    Uneven Tray Development or Light leak?

    Hey Guys,

    I'm slowly developing film from my trip overseas. So far 2 of 8 sheets have the exact same black mark and they were both in the same holder. This is 16x20" film developed in a 20x24" tray. This camera and holders are brand new to me from Chamonix, and unfortunately I did not test them before I left. I have a total of 3 holders... Hopefully no more suprises. I'm hoping this is just uneven development but again I'm using a 20x24 inch tray so edge unevenness shouldn't be a problem. What do you think?Click image for larger version.

    And here's a closer look. It doesn't start exactly on the edge..Click image for larger version.

    You're not giving us very clear views, all of them have windows, color backgrounds, liquids, etc competing for attention.

    But it isn't light leaks, thats for sure. What kind of film and what are you developing in? First and second pic looks like contamination to me.

    Obviously development can't make the film black unless it is exposed to light first. Either the film holders, the camera or the area between them leak light. It is coming from the side near the darkslide slot. Was the film holder pushed in all the way and engaged properly.

    Took me a while to see what you are referring to. Did you remove the dark slide completely out of the film holder ?
    If you pulled the dark slide out and let it rest in the slot you may have caused a light leak, the dark edge is angled.

    And I must say that's a huge sheet of film !

    Thanks for the quick responses. I'll post another photo once the film dries. I always pull the dark slide completely out of the holder before making an exposure. And yes, the holder was definitely fully inserted into the camera. The dark area is where the slot for the dark slide is located. This is FP4+ developed in HC-110. I should also mention I've never had any issues with my 8x10 for 6 years, so it's probably not user error. I just wanted to make sure it wasn't simply uneven development before I waste more film to figure out which holder has the issue.

    Ok, the film is dry and here it is. I still feel that it might be uneven development on the edges, at least I hope that's what it is. The other 4 sheets I've developed have been nice and even. These sheets were in the same holder back to back.

    Thats a light leak. Hell I didnt even see that the other pictures had so much wrong with them. New holders shouldnt leak if they are loaded properly, so maybe it isn't seating properly in the back.
