So I'm thinking of a good way to test my bottle of TCB developer, I grab my TLR and a roll of Shanghai GP3 to get this:
This is Shanghai GP3 @ EI 400, in TCB with minimal agitation (5 min pre-wet, 60 sec initial inversions, 10 sec inversions at 60 min) for 120 mins. It's scanned on a Nikon Coolscan 9000 as 16-bit TIFF grayscale with no adjustments except for re-size and JPEG conversion. The streaks are my fault due to soft emulsion and a self-induced "processing error" ;-) About the mess ... one word ... kids! I figured that since p-aminophenol is also the developing agent in Rodinal that extended stand development might work here too and it did.
