Hi,
Today I tried tray developing more than one sheet at a time, shuffling the negatives. Since it's the first time I've done it, I'm guessing that development is somehow the problem.
So the negatives, on the whole, look good and evenly developed. I just made contact sheets, and noticed on one of them a black hole... it looks slmost exactly like a light source, except in reverse. On the negative, it's a small clear area. It doesn't have any defined edge, but gradually fades back to the surrounding image. It's maybe 3-4mm large on the negative / contact.
Has this happened to anyone else? What did I do wrong? If it matters, I'm using 4x5 HP5+, HC-110 dilution "H" for about 12 minutes. I processed 8 sheets and only one of them had a problem.
Thanks!
