Motion picture still photographers are well paid thanks to our IATSE Local 600 union. We get health insurance, 401k, help on down payments for houses, and many other benefits. I am shooting the top teir of low budget films right now (~$10m budget) and made over $3300 last week (five days). I think that's pretty good to consistently bring home on a pretty easy job.
And the pay goes up even higher as the budget of the films you work on goes up.
