Customer Reviews (4.8 / 5 · 5 reviews)

Lily T. ★★★★★

The variable dilution is a game-changer for fine-tuning negatives—I get beautifully smooth grain at 1+15 for Tri-X. Processing is quick and the results are consistently sharp.

Brian N. ★★★★★

Mixed 1+15 for Tri-X and the grain is practically invisible while contrast stays perfect. The one-shot convenience means I never worry about developer exhaustion mid-session.

Christopher Q. ★★★★★

Finally got the negatives out of the tank and the grain is incredibly fine even at 1+29 dilution. Very easy to mix and use as a one-shot developer for a quick roll of Tri-X.
