Kodak 指示型停顯液（液態）適用黑白底片與相紙（可調製 8 加侖）

The 1:63 dilution is easy to mix, and the indicator change is clear enough even in dim light. It stopped my film development right on schedule, though I wish the bottle had a smaller pour spout.

The indicator dye is a lifesaver—no more guessing when the bath is spent. Mixed up a gallon for my prints and it stopped development instantly. Exactly what I needed for consistent darkroom work.

This stop bath’s color indicator is a game-changer for my darkroom workflow—no more guessing if the solution is still good. I mixed up my first batch over a month ago, and it’s still clear and working perfectly for multiple film developing sessions. Very pleased.
