Jim,
something about those 4x5 contacts..... Love em! Looking forward to seeing your work again soon!

I'd imagine there is some effect upon development though I'm no scientist.... I should mention I started using 5 grams of Amidol to make 500ml of developer. I did this to compensate for what I viewed as a loss of amidol because I was running the Chinese powder through a coffee filter. Maybe in actuality I'm compensating for the KBR? I'm still using a developing time of 1 minute at room temp. Prints are definitely fully developed and the water bath works as always.

Consistent indeed, though, all my experience thus far has been with the initial test batch.

P.S. I've also been working on a series of 2 1/4 contacts!
