    I would like to know what causes the blotches on my negatives.

    The first picture of headstones was taken a I was restoring the camera and learning many of the errors of view camera photograph.

    I tray developed this negative and as you can see, there is considerable number of dark areas.

    The second photo of my back yard is more recent and developed in a developing tank. It still shows the dark areas.

    So, my question is. Is this figure prints, lack of fixer time, light leaks, or some other gremlin?

    The first one that was tray developed to me looks like streaks from the chemistry; could that be due to mixing the chemistry or not enough agitation/keeping it moving in the developer? Is this on the negative or on a print? The second one to me looks like there was some light leaking, or the exposure was light in the lower corners and might need a little burning in.

    From what I am seeing, there are irregular "scratches" in the images.
    That looks like to me fingerprints from contaminated fingers in the chemicals. ergo: using ones hand to agitate the paper or pick it up.

    Had a similar problem years ago and discovered that my hands had some kind of food grease on them. ruined the prints AND the developer.

    Maybe a combination of things?

    But use tongs... didn't people learn that when they started darkroom work? Maybe not, I did. Bamboo or plastic tongs like other darkroom supplies are inexpensive. If you aren't using tongs, you might want to get away from handling photo chemistry and negatives/prints with your fingers and do that as little as possible.

    What you've posted aren't negatives, they're positives. Did you scan the negs and then reverse them digitally or are those scans of prints?

    These are positives uploaded from GIMP processed scanned negatives. I will try to scan and post the negatives.

    I am thinking maybe finger prints from loading film in a changing bag.
