Today, I cut two strips from a test film, and developed one in commercial R09 Rodinal (From MACO Germany). The other was developed in Parodinal Batch 25082012-01:.
The negs are drying as I type, but look almost identical. Scanned results will come later after negs have dried. Any difference will be noticeable in the scan.
