Re: Hello!

yep...on the alt process list now...had to quit
another yahoo group to do so (wasn't getting as much
as i'd hoped)...bleach is easy enough to get, i'll
check the pharmacy for the peroxide...got a couple
more prints done today, didn't come out too bad...one
that i'll submit for the PF's gallery next week is of
"The Monastery" in Petra...came out with fantastic
midtones...also, this holiday break (a perk for us
teachers) i'll have the ability to work on gum
bichromates...
