How to use

To use the Liquid Paper Developer Foma Fomatol LQN 250 ml, prepare your darkroom workspace and ensure proper ventilation and safety gear such as gloves and eye protection. Dilute the liquid concentrate with water strictly following the dilution ratios and temperature guidelines specified on the product label by the manufacturer. Measure the required amount of concentrate and mix it thoroughly with water in a clean processing tray. Submerge your exposed black-and-white photographic paper or contact print material into the developer bath for the recommended duration, agitating the tray continuously for even development. Transfer the paper to a stop bath immediately once development is complete to halt the chemical reaction before moving the material to the fixer.
