Acufine DFD32 Reviews

Diafine Powder Film Developer (Makes 1 Quart) is rated 4.9 out of 5 by 9.
Rated 5 out of 5 by from Great developer It still exists. It works very well, beautiful results, easy to handle. It is a two bath developer, which means that you have one extra step in your development process. But then, it is extremely flexible. Any temperature between 20 and 30 degrees celsius will do, - of course make sure that all your steps are within a 1 degree tolerance, to avoid damaging the film. Each bath is 3 minutes, but a little longer won't hurt. Development time will remain the same when you push your ISO. One package will do a lot of films - about 60. Also in a solution form you can use it for several years if you don't develop that many films. I never lost a film by using this.

Rated 5 out of 5 by from Foolproof You cant process B&W film any easier with this two-step process. Virtually impossible to mess up. For most films, its 3 min A and 3 min B, although there is extensive information on the Internet per the exact type of film you are using...whether that be from Kodak, Fuji, Foma, etc. Diafine also allows you to easily push film. Unless you are doing a ton of processing, I would go with the quart size, as the stock solution can be used over-and-over again. Some have said it has lasted them one year or more under moderate use. I called the factory and talked with one of their technical people and he suggested that I store the solutions in glass instead of plastic. So, I bought some Ball quart canning jars to hold the two different parts and keep them in total darkness when not in use.

Rated 5 out of 5 by from Excellent for high speed I use this to develop Tri-X exposed at 1600. If you follow the instructions it gives excellent negatives. A note about mixing the chemicals: Make sure you are within the prescribed temperature range, otherwise it will take a long long time for the powders to get completely dissolved.

Rated 5 out of 5 by from Accept no substitutes 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.

Rated 5 out of 5 by from Great for a DIY darkroom Diafine is my favorite film developer. Why? It's simple, really: you don't need to worry your little heart about development time, or even for that matter about temperature! For almost any film you're processing, you soup it for three minutes in bath A, then three minutes in bath B. You can even throw different kinds of film in the same batch; with the exception of a couple of esoteric ones, all films get the same 3+3 treatment. As long as you're get yourself somewhere between 70 and 85, temperature has no effect. Great if you're trying to put together a DIY darkroom in your apartment; no need for tempered water. Another upside: all your films get an ISO push in Diafine. You rate Tri-X at ISO 1600, for example, when processing in Diafine. Ilford Pan-F gets a bump from ISO 50 to 80. The only downside is that, since there's only one developing time and temperature has no effect, you can't push or pull process; you're stuck with the contrast and EI you've got. This is less of a problem if you're scanning your negatives, though; Photoshop is going to give you a far greater degree of contrast control anyway.

Rated 5 out of 5 by from Easy to use when pushing film. I am using Diafine to develop Tri-X when I am pushing film and guessing exposures. Quick, easy and provides usable negatives for scanning.

Rated 5 out of 5 by from Use with Pan X Use to use pan X pushed to 400 and have grainless 11x16 prints that still look perfect, I wish that it was still available
