ARS-IMAGO MB MONOBATH is a highly concentrated all-in-one developer for black and white films. The solution develops and fixes at the same time with only one bath. The negatives have medium-high contrast with a good and balanced tone scale.
Mix Part A with Part B to prepare the working solution which can be reused several times within two months. The stock solution can be also diluted 1:1 and used as one shot developer.
The best results are achived with standard cubic-grain films like lford Hp5 and Fp4, Kodak Tri-x, Rollei RPX, Fomapan or Kentmere. The use with T-Grain films like Ilford Delta or Kodak T-Max is not recommended.
ars-imago MB Monobath is an easy, fast and efficient solution to develop and fix black and white films at the same time with only one chemical bath.
