น้ำยาพัฒนา Color Print RT แบบเติมเข้มข้น สำหรับทำ 4 x 10 ลิตร (40 ลิตร)

Mixing up all four boxes took about an hour, but the 40-liter total means I won't have to reorder for months. The lower replenishment rate has genuinely cut my chemistry costs per print.

Three jugs of this sitting in my darkroom sink and the replenishment math finally makes sense—40 liters from one kit is a steal for a busy lab. Mixed exactly to spec and the developer holds its activity through a full day of prints without drift, which has cut my chemistry waste by a lot. Only gripe

The lower replenishment rate is the real win here — I’m burning through less chemistry per print run than I did with my old setup, and the 40-liter yield stretches my budget nicely. Color balance has stayed dead consistent since I mixed it up.
