streaks puzzle

My bet is on the dish soap. Why are you using it anyway?

fotoflo will last nearly a lifetime .. and is made for film &c
it only takes a few DROPS in the tank or tray or ...
i am almost done with a small bottle bought in 1981
less than 1/2 oz left which means maybe a few more runs of roll film, and a few runs of sheet film,
and maybe a few sheets of hand coated paper ...

How can dish soap cause light fog? Drying streaks, yes. Light fog, no.

Old n feeble: no i only use ilford, kodak and fuji and i dont bulk load at all.

All I can say is that sure does look like film canister light leaks. AFAIK, it's pretty rare with factory-loaded film... but certainly possibly.

well i'll know for sure in a bit...thanks again guys!

And i'll grab some photoflo next time i see some...might as well i didn't think it lasted so long.

In the 5th and 6th frame, there are shadows of sprocket holes sharp on the film between the sprocket holes. This means the film was, um, touching itself, when it was fogged by light. Could be in the takeup of the camera, could be in the film can... You'll figure it out.

AWESOME CLUE!! absolutely! this is pretty much narrowed down now!

This is FOG not PhotoFlo! It is something with the film cannisters, the processing tank, or the camera.

Ok. When you load you camera, load it in subdued light. Do NOT take it out of its dedicated black plastic canister until its time to actually load it.
When you unload your camera, same thing in reverse; put the film immediately back into the black plastic canister and seal tight.

To test this theory, take a film that you know has never been removed from the black canister, and load your camera either in the darkroom or a changing bag. Unload it in complete darkness as well.
If the film comes out normal you know what went wrong.

This is NOT a PhotoFlo issue. Nowhere near it.

I have had these before when taking chances on old cameras without switching out the seals.

I am pretty sure the leak is from the hinge area of the camera back. The film sits rolled together after every shot on that side of the body, the light leaks in and hits it from the back hinge. It will affect the film at different intervals as it spools together and if your hand is on the side covering it.

Replace seals, you can use a few layers of heavy black tape to test it as well. Tape it across the hinge from top to bottom plates.
