C-41 Processing -- Development Times -- Mini-lab
I am now working at the "Nations number one pharmacy" in the photo lab.
I usually take my film to Ritz because they do an excellant job. But for under $3.00 I can develop my film w/o getting prints. I'm a little bothered, I clean the machines, do 4 different types of tests and callibrations on our Noritsu... but, you just tape the film to the leader and pop it in the machine, although film is DX-coded these days... the machine doesn't read them (the cannisters hang free)... Every film has a different development time so I'm not really sure if my REALA 100 is going to look any better than a roll of Superia 400. My question is, will this noticeably affect my negatives and is this how it works at a pro lab? I have a darkoom at home and have shot on atleast twenty varieties of b&w film and none of them had the same development times, so just wondering... Thanks, Jeff |

Thanks, Jeff Those tests are to make sure the chemistry you mixed wasn't screwed up. All C41 & E6 films have the same development time for a given time and temperature-for Normal process. Those film processing machines allow for a slow or faster transport time though. These days I imagine that the service tech sent by Noritsu adjust that when needed. Film speed is set by the maker of the film and is not always accurate to the true ISO designation. Minilabs are very different from Pro labs or at least they should be. Changing the transport speed (development time) will affect the film color balance- unless you have a specific reason time (transport speed ) should not be adjusted. -- Reality-Is finding that perfect picture and never looking back. www.gregblankphoto.com |

Using Kodak's chemistry, Fujichrome goes in the 1st devloper longer than other slide films. On a rotary processor, Ektachrome gets 1st dev. for 6:00 @ 38C, while Fujichrome is in for 7:30. C-41 is consistent across films/speeds for any given chemistry. -- Central Maryland Photographer's Guild - http://www.cmpg.org Strange, Geometrical Hinges - http://sgh.rnovak.net |

Yes I stand corrected, however try finding a lab willing to make the correction for Fuijichrome. -- Reality-Is finding that perfect picture and never looking back. www.gregblankphoto.com |
