A pro lab that is running over 10k a day in film processing requires precise replenishment and process control,
Keeping grey balances is quite a step above hand process at home.

Nothing wrong with doing home process that way, but impossible to make a living with demanding clients who want consistancey and run to run accuracy with their pushes and pulls.

Most of the good E6 labs are going or gone.

Are these home users with their imprecise dev procedures just imbeciles who don't know what good development results should really look like? Are all these pro labs old dinosaurs pursuing a pointlessly optimized procedure with excessive effort? Why is it that I can get E6 kits easier than E6 processing in my home town?
