Foma Fomadon LQN is a durable, flexible, neutral contrast liquid black and white negative film developer based on phenidone-hydroquinone. Compared to Fomadon LQR, LQN delivers highly neutral contrast negatives in combination with most black and white films and a normal grain. Nevertheless, LQN has been specifically adjusted to the Fomapan 100 and 400 films and uses the true ISO rating of these films. It is designed for manual processing of all black and white films in perforated/roll/sheet form.
Fomadon LQN can be diluted from 1:10 up to 1:14 with water. One unit has the capacity to develop up to 12 perforated films (135-36) or roll films (120), or a corresponding amount of sheet films (up to 30 sheets size 5x7" / 12.7 x 17.8 cm).
