Which bleach for print redevelopment (lith)?
I was cleaning up my darkroom and almost tossed in the litter bin a bunch of screwed up prints - overexposed and such. Then in the last moment it occurred to me that I might still have some fun with them and try bleaching them and redeveloping them again in lith (or simply bleach and tone).
I have found two basic formulae of the bleach - one is based on copper sulphate, sulphuric acid and sodium chloride (I presume I can't use regular salt since it is iodized...) - the other being the potassium ferrricyanide and potasium bromide formula.
Is any of these two better for this purpose or could I use either of these for my purpose?
