4. Is the paper just fogged maybe or did they sit around too long prior to being developed?

I've waited as long as a week without any problem.

VTH, it sounds as though your fixer is shot. I've taught pinhole photography classes to kids and adults using Direct Positive Paper and have not had any yellowing problems. I do insist on a full 5-minute fixing time in plenty of fresh fixer. I have quite a bit of the "old" emulsion in my personal stash and have had no trouble with it, either.

Thank you all for your replies. I was wondering about the fixer. The liter I used was from a new bottle and had only fixed four 4x5 sheets and one 35mm roll prior to these prints.

I will try again with a different developer and ensure that I use fresh fixer for sufficient period of time. I think I'm going to try Liquidol and TP-4 this time around.
