Since Barack Obama and his family visited Yellowstone National Park as well, there was just a little too much Secret Service for me and my camera. ;-) So, I decided to continue my photo safari trip to Banff National Park, where I encountered this beautiful, emerald colored lake. Technique: HDRI made using 3 of the 7 exposures (Smart object method) and then processed in PS with Nik Color Efex and curves.
