So a liter of that replenisher can do about 182 feet of film at roughly 5 ft per roll this is about 36 rolls. To compare the usage rate, you can see that 35mm perforated film needs about 5.5 ml of LORR replenisher per foot of film. So you can look at this as using about 250ml of developer per 'roll.' Now, if you did commercial processing with a 'continuous' machine, you would want to look at Table 2.2 for replenishment rates (they don't use the term 'capacity' per liter, or whatever, anymore, but rather how much replenisher is needed per unit of film). Z-131 has one section that includes rotary processing - see Table 3-6 for 'Capacity of Unreplenished Solutions.' They are explicit that the chemicals should not be reused, and list 'capacity' per liter of developer as roughly 3 or 4 rolls per nominal roll, depending on film type, etc. It's probably way more info then you want, but. This is sort of the 'bible' for C-41 processing. You can get more complete info on the C-41 process by downloading the Z-131 manual, farther down on that page you linked to. So I've been pretty intimately familiar with the chemical/processing aspects of the color neg/paper systems.

Plus doing yearly audits on chemical usage/costs vs material processed. In my case we also oversaw the results of the chem mix operations, specifying the particular chems for various labs, as well as all the chem analysis for regeneration where this was useful. I've spent probably about half of my working life being heavily involved with high-volume processing, mainly overseeing what we call 'process control,' loosely the measurement (and control) of how well the actual processing conforms to standards. No need to read on if you don't really care. Rather than just throw it out there I'm gonna support this in the rest of this post. I know there are a lot of Jobo users here, and they may take issue with such a statement. Very roughly these machines can make your chemical costs 5 to 10 times higher, on a per roll basis, than with a well operated 'continuous' type processing machine. Matt is right as to the reason you don't see rotary processing listed photofinishers with any substantial volume use different kinds of processing machines.Īs to why 'this might be,' well essentially the rotary-style machines are tremendously wasteful with respect to the amount of chemicals used per roll. A very good local store is looking at bringing in a product to sell, but until then–and depending on the quality of the product they get–I might need to bite the bullet and order from an international source.Īny tips or warnings are greatly appreciated and will help me save money and, more importantly, save film! Getting this stuff in NZ is very hard and expensive.

Rollei Digibase Kit (again from Fotoimpex, who I think offer ground shipping only.).

Film Photography Project C41 kit (Cheap, but is it any good?).

Tetenal Colortec (Shipping is limited or prohibited by most places, but I think Fotoimpex can find a way.).

Kodak Flexicolor (massive quantities though, how to partial bottles of the developer keep? Can't imagine getting through 20L very fast unless I bank up film and process in massive batches.).

Most stores will not ship a good portion of chemicals to NZ, but these are some of the options I see that I can perhaps get hold of via 'slow boat' shipping.

The complicating factor is that I live in New Zealand and will have to import my chemical kits. I'm looking to begin processing 8x10' and 4x5' film in expert drums, and I'm wondering if there is a quality and reliability difference between the different brands of chemicals? I know C41 is a standard process, but I have heard anecdotally that some brands are more prone to streaking and other defects and considering the cost and preciousness of 8x10' film I don't want to take any chances. I'm new to C41 processing having just bought a Jobo CPP3.
