Not a Prius

This is a great photo. Nice sepia tone, which perfectly fits the subject. Well done.

A technical question; Assuming that PL means polarizer. How do you compensate for the polarizer on the 500CM ?

Rudy, thank you. You're most kind.
I've made *alot* of metering/exposure errors and haven't worked out the finer difference in compensation between low indoor light (the train detail shots) and bright direct sun. The raw scan would indicate this one's pretty close at 2.5 stops over metered value. It was incident metered, as the tractor was in motion.
