bagginsbill,

Talking about the lights, skycolor, and ground reflection...
For fun, I dug out some of my photos from a trip to Sedona last year. My digital camera has really good color accuracy. I did panoramics too. Maybe this will inspire you for some more lighting ideas? ^^

Also, I'm going to the beach this weekend. I could take some pictures of a Florida beach if you want. I could take a grey photo square and CMKY key too. Let me know.
