Exactol Lux has a bias to finer grain with rich and subtely graduated tones rather than ultra-definition. It gives high tanning and even greater stain. It offers a single time for almost all types of film, but unlike DiXactol Ultra it can be used with high-speed films like Delta and T-Max 3200. It comes in two 100ml packs (A + B) of concentrate which dilute 1:1:100 with water for a basic capacity of over 30 films. It can be diluted even further for greater sharpness, compensation and economy, and can be used as a two-bath as well.
