Description: I reshot some of the images so I could post a full frame version. Also, some of my original data was kind of suspect so I replaced most of them with new images and threw out the bad ones. While this version consists of 2 hours less data overall, the new images I shot and replaced made a noticeable difference. Thanks for looking!
