Ilford DD-X

Ilford DD-X comes in a one liter bottle and should be mixed 1+4.

So, if I am using a 1000ml Jobo tank, I will have to use 200ml of DD-X and 800ml water, right?

This tank holds either 4 rolls of 35mm or 2 rolls of 120.

Therefore, a bottle of DD-X will develop 20 rolls of 35mm film or 10 rolls of 120, right?

Just checking...

That's correct.
Look at the datasheet of DD-X for more information [page 9]. Here's the link; http://www.ilford.com/html/us_english/pdf/ilfotecd.pdf

that is correct, and the 1+4 solution can be reused once or twice within a few hours.
Look in the side of the bottle.

I'm not a Jobo user, but you might want to check your Jobo Instructions. 1000 ml sounds like a lot of solution in a rotary tank that only holds four 35mm reels. You still have to work within the capacity limits of the developer, of course.

you can also dilute it 1:9

Say what? 1:9 ? Really? Got times?

2 roll of 120 per 1lt ? No 2 120s on each reel = 4 120 per 1lt.

I also don't have the capacity on hand for DD-X, but I think 200ml of concentrate is more than enough for 4 x35mm rolls, so the mixed stock solution probabal has enough capacity to do more than one tank load.

I think it's around about 1l of 1:4 stock solution should be enough for about 10 x 8x10 sheets (so that's 10x 35mm rolls) - but bear in mind that's an average depending on the negative

Use 2x the 1+4 time to start with and adjust by inspecting the negatives.
