I have done about 5 rolls of Foma 400 in 35mm. It came out ok for me in D-76 but I left it in HC110 for an extra 30 seconds by mistake and it came out severely overdeveloped. You could barely see through the edges. I even refixed to see if that would help.
I have read that HC110 is not recommended and I won't use it again for Fomapan.
I am at the beginner level and so far have not been happy with Foma 400. Tri-X and Plus-X have been better for me.
