Most of the roll looks as though the outer edges are overexposed.



Neopan with Rodinal 1:50. 30 secs initial stirring, 10 secs stirring every minute

Maybe not a light leak, I've seen this before. It happened during the development, perhaps wrong agitation, deposit on the reel, tank or something else?

This is to constant for a light leak, perhaps the developer could not reach the sides of the film.

It looks definitely a light leak. Check the light traps around film door. A leak in the developing tank seems far less probable though not impossible.

Cheers, Marty.

It could be a possibility too, though in my experience the clearer area (or darker on the film itself) looked kinda more irregular with definite streaks specially around the sprocket holes.

Found a sample image. One of my very first developments. The camera was fine, no leaks.
Developer (Tetenal Superfin) was nearly 10 years old, but the bottle was unopened until the development.

It's not a light leak as the camera (Chinon CE-3) had new seals in a couple of months ago and has had numerous rolls through it since.

This was my 1st attempt with Rodinal and also stirring rather than inverting.

Other than that, it's not a bad picture of a tree, Martin! Wink Try Barry's
2-Bath, so cheap to make, and temperature friendly. Thinking about
ordering some Diafine for the same reason and gives tight grain, and
you can dev rolls of various ISO together as the dev time is the same
for all.

I got this type of light leaks when I shot my friend's Hasselblad. Light leaks were not from camera, but from a roll that was not wound tight enough around the spool and then subjected to light when removed from camera.

Stirring? Is that a tray-developed sheet, or were you using some non-inversible (daylight loading or ancient) tank? In any case, you should revise your agitation method, the flaw positively looks like as if the exchange between fresh and depleted developer towards the inner area of the film had not been good enough.

I was using a Paterson tank but using the stirring tool. 10 secs of slow spinning every 60 secs.

I'll go back to inverting.

Stirring has worked well for me.
Spin the tool with some attitude both clockwise and counter clockwise.
Gentle is for the uh .. other dark room Wink

I used the camera again and processed a film without these problems occuring but used inversions instead. I probably was not using enough force when stirring.
