Turquoise and Ruby
Verity steps into Lake Louise, Banff National Park, Canada, on a cloudy day. The lake really is that color in Spring. I think it has to do with all the limestone in the runoff from the glaciers, but I am not certain of that. Look at the satellite overlay on the map below and to the right and you will see the same color.
Single RAW pseudohdr. Love the lens distortion filter on CS3. Thanks to the person who showed me that.
