Calbe A49 (Agfa Atomal) Capacity

Hi I bought some Calbe A49 from J and C Photo, because i thought it

would work great with the Efke 100 I have been experimenting with.

My question is what's the capacity of the developer? I am pretty

sure it's not a one shot developer. Any one have any ideas?

I have tried Calbe A49 with Efke 100 in 35mm but I diluted it 1:1

as a one shot. Like Atomal FF there is a big loss of speed when

it is used undiluted. Diluting 1:1 you get better speed, better

sharpness and still retain remarkably fine grain (must be the

ppd). If you were intending to reuse the stock solution I would

expect it to have a capacity similar to that of D76 stock.

Atomal FF ( before it's discontinuance ) came with a replenisher

and with replenishment a 5 litre batch would keep going for

years.

I've used A49 quite a bit, and I find it a good developer for EDU and Classic Pan (Forte) type films. I have only used it a few times as a full strength developer. Usually I dilute 1+1, where I think it's at its best, and then it is a one shot. You can go 1+2 also, for better economy, and the results are similar to 1+1. When I used it as a stock solution, I developed five rolls of 35mm 36 exp, and them disposed of it. It should work for about ten rolls per liter this way, but I had no data at the time, and didn't want to take any chances. Try writing to JandC Photo for stock solution capacities, or just use it 1+1 and you'll always know it's fresh.
