Thanx Drew. That'll give me a good start.
We've got 2 days on the Tundra so I'm hoping to have plenty of time to play around a bit with it while I'm there.
I was just worried about the difference in contrast between Churchill and home.
Great shots, by the way.
Thanx again for your help.
I haven't photographed polar bears myself, but from an exposure point of view, there'll be two things you need to watch out for. One is that cameras' metering often try to reduce bright, white snow scenes to a medium grey (ie. under-expose). If this occurs, you can combat this by dialing in some positive Exposure Compensation.
On this other hand, if you overdo the Exp. Comp or it's a sunny day with direct light you need to watch out for blown highlights. If you're getting this, then you need to dial in the direction of negative Exp. Comp.
So before you go, make sure Overexposed Hightlight Alerts are enabled (so they blick when you review), and then familiarise yourself with the process of Exp. Comp. It's possible to lock the Exp.Comp, and you don't want to be in a panic wondering why you now can't adjust it while a bear walks off!
My only other comment would be, don't be afraid of increasing the ISO if the light start to drop. In a choice between ISO noise and camera shake, Photoshop can do a decent job of getting rid of noise, there's not much that can be done about shake blur.
