Adox's Atomal 49 is a universal ultra-finegrain developer for all types of B&W films with high contrast-control. We ship it to you in powder form for easy mixing at home and long shelf life (>3 years)

The three packets included contain enough chemicals to process 50 rolls of black-and-white film at 2+1 dilution, or 100 rolls at 1+1 dilution for one-roll developing. This means you can mix the full pack (or a smaller amount) and store in liquid form for up to 6 weeks while developing single rolls as you shoot.

To push your film by one stop increase developing times by x1.33; to push by two stops increase developing times by x1.77

This formulation used to be known as Calbe 49. Also available from our store in 1L quantities.

A Really nice, fine grain developer

I've now developed a couple of rolls of Adox CHS 100 ll and a roll of FP4+ with this developer, and the results are great!
I would however recomend mixing the developer the night before you intend to use it, as I found it doesn't fully disolve that easilly...leave it overnight in a bottle, then give it a real good shake before using for the first time seems to be the best way I would say. The shot of the Drummer is on Adox CHS 100 ll, and the Church Tower is on FP4+. Both were developed in Atomal 49 at Stock

Off to a good start

I've found this powder developer quite easy to use. I'm still working through my first 1 litre mix since I'm using a tube developer for 5 x 4" which only needs 60ml per neg. It has lasted a month so far, but the liquid is looking a bit darker now. Perhaps its time to mix some more, though I haven't seen any change in the results yet. As I've only started film developing recently I don't have any other products for comparison. 8 minutes at 20 deg C seems about right for FOMA 200.

(the next heading should say 'product' rather than 'film').
