Weird one but I think I know...

... What the cause is.

Just pulled a roll of fp4 out the tank that was shot through the RB67. The roll has been in the camera for 14months or so judging by what's on the first 6 frames. Frame 7 looks okay, that would have been the one in the breach so to speak. 8-10 look mottled or something on the negative. Not scanned them but it'll be very obvious given I seen it as soon as I pulled it out.

I reckon this is the backing paper as it get progressively worse. Though I've not had this problem with Ilford before.

Thoughts?

I've experienced this with a couple of films though cannot recall which ...definetly not FP4 but I didn't use it in roll film anyway.

The experience i had however was with the originally exposed negs and sat in camera for a few months being mottled very extensively whilst the last few frames exposed and thus developed quite soon following exposure were fine.

Simply put it down to the emulsion degrading following being exposed .

How to avoid...simple, expose and dev the complete roll as quickly as possible.
Alternatively pack in roll film and shoot exclusively sheet film

Only roll of film I've shot in 14 months but I can't stop my rb would get lonely.

Suspect next time I'll just finish the roll on the kids or cats.

It is amazing at times when we can't get thru' 10 shots on a 120 film camera.......even for 35mm to take 10 shots when we have run out of things to shoot can be a problem but at least we don't have the problem of backing paper.
