This looks like a lot of fun. Thanks for making this happen. My photo was taken in October 2023 on a rafting trip on the Colorado River through the length of the Grand Canyon. I took it with my “land” travel camera – a Canon 90D (APS-C sensor) with a Tamron 18-400 mm zoom. The photo was taken at sunrise with the zoom set at 20 mm; ISO 400, f/20 and 1/1000 sec. My goal was to capture a sunburst (hence the high f-stop) with the dark mountains framing the backlit vegetation and sandy ground. I re-edited the photo using the newly available landscape masks in LRC.
