Ethol LPD Powder Developer

Ethol LPD Powder Black & White Paper Developer is a darkroom chemistry product for photographers who print on fibre or resin-coated paper. The powder format yields one gallon of working solution when mixed. It is designed for standard tray processing and replenishment workflows.

360 8x10 prints per half gallon

A half-gallon tray of mixed developer processes a minimum of 360 8x10 single-weight prints before exhaustion. Replenishment extends usable life further for high-volume sessions. Capacity drops with larger print sizes or double-weight stock, requiring more frequent refresh.

Non-toxic powder with tone control

The formula contains no metals and is non-irritating to skin during handling. Dilution adjustments alter image tone without shifting contrast, letting printers match different paper surfaces. Powder storage offers long shelf life compared to liquid concentrates.
