I have a problem!
Or rather my students have a problem, and I can't figure it out so hence this post....

When printing the emulsion (FOMA's stuff) everything looks good in the developer - and also in the rinse (stop, which is water), but the second it comes in fixer, be it hardening or hardening, the image turns almost totally black....

I don't really get it, as some have this issue - some not. It rarely happens to me.

And today two students made prints - from the same batch of emulsion - same surface - same chemistry... the one got fine looking images - the other the balck "version"...

How can this happen?

Educate me please...
