On this particular night a misty somewhat low fog was hovering around the towers of the Bay Bridge. I had been out there many times before, but never experienced this effect. So dreamy to see, I was awestruck by it's beauty. While post processing in RAW, I decided to try several different toning approaches. The blue was the result of playing with the Camera Calibration tab and the Split Toning tabs. I tried both a warm peach color and a cool blue color. Ultimately the blue was my favorite!
