This is a quick post to share a useful resource I discovered online.
I’m a relative beginner in the darkroom, and occasionally I find that my negatives don’t come out perfectly. It can be hard to know why, what you did wrong, and how you can avoid the same mistake in future.
Fortunately, Olympus have a website about photomicrography which includes pictures of commonly-made black & white film processing errors.
It’s already proven useful to me, since a film that I thought had been fogged by stray light, I now know was caused by expired fixer. The new fixer is already in the post.
