Kodak Kodachrome 25 vs Kodak Kodachrome 64
Which Kodachrome?
The same photograph, same exposure, both looks at full strength. See the untouched original.
The difference
Kodachrome 25 is the sharper, finer-grained film with denser blacks and marginally more restrained reds — photographers who used it describe a resolution nothing later matched. Kodachrome 64 is two-thirds of a stop faster with slightly more saturated reds, and that practical difference is why it outsold the 25 and became the Kodachrome most people picture.
Which to use
Kodachrome 25
Maximum sharpness and density. The connoisseur's choice.
Kodachrome 64
The iconic one. Warmer reds, more usable, the National Geographic look.
