it is best to do a few tests before you do the real thing
if you can grab a 35mm camera or something smaller
so you can do some iso and developer combination tests.
at one point years ago i tested about 10-15 different papers
to figure out their iso values relative to film, and they varied wildly ...
expired paper can do wonders as a paper negative because the
basefog helps deal with the contrast ... you might not even need
out of the ordinary developers, just regular old paper developer..
you might want to check out the caffenol blog ( http://caffenol.blogspot.com/ )
for some easy recipes ( you just need a scale or some way to measure your ingredients )
if you use caffenol to process your prints ( and no print developer as a pre-bath )
it can take 2x or more the normal development time to get an image on your paper .
( instead of pulling the print at 2 mins, the image appears in 2 mins &c ) ...
good luck !
