Why stand development is not magic
Stand development gets described as a cure for every exposure mistake. It is not. Leaving a dilute developer alone for an hour lets the highlights exhaust their local supply while the shadows keep working, which compresses contrast and sharpens edges a little.
The price is grain. A frame developed for sixty minutes at twenty degrees looks pleasant at normal viewing distance. Enlarged, the clumps are easy to see.
If you try this, agitate gently for the first minute, then leave the tank alone. Bromide drag along the sprocket holes is the usual sign that the tank was left too long or the developer was too weak.
