Adox Atomal ATM 49 Black and White Film Developer (To Make 5L)

Atomal is very well suited for push-development. In this case an underexposed film is developed for a longer time to adjust the medium gray tones to a normal contrast. The rule of thumb for pushing a film is Plus 1 Stop (e.g. 400 ASA to 800 ASA): Developing time x 1.33 and Plus 2 Stops (e.g. 400 ASA to 1600 ASA): Developing time x 1.77• Universal ultra-fine grain developer for all types of B/W materials with extremely good equalizing and speed utilization of all film types• Very good to push process films• Due to its superior equalizing capacity it can also process hard working film types like ADOX ORTHO 25 yielding negatives which can be printed on a grade 2 paper• Packaged in three individual powder bags, partially vacuum sealed, to mix either 1 Liter or 5 Liters of stock solution• Can be diluted to be used as a one shot developer 1+1 or 1+2• Depending on dilution to process up to 20 films• High speed films (fine grain, very good speed utilization)• Portraits and landscapes if you prefer smooth Gray areas without too much acutance• Universally as a standard for all film types
