[nsmk82]

HI, what is the minimum quality of chemicals need (ml) to develop 8x10 papers in 8x10 tray?

The biggest issue you'll probably have is covering the paper, getting the paper wet and keeping the chemicals moving across the surface.

Depending on the developer you are using, you may be able to use 500ml or a full liter and then at the end save the leftovers and replenish. (When reusing from trays I filter the used developer as it goes back into storage.)

As a rough guide I would not use less than 500 cc, but if I had a more than say 10 prints to do, I would increase that to 1 litre. (assuming you are using a 10x8 dish)

^^^ what he said

500ml will cover an 8" x 10" tray to a depth of about 1cm or a little under 1/2". Its enough with a bit of tray rocking to make sure good coverage. I generally do short printing sessions and this is what I use to not be too wasteful with chems. I use 750-1000ml in 10" x 14" trays. Keep an eye on capacity and this is fine.

If using Ilford Multigrade developer with Resin coated paper, I have found that so long as the print run is not too extended, diluting to 1-14 will suffice, but extend the developing time to 1 min - 1 min 25 secs. If using Fibre based paper then extending the development to a full 2.25 minutes or even 22.5 mins seconds.

I use 1l for 8x10 and 2l for 11x14 and 3l for 16x20but that's just methe short answer is :whatever covers the paper fully without a need to push the print under.

Ralph has the classic answer. I use 1L for 11x14s...but I'm processing only 2 or 3 prints. If you run 1/2 dozen or more fiber 11x14s through 1L you will have consistency issues. Likewise, at higher dilutions you see less consistency with increase print volume. One can adjust development times but subtle changes in contrast start to occur as developer exhausts.

Ha! Trick question. You shouldn't be developing anything 8x10 in an 8x10 tray.

Very true.
