OK, I'm back from a crazy day.
I set a custom white balance off of a card, but looking at the back of the camera I was pretty sure I was still getting color variations. Looking at the thumbs as they are downloading, I sure did.
Other than that though, I think the day turned out better for event photos and I did quite a few sittings afterward.
It's been a stressful day though. My wife called about half way through the event and said she thought one of our dogs had a stroke. Turns out not to be anything so serious, but it was tough going for a few hours.
Once I sort through all the pics, I'll post some favorites. I was really impressed by the whole thing.
