dark film along sprocket holes

[mllanos1111]

I just processed a roll of Tri-X and this is also with a new batch of ID11.
This is the first time i've seen this but some parts of the negatives along the sprocket holes and about 2-3 frames long are dark.
The film is still drying so I'm not sure if this may be uneven developing or something else.
Have you ever seen this?
It looks like the images should be fine, but I wont know untill I print them.

Thanks

I believe I have heard it could be from over agitation.

i get the same thing with tri-x and only tri-x i thought i had a minor light leak ( i roll my own film ) in a film canister . could be agitation i don't know so far it has not crept into the image at all just along the sprockets .

Yes at first I thought it was a light leak too, but I dont think so anymore.
I dont think it has crept into the image as well either, but it's a little disturbing.
I've been processing and agitating the same way every time, so I guess I will just have to keep a close eye on future rolls to be sure.

I get dark sprocket holes a lot. Might be from crimping the film while loading. It has never amounted to anything.

I just printed some of the negs and they look to be good. It looks like the darkening along the side did not creep into the image. 🙂
I started rating the Tri-X at iso 320 and it seems from what I can tell so far that I am getting a little better midtones from the couple images I made.

There is something up with Tri-X and this, I've had some students have this same thing happen with Tri-X and only Tri-X. As well, there was a batch of Tri-X with all kinds of wierd emulsion defects- like giant airbells almost about a year ago.

I occasionally get thin marks where the film hits the metal reel and prevents chemistry from getting there, but these are short, perhaps 1/2" and very thin, between the sprocket holes and the edge of the film.

Funny you should mention this, I was looking at some of my tri-x stuff from highschool and I have the same thing present.

Yes something is odd with Tri-X I also had two frame where the emulsion is thin between them.

That I'd call Kodak about, you could likely get the film replaced- marking on the edges doesn't bother me, but if there is a bad image due to film it should be replaced.

These are commonly known to lab rats as "surge marks". Usually overagitation in the beginning of processing. Did it occur in frames with high density (like lots of white space -- eg, skies?)

I had what you described with Tri-X in the past but I found fresh Fix takes care of that. I find while I love the film, it does tend to be a dust magnet, even with the photoflo bath at the end.
