Written down because every roll I develop teaches me something I forget
by the next one.
Stand development
Highly diluted developer, one agitation at the start, then an hour of
nothing. Forgiving with mixed exposures on the same roll, which is most
of my rolls. The edges go soft if the tank is underfilled.
Sleeving
Strips of six into polyethylene, never PVC — the soft plasticiser
migrates into the emulsion and shows up years later as a haze nobody
can clean off.
Base fog
The density film carries even where no light reached it. Grows with
age and heat, which is why the freezer holds more stock than food.
Reciprocity failure
Past a second or so, film stops answering light proportionally and
needs far more exposure than the meter claims. Each stock fails at its
own rate, so the correction lives on a card in the bag.
