彩色負片RT沖洗藥水套組（可配製100公升）

After years of fighting with other chemistry that oxidized too fast, this kit's lower replenishment rate is a real game changer for my darkroom budget. A full 100 liters of working solution lasts noticeably longer between top-ups, and the prints come out with that clean, stable color I expect from R

Mixed a full 100 liters without a single glitch, and the lower replenishment rate really stretches each kit further than I expected for the price. Colors came out punchy and consistent across dozens of prints, which is exactly what I need for steady client work.

The replenishment rate on this kit is impressively low, so a single batch stretches way further than I budgeted for. Mixed up my first 100 liters and the RA-4 prints came out clean and consistent every time.
