Sprint Standard B&W Film Developer

This professional-grade black and white film developer delivers consistent, high-quality results for analogue photographers. The liquid concentrate is free from Metol, reducing the risk of skin irritation during handling. It is designed as a core component of a complete B&W negative processing system for both amateurs and professionals.

Suited for darkroom users who process volume

Photographers developing 50 to 110 rolls per batch will appreciate the economical concentrate ratio and agitation-streak inhibition. Those who only develop occasional single rolls or prefer pre-mixed, single-use chemistry should look at alternative formats. It is not for colour film processing or developers requiring Metol-based formulas.

One litre concentrate yields ten litres working

This volume comfortably handles at least 50 rolls of film in standard use. With replenished solution workflows, capacity extends up to 110 rolls before exhaustion. The formula prevents over-development to preserve highlight detail, but headroom ends when the working solution reaches its roll limit or shows signs of depletion.

Yes, a replenished solution can process up to 110 rolls while maintaining consistent development quality.

How can I verify the concentrate is still active before mixing a fresh batch?

Mix a small test volume and develop a control strip; normal contrast and clear highlights confirm the developer is working as intended.
