- A powder developer, such as D-76, must be kept from light and air until it is mixed. This means that you must mix the entire envelope at one time. For example you cannot open a package "to make one gallon," extract 1/4 the power, mix one quart, put the remainder back in the package and reseal it. You must "make one gallon" (or whatever).
- #1 is also true for powered fixer and other chemicals.
- Once mixed into a "stock solution" developers must be kept from oxygen but light will not harm them.
- #3 is also true for fixers and hypo-clear.
- Even though tables give developing times for temperatures ranging from 66˚ to 76˚ best results will always be obtained at 68˚.
- Arista Premium film is actually Kodak film.
- Legacy Pro film is actually Fuji Neopan.
- Arista.edu film is actually Fomapan.
- Overexposing film by one stop, then pulling it one stop in processing, will reduce grain, contrast and acutance.
