BKA Diafine powder film developer to make 2 gallons

Diafine is an extremely durable, two-bath ultra-fine grain film developer with high speed yield. Diafine can be used in a wide range of temperatures with a uniform development time for films with differing sensitivities. Diafine lets you develop films with different sensitivities together, without adjusting the development time. This film developer is unsurpassed for speed yield. The development yields negatives which have ultra-fine grain, maximum sharpness and optimal resolution. Varying processing times and temperatures hardly have an effect, as long as the simple fundamental recommendations are adhered to.
