C-41

You need the following. This is exactly what I use, but if I was you I would get it all from http://www.pakor.com/category/C41_Chemistry.cfm since you will be needing a lot. The only thing difficult to find is the bleach. The Trebla bleach works fine.

Wow. That is still an expensive project. Here in the UK 300 sheets would be knocking on for £900, possibly £800 with a bargained discount.
How do you plan to finally display these pics?

Framed 20x30 most likely, with the handwritten element displayed 8x10ish below the image. I won't show all 100 at one time... The school's gallery is WHAY to small, but I do want to shoot that volume of subjects to have the diversity required for my project. It'll be expensive, but senior project are usually expensive.

You may want to check out the Rollei Digibase C-41 chemistry newly available from Freestyle. Excellent price, capacity, shelf life, etc...

I have not used this yet, but I like that it features a separate bleach and fixer.

There is a lengthy thread on APUG: http://www.apug.org/forums/forum40/7...se-c-41-a.html

I'll second the Rollei Digibase idea. Some people report an amazing capacity of working solutions. I've some on order to do a bit of a test.

Okay after some research about the Digibase I think I'm going to go that route to begin with... my followup question is, where should I order it in the US? Freestyle only has the 20 Roll kit, and figuring that 1 4x5 sheet = 1 roll then I'd realistically use up that entire kit after two batches in my 3010 Expert drum right? Do they make a larger kit that would last me longer than two batches?? Or should I order five of these suckers?

No, 4 sheets equals 1 roll approx....80 square inches.

So, 4 sheets of 4x5 is equal to a roll? So the 20 Roll kit would accommodate 80 sheets?

Hey guys,

New user here, I am about to begin a project in C-41 4x5 and would like to do most of the developing at home... I recently bought a barely used Jobo CPA-2 with various drums and reels including the expert drum that accommodates the 4x5 sheets. I guess I am simply looking for some general information about what else I'll need... And some recommendations as to what chemical to use, and drying techniques etc... I appreciate the help in advance!

Do you have a Jobo manual? It would answer many of your questions.

I think I've had most of my questions answered however the Jobo manual doesn't address selection of chemicals or drying techniques. Thanks though.

Since Kodak has juggled their chemistry around, I have only been able to find the Developer/Replenisher, not the plain developer.

I have looked at the Developer/Replenisher and Developer Starter on these same sites and they mention that one must be used with the other. Is this true? Then I will have to buy some starter to go with the replenisher.

Investigation of the Kodak site makes no mention as to how this chemistry is to be mixed. In fact most of the C-41 data notes are 5 or 6 years out of date.

Can anyone tell me if it is necessary to mix the starter with the replenisher for one shot processing and if so, in what proportions?

I am getting to the end of my straight developer and will have to have a go with the replenisher/starter. As soon as I finish the Kodak chemicals I have in stock, I will be moving on to the C-41 kits that Freestyle offers.

The price I am paying for 2.7 liters of bleach is now $47 from Denver Pro Photo. (I know it is cheaper from the New York houses, but they won't ship.) That is a jump from the $29/gallon that I paid previously.

As soon as I finish off the Kodak chemicals I have in house ... no more!
