Darker edges on negative

<p>Hey guys Ive been having a problem with negatives being darker on the edges (lighter in the positive)<br>

see below:<br>

<img src="http://i113.photobucket.com/albums/n238/jimibmx/death-valley001.jpg" alt="" /></p>

<p>Here are my specs:<br>

Tri-X (happens on both 35mm and 120)<br>

Presoak 1-2min (whatever temp its at. not extreme in either way)<br>

Adonal Developer 1:50 13min@68 degrees<br>

agitation: first 1min then every 30sec for the whole 30sec. (180 total flip)<br>

stop: kodak 30sec (whatever temp its at. not extreme in either way)<br>

Fix: Kodafix 8min (whatever temp its at. not extreme in either way)<br>

Hypo: 5min<br>

wash: 10min</p>

<p>I have already re-fixed. Does not eliminate situation.<br>

I can see the edges are darker in the image area of the negative, but do not see anything in the transparent part of the film. This also only occurs to some images on the roll. NOT ALL OF THEM.<br>

If anybody has some ideas on a solution you would be my hero.<br>

Thanks,<br>

<p>Suggestion. Change tanks and reels. I don't know what tanks and reels you are using. Another suggestion Reduce agitation to 30 seconds for the first minute then 10 seconds for every minute after...</p>

<p> My guess is light fog. Inspect the tank and tank lid for cracks, misalignment, etc. Process an unexposed 35mm and 120. Before crackling open the roll, prepare everything in your usual way, turn off the lights and sit still for 20 minutes. This will be time well spent, it will take that long for your eyes to dark adapt. Now look about; I am betting you will see plenty of light leaks. In any event, process the unexposed film to see if it has dark edges. Additionally, If you are using a safelight, don’t.</p>

<p>Too even for a room leak Alan. I see agitation problems.</p>

<p>If you're agitating 30 seconds out of every minute, that's too much, way too close to continuous agitation. Either 5 seconds every 30 seconds, or 10 seconds every 60 seconds. Just 4 or 5 crisp inversions.</p>

<p>Agree John ...</p>

<p>thanks guys.<br>

I thought it might be too much agitation.<br>

i will give it a shot.<br>

Thanks!</p>

<p>Chuckling at giving it a shot and you are using Adinal/Rodinal. :-)</p>

<p>It's a case of over-agitation. My agitation regime is as follows: 6 inversions during the first 30 seconds then one inversion every 30 seconds after that. I give the tank a swift half-turn as it stands on the bench just before the inversion, this is to impart some circular motion to the developer. I also pre-soak. So, in a development time of 13 minutes I would invert the tank only 18 times.<br>

In the example below the slight lightness on the right is due to the large window at the end of the library.</p><div></div>

<p>Already taken care of we all have to find our beat I think the OP was going with Randy Rhoads and maybe needs some Julie Andrews.<br>

<p>I suggest you think about how long it was between exposures in camera. You may have a small light leak on both edges of the back of the camera. I suggest this due to the comment of not having this on all frames. Process tank problems would be present on ALL frames. Not random frames.</p>
