    Great. i feel pretty confident about starting now. Will get into it early next week after I've done my tax. I'll use a 2 roll Paterson 600ml tank and work through some 120 from the Diana, some 45 sheets wrapped around the inside of the tank (do this all the time with B&W), and some 35mm. will keep an eye on the results and increase the time slightly if it seems necessary. The Jobo kit gives 3.5 min as the start time for dev so I should be safe to add about the same amounts of time for every 20% of capacity. Thanks for the help, Polyglot.

    Just be aware that the stated capacities of the kits differ, and that their exhaustion rates will likewise not match. So that table of times won't necessarily help you much.

    If you have a densitometer you could put a test-strip in with each batch to track the developer's performance.

    Funnily enough I do have a densitometer but have only used it for B&W film. I will research using it for colour.

    I did some C-41 processing a couple of weeks ago - got through two rolls of 35mm, about eight of 120 and half a dozen sheets of 4x5. By chance I had two very similar exposures of 4x5 so I had one sheet done by a good quality dip and dunk pro lab as a reference for my processing. As can be seen they are close enough to identical. The processing was simple enough, although a bit frantic with the primitive method of temperature stability (hot water in a 20 liter tank.) Looks like I'll be teaming up with a friend to split the cost of a 5L Jobo liquid kit for the next phase.

    The obvious thing to do is to buy a Tetenal kit from Vanbar, however when I spoke to them last week I was told these are out of stock and not expected back for 3 to 6 months. I'm reasonably patient, but that's a long time to wait to see my photos.
    I've tried searching ebay but can't find any local sellers. There is someone in the UK selling it, but the $40 local kit will end up being about $70. Freestyle stock a few C41 devs but all the liquids can't be sent internationally. There is a Unicolor powder kit for $20, but regular shipping is about $40, or there is the FIMS shipping for about $20 but I've heard reports of that taking a couple of months.
    I really didn't think it would be this hard.

    What are people in Australia doing to home process C41? Do you buy a lot of kits when Vanbar do have stock? Is there anywhere else I can buy kits from?
    The other option I'm looking at is to buy individual chemicals from Vanbar. I'm sure this will work, although I would have preferred a kit where everything was in the same amounts. This is what I'm considering - (assuming Vanbar has this in stock of course);
    Kodak -Flex SM Unit Dv 2 ltr $22
    Kodak Flex SM Bleach 2.7 ltr $75
    Kodak +E-6 Fixer & repl > 10lt $6.30
    Kodak Flex SM Final Rinse 1.5 ltr $6.30

    The bleach is pricey, but I suppose it should last a fair while, and the other items seem reasonable.
    I'm looking for advice or comments on this, particularly in regards to someone who want to do this in Australia right now, thanks.
    In future want me to just give you some chemistry to do it?

    Hi Steve - would like to discuss this with you. Perhaps I am now qualified to work as a junior in your lab?

    Is that a more-generally-open offer? I'm pretty sure you could sell 1L to 5L kits to Australians since we're mostly paying +100% of the chemistry costs for couriering from UK/DE.
