"Hope this helps, OTOH, a couple of the prints looked fine to me......"
These are scans from the negative, not prints, it was easier to handle the contrast with Photoshop... the variations are a leftover from a short critique round regarding "how would you crop it".
Tonight IŽll try another pre-flash + splitgrade, if failing IŽll give the Sterry method a try - donŽt have ferricyanid at hand at the moment (but the latest "raw stuff" order already arrived at a friend of mine), IŽll use a very dilute stock of bleach I already have set up at hand from a Sepia toning kit ("Classic"/Foma). Bleach is bleach.
Thanks guys. IŽll come back with either failure or success. ;-)
