Folks,

I shot a role of Provia indoors, rated 2 stops above its rated speed. The lighting was daylight with no tungsten lighting turned on. When I had it developed a couple of days ago, I got them back with a Magenta cast. I had notified the lab that I had exposed it 2 stops over the rated speed and while the exposure seems to be "spot on", there is a magenta cast on the roll.
I'd like to know if anyone else has experienced this, is it the film, me or the lab?

Thanks in advance!
