Rodinal Pre-Treat - Portra 400 at ISO 1600
Roll 20141128-01: Kodak Portra 400 Extended ISO: Hybrid Process - Rodinal & Tetenal C41: Nikon FE2: Vidalia High School vs. Greater Atlanta Christian: Note: After experimenting a bit with stand processing B&W film in Rodinal and being very happy with the results using Tri-X at ISO 3200 I thought there may be a way to partially process C41 film to improve the look of the dark areas of underexposed Portra. I asked the question in the APUG forums. One of the members, Athiril a member here too, determined that a 10 minute stand in 1:100 Rodinal would be sufficient to do what I wanted and conducted some of his own testing, the results of which looked much better than a push or straight processing in C41 only. This roll of film was processed using that method: Rodinal at 1:100 for 10 minutes then processed normally in Tetenal C41 chemistry. The 10 minute Rodinal process was at room temperature 72F with an initial 15 second agitation followed by a gentle swirl at 1.5 minutes and at 3 minutes. The rinse was at 102F and was the first pre-heat rinse step required for the Tetenal kit. This is the first roll I’ve process using this method and I am very happy with the results. The dark areas of the scan look much better than a 2 stop + underexposure with just normal or push processing.
