Hi guys,
I just put together all the things I need to start color development of 4x5 film. I have a Jobo CPP2, a Jobo 3010 drum and a Tetenal C-41 kit, the 5 Liter version.
I want to start developing, but I am a bit confused by conflicting or incomplete specifications in the manuals of the Jobo 3010 and Tetenal C-41.
Tomorrow I will do my first batch of 6 films.
This means, according to the Jobo 3010 specs (http://www.jobo.com/jobo_service_analog/us_analog/instructions/instructions_misc_expert_drums.htm#Detailed%20Tables), that I will need 210 ml of chemicals.
As is done with C-41 processing, I will do the development at 38 degrees Celsius.
However, when I go to the C-41 Tetenal specs (http://www.flickr.com/photos/paulclayton/5171695712/lightbox/), a few problems arise:
1. at page 5, in the lower right corner, the times for 38 degrees are calculated for a quantity of 1000 ml of chemicals, not 210 ml as per Jobo 3010 quantity neccessary for 6 4x5 films.
2. the development times for 1 to 4 films are dev / 3'15" and blix / 4', while for 5 to 8 films they become dev / 3'30" and blix / 6'.
I am not really sure what format these 1 to 4 films or 5 to 8 films are in the first place. Are they 35mm, 120mm, 4x5, 5x7?
From what I have read in the Tetenal specs, extending development times by 15' means pushing the film.
I just want a regular process, but which one will it be?
Please help me out.
Thanks,
Nicolai
