كوداك إنديكاتور ستوب باث (سائل) لأفلام وورق الأبيض والأسود (يكفي 8 غالونات)

The liquid concentrate mixes up in seconds, and the color change from yellow to purple is so obvious I never worry about overusing a batch. Eight gallons from one bottle is great value for my darkroom sessions.

The indicator dye is a lifesaver—it’s obvious when the solution’s exhausted, so I don’t have to guess. Mixed up my first batch yesterday and it stopped development dead in its tracks, exactly as expected.

I’ve been using it for a few weeks now and the liquid concentrate makes mixing up a fresh batch effortless—just 1:9 with water. The indicator color shift from purple to yellow is really handy for knowing when to dump it without guessing.
