This fine-grained development increases the sharpness of the film and allows for medium-high contrast images with a wealth of detail in the shadows. 1.0 L Kit – 12 rolls of 135/120 film or 36 sheets of 4×5 (or E.S.) 5.0 L Kit – 60 rolls of 135/120 film or 180 sheets of 4×5 (or E.S.)
This development for special applications with hyper-compensating capabilities maintains the grain size and increases image sharpness. It allows the development of films exposed to different sensitivities (± 2 stops) while maintaining the process time and temperature for all the treated films. It is particularly suitable for the treatment of high film (400 ISO) and very high sensitivity (3200 ISO) or drawing processes. 0.5 L Kit – 6 rolls of 135/120 film or 18 sheets of 4×5 (or E.S.) 1.0 L Kit – 12 rolls of 135/120 film or 36 sheets of 4×5 (or E.S.)
This development keeps the grain size unchanged. It allows you to obtain images with a tanning contrast mask (brown color) that improves the contrast during printing increasing the density of the shadows. 100+100 ml Kit – 20 rolls of 135/120 film or 120 sheets of 4×5 (or E.S.) 500+500 ml Kit – 100 rolls of 135/120 film or 600 sheets of 4×5 (or E.S.)
This development allows to obtain high contrast images and maintains the grain size unchanged, which is emphasized by the increase in sharpness. You can increase the sensitivity of films up to 2 stops without any loss of density in the shadows. 100+100 ml Kit – 10 rolls of 135/120 film or 60 sheets of 4×5 (or E.S.) 500+500 ml Kit – 50 rolls of 135/120 film or 300 sheets of 4×5 (or E.S.)
This development for special applications with hyper-compensating capabilities maintains the grain size and increases image sharpness. It allows you to recover up to 14 contrast zones on high lights without affecting the density of shadows. 1.0 L Kit - ONE-SHOT 4 rolls (135/120) or 18 sheets 4×5 (or E.S.)
This inversion chemistry allows you to obtain excellent results with all photographic films on the market. This inversion chemistry allows you to obtain excellent results with all photographic films on the market. Super-energetic processing is specifically designed to restore the best possible sharpness and tonal range from a photographic medium, reducing grain size and increasing image sharpness. Bleaching with hardener allows you to treat films more safely with less risk of defects. 1.0 L Kit – 20 rolls of 135/120 film or 60 sheets of 4×5 (or E.S.) - 40 8×10 prints ( 2 sqm ) of polythene paper. 5.0 L Kit – 100 rolls of 135/120 film or 300 sheets of 4×5 (or E.S.) - 200 8×10 prints ( 10 sqm ) of polythene paper.
