All the other film SLRs have had TTL flash for the last decade or two.

I suggest for flash painting where you run around, that you use Bulb on
the camera, with an assistant covering the lens with a black card
between flashes to minimise ambient effects - especially from that
torch you'll be using to avoid tripping
Expose each flash using the flash's auto setting for the f/stop you're
using. Since these are big places, you have to be careful the f/stop
chosen will allow the flash to reach each painted subject from where
you're flashing. This assumes black areas, or minimal overlaps between
"paintings." For more even overlaps, flash multiple times using a
smaller auto f/stop setting on the flash.
