What we did in the day:
Buy at least 100 rolls of the same emulsion batch. Run several test rolls
shooting and viewing in the intended conditions. Examine the results
carefully and expose and filter the rest of the rolls to suit.
Any change in either shooting or viewing conditions, or, a different
emulsion batch requires retesting.
As films age, their colour rendition and speed changes, you can either
expose/filter to suit the film's current specs or wait until it shifts to a
more favourable colour rendition. Freeze Kodachrome to slow the aging
process.
