Tetenal Neofin Blue is a one-shot film developer for black and white negatives with the highest resolution and exceptional sharpness. The film's speed is fully exploited and is best used with slow to medium speed ISO films.
Neofin blue is easy to use and is recommended for the processing of smaller quantities of film. This developer is characterized by outstanding resolving power and exceptional sharpness.
Neofin Blue comes in a box with 6 bottles, each containing 50 ml of concentrate for mixing 300 – 700 ml of working solution:
250 ml water + 50 ml concentrate or
450 ml water + 50 ml concentrate or
650 ml water + 50 ml concentrate.
The choice for a certain dilution depends upon the size of the developer drum and the chosen developing time. A basic rule is: higher dilution = longer time and vice versa.
Most common dilutions are to 300 ml and to 500 ml, while a dilution to 700 ml is possible only with selected films, such as Rollei Retro 80 S, RPX 25, Ortho 25, Superpan 200 and Foma 100, which require a developing time of not more than 10 minutes for the 500 ml dilution.
The developing times for the 700 ml dilution result from multiplying the times for the 500 ml dilution by factor 1,5 (guide value).
