Its keeps happening and I have no idea. For a while i thought it was not enough developer in the tank, but developing last night proved to me it wasn't.

Here's an example: http://farm3.static.flickr.com/2284/2267528086_1ab2afa408_o.jpg

and the negative looks all brown where that is.... Any ideas????????????

Looks like not enough of something in the tank... You can see the bubbles along the edge. Brown implies developer and/or fixer. How do you -know- you have enough? How do you agitate?

because about 1 liter is enough to fill the tank and i have more developer than that. Maybe i need more fixer, but i think i have plenty. Also when i agitate, i flip it upside down, flip it back, twist it, repeat.

Thanks for the help. Lets solve this!

The film edge is clearly not in chemicals between agitations, there is a harsh line across the negative, the "bubbles" are where the developer is still on the film after and inversion.

Why kind of film, tank, developer?

film is ilford delta 100, not sure what tank but its pretty big and can almost fit 120 reels,and im using ifosol s. Im using a liter of developer!

An easy check is to put and empty reel in the tank, and then fill it with water until the reel is completely submerged. then just pour out the water to see how much chem you need. At each step to be sure to use at least that amount.

What do you do to stop development? Perhaps your stop solution (be it an actual stopper or a water stop) does not cover the film entirely, which would allow development to continue in that area (hence the lighter appearance of the image on that side).

The other thing could be that your fixer does not completely cover the film. The fact that it is brownish in color seems to indicate that the fixer did not remove all of the anti-halation layer or undeveloped emulsion in that area.

Just to confirm, this is 120 Ilford Delta, as seen in your other post.

yep 120, and my stop bath could be a little weak. I haven't diluted it for a while! And there's plenty of it, a tad over a liter. And i just rediluted my fixer and i have plenty of it.

David Dorcich , Feb 15, 2008; 02:21 p.m.

You said that the tank can "almost" fit a 120 reel. How are you loading the film into the tank then?

Probably need two reels.
