I don't expect to rock anyones world with this but just in case someone might be curious I posted this result of an ACROS shot at 25 test.
My black cat (named DMax) lying in blazing July sun on a white window sill.
And the piano which is in a very dark room and is lit by the quartz halogen light that I turned up a bit to hit the white edges of the music books. Same roll of film as the kitty.
