This developer is a universal developer? It adapts to any film shot at any speed, regardless of what the dev chart says. Most films look better pushed a little, but you can find the sweet spot with your speed. Best of all you can use this stuff again and again sometimes for over a year. Don't take it off your shelf.

Hands down the easiest and longest lasting developer for BW

Great stuff for developing many films and provides a boost in exposure index for some films like HP5+ and Tri-x. I typically shoot my HP5+ at ISO 800 when I know I will be developing with Diafine and they come out beautiful with strong contrast which scans easily with great results. I do not darkroom print so I can't advise any guidance if Diafine would be a good choice for those doing wet printing or not.

Diafine is easy to use and has a long shelf life . I use it mostly for Kodak TX400 120 film. I'm a fairly light user, and a batch lasts me about three years.

i use diafine to generate pinhole negatives. this is a compensating developer that gives good negatives for scanning with almost any film i choose to use...even mix and match in the same batch. it is not for zone system users. shelf life is forever in my experience. i replace it after a years use even though it is still working. developing times are short....

this is by far the easiest process i've used. I did mix only half the chemicals and hope the dry's store well in airtight sealed containers.

I'm just now getting into LF photography. I developed ilford FP4 + 5x7 sheet film with it and the negative came out perfect. I'm a newby in the darkroom and have no experience with any other developer.

I use this product to process 35mm and medium format film for scanning. I truly appreciate its consistent results across a wide temperature range and the rich tonal value of the resulting negatives.

I used this product for many years. I wanted/needed to shoot 400 film @ 1600 ASA/ISO ... I needed the speed, either for sports or low-light situations. The "regular" (Name Brand) chemicals were more expensive, and also more touchy on temperature control. Dia-Fine has a much broader temperature window, and by storing the product carefully and maintaining the strength ratio of the "A" and "B" solutions by replenishing from the main solution, one batch would last me for 35-150 rolls of film, depending upon my shooting schedules. A SUPERIOR product, that greatly simplified my darkroom chores.

So far I've used Diafine on a few rolls of Tri-X and a roll of Plus-X. This stuff is amazingly hassle-free because it's not too particular about development time and temperature. Consequently it's perfect for someone who is just getting into doing their own development (like me). Versatility comes in the ability to expose Tri-X anywhere from EI 320 (perhaps even lower) to EI 1600 and still produce good shadow and highlight detail (I should note that I put negatives through a film scanner; I don't print them directly). As for Plus-X, the recommended EI in Diafine is 400, but I tried it on a roll exposed at 125 and the results were equally usable. So I can't speak directly to the exposure latitude with Plus-X, but I'm sure it's there. The downside--if you can call it that--is that there's no push- or pull-processing (apart from the fact that Diafine is a "speed enhancing" developer with most films). So if you need to develop beyond the exposure latitude offered by your particular film, you'll want to use a different developer. Overall, Diafine is great stuff and I will likely be using it for 90% of my development needs.

The best developer for B/W-films. Fast, easy to use with fine grain and good contrast. I use Ilford HP5 and Kodak Tmax100 and Tmax400 with this. No problems with temperature, time. It works and works and works .......

I got it about half a year ago. Still have the same 2 bottles, keep reusing them over and over again. It is great that you cannot go wrong and overdevelop. Bad thing, in my view, is that you are always "pushing", it always adds one stop to your film, and sometimes you may not want that. Sometimes you have plenty of light and you just want the smoothest pictures with least amount of grain. For these situations diafine is not perfect.

I started using this great push developer shooting newpaper pics about 15 years ago. Quick and easy, you get a solid, fine-ish grain iso 1250/1600 with Tri-X. Negs are tack-sharp with surprising tonal range. The best thing is you cannot screw up your processing, because temp and time are not super-critical like most other soups. If you love classic available-light photography, give Diafine a try.
