    planning the wetside

    Dear APUG Members

    I've got 12ftx8ft of darkroom space at my disposal and I am currently planning the wetside.

    Proposed outcome: 20"x24" colour prints using the tray method only.

    Do I need space for 3 trays (as with b&w)?
    Has anyone who built their own sink got any advice?

    Thanks

    Julian

    Hello Julian,

    If you are printing Ilfochromes, 3 steps are required. If you are using process RA-4 for printing color negatives, then a stop bath is optional (Develop > Blix > Wash) per Kodak publication Z130.

    Trays for 20x24 colour prints? Is somebody giving you free chemicals?

    Hi Chad
    I'll be printing from Fujicolor Pro 160S colour negs, onto fujicolour crystal archive paper...so would it then be develop > blix > wash?

    (2 trays, and then onto the print washer)

    Hi Nick
    A 2.5 litre dev kit has the capacity to print approx. 5 square meters, which is the equivalent of about eight 20"x24" sheets of paper. Let's say the kit I have in mind is around £20, that's only £2.50 worth of developer per sheet...which is cheaper than a pint from the local pub. Obviously free chemicals would be nice...but that's not a reality, unless Tetenal wish to sponsor me!

    Any thoughts on the sink? Has anyone built themselves a custom made sink?

    Best

    Julian

    I'm having trouble imagining how much a 20x24 tray uses in chemicals right now but isn't it more then 2.5litres?

    Mmm...I see what you mean. Perhaps 3-4 litres would slosh over the print better - I haven't got the trays yet - so cannot experiment here.

    Yes. One tray for developer and one for the blix, then straight to the print washer. I’ve always used a stop bath since it is supposed to extend the life of the blix. According to the Kodak publication, “Excessive developer carry-over into the bleach-fix can cause
    surface marks or streaks on print.
    ” If you have this problem you would need to add a stop bath OR increase your blix replenishment rates.

    Julian,
    I use 20x24 trays for B&W and 128 oz. of liquid is pretty minimal, and then you have to have the tray pretty level. I use shims to make up for the slope of the sink.
