great topic, you're gonna get a lot of responses for sure.
lots of photography types here
i myself use a canon digital rebel xt mounted with a simple 35-85mm stock lens. i also have a polarize filter as well as a couple different color filters, ie yellow and orange.
as far as white balance for my camera- i have a setting in my camera that allows me to adjust as i feel needed.
so i often bracket 3 settings up and 3 settings down and then go from there.
works fine for me.
good thread for sure!
