The Fixer Leader Test, Explained
The fixer leader test is ten seconds of honesty: clear a film clip, double the time, and the bath's whole story is told.
The chemistry desk. Developer choice and dilution, stop bath and fixer capacity, agitation rhythm, temperature control, enlarger alignment, dodging and burning, and washing fiber prints properly. Covers both bathroom setups and dedicated rooms. Intended for anyone processing negatives or making prints without a commercial lab.

The fixer leader test is ten seconds of honesty: clear a film clip, double the time, and the bath's whole story is told.

E-6 home development is six warm baths in a fixed order — and the first developer is the only step that forgives nothing.

C-41 home development uses the same tanks and reels as black-and-white — the only new skill is holding 38 °C steady.

A bathroom darkroom setup needs no construction: light-proof the gaps, respect safelight distance, ventilate between sessions, and print.

Stand development turns Rodinal into the most forgiving process in the darkroom: one 1:100 dilution, one hour, and almost no agitation.
