Tetenal Ultrafin is a liquid, one-shot black-and-white film developer suitable for the development of nearly every black-and-white negative film. Ultrafin has been on the market for many years now and has become one of those classic film developers that can still amaze analog photographers.
One of the main benefits of Ultrafin is that it is a true universal film developer which produces an excellent speed yield, fine grain, great resolution and nice overall contrast with nearly every existing film today.
The contrast of the negatives can easily be controlled by adjusting the used dilution which is possible from 1+10 to 1+30. This bottle of 1L will allow you to develop approximately 80 35mm films.
