Acufine Diafine Powder Film Developer Reviews

Long lasting, wide temperature range

Reasonably economical because it is so long-lasting. A great developer for all types of B&W films. I like that I can use it even in the summer when water temps in the house can exceed 70F. Remarkable acutance, gives an excellent, gritty grain on classic films if used at higher temps. Check MSDS for septic systems.

Absolutely by far the best developer I have ever used. I have developed a vast amount of film in my life, both for myself and clients. Once I started using this, I never went back to anything else. The tonal range of negatives is completely astounding. A project I worked on required the use of Ilford Pan-F 50, about 1,500 rolls, the photographer used a deep red filter and a polarizer to make his exposures and rated the film at 50. By using Diafine exclusively I was able to maintain full highlight and full shadow detail consistently over 1,500 rolls, even in extremely contrasty situations and over & under exposed negatives. The system I use to develop is to make two 1L bottles for A and B, for active and backup solutions. After about 125 rolls dump 250ml from each A and B active bottles and top up the extra 250ml with fresh solution from the backup bottles. Over time, the silver density of the chemical, enriches the tonality in the negatives for darkroom printing however, if you are scanning the process is more difficult when using this method as the density of the negative is increased. So scanning as flat as possible doesn't benefit you and an increased tonal curve in your scanning software in required. I have used nearly every kind of developer and made my own mixes etc, but Diafine is pure magic.

The best thing about Diafine is that you just keep using it. The volume of bottle A goes down slightly each time you use it, so you have to replentish it eventually when the A volume is too small to submerge the film. That's probably after 30 or 40 rolls in a 2-roll tank. shelf life is over a year.
