[/caption] This may look like an average rock standing in front of a blue sky but it’s actually Crater Lake behind this rock. That’s right! Crater Lake is so brilliantly blue, that it looks like a tropical blue sky. As you hike or scramble along the rocky rim of the Park, you have several opportunities to witness this type of phenomenon. The lake is so blue that it gives an impression of a blue sky and as you move across the rim you can see how the color of the lake will change colors, depending on the time of day or your location. To get the best opportunity, you do need to stand almost directly on the edge of the rim so you want to be careful since it’s pretty easy to lose your footing as you find yourself immersed in the out of body experience. To get this shot I climbed along the rocky rim and perched myself directly above the lake. I was able to get out of my snow shoes in order to climb on the rocks. I pointed my camera at about a 75 degree angle in order to get a good portion of the rock and as much of the lake without having any glare or reflection from the high clouds above. In fact, any clouds above will create a reflection in the lake so you need to look for a spot that’s perfect. I wasn’t using a tripod when I took this photo so I made sure to turn on my IS and keep a steady hand. I attached my CIR-PL and warming filter on my Sigma 17-70mm lens and set the focal length at 42mm. I was worried about camera shake or blur but I was still able to set the ISO at 100 and reduce the white balance at -1. Because I had the camera in normal/program mode the aperture was set at F-5.7 and the shutter speed at 1/128 second. Luckily, the sun was directly behind me and it was late in the morning so the overhead sky had the perfect amount of brightness.
