RE: Potentially stupid pt/pd question

I did.  There isn't any visible fog on the test print.  Paper white on the
step wedge matches (visibly, at least) paper white where the paper wasn't

I'm fairly sure it's something in the developer and not my ferric because
I just used it on the sample you sent me the day before.
