[/caption] Crater lake offers so many different shades of blue that you can almost see the color of the lake turn to different shades of blue as you hike along the rim. The time of day, season and direction that you are facing is the major factor in the changing of the blueness of the lake. I took this shot back on 6/30/10 and the time of day was 4:00pm. I was facing towards the west so the sun was at about a 90 degree angle on my left. My position helped bring out the amazing blue color of the lake. I made sure to include some of the snow in the foreground in order to highlight the trees. I was using my Canon T1i along with my Tokina 12-24mm wide angle lens. I had the focal length at 13mm in order to get the most panoramic photo that I could. The camera mode was in Program/Normal so the aperture was at F-5.6 and the shutter as 1/60 second. I set the ISO to 100 in order to ensure that the sensor captured the best light and set the white balance to -0.3 due to the intense glare from the lake, sky and snow. I made sure to attach my CIR-PL and my warming filter.
