography.info/forum/showthread.php?t=33198
). “My guess would be Isopan. Hope this helps.”
Thanks for the suggestion that it might be an Ansco film. I found an old film box with the label of GAF Versapan, and the box shows the three square notches for the film code. From what I understand GAF was once Ansco?
The box does not show film speed. I am guessing it was ASA 100? I had totally forgot about buying and using this film. It must have been one of my first film purchases when I started to use the 5X7" format in the mid-1970s.

FWIW, I have a couple boxes of old (70's?) expired GAF pan film and they have two sizeable square notches. Wish I had the boxes with me to give more info.
Kind regards,

I have been scanning my 4x5 films since it hasn't been done yet. I was in high school and used their 4x5 camera for some shots. The shots were taken in around 1988-89. We used Ilford films in the photo class, so my shots were either on FP4 (not plus) or HP5 (not plus).
Edit- It seems we used Kodak for sheet films in school, as this notch code relays to Kodak Plus X Pro.
