We visited Crater Lake because it was on our bucket list and I especially wanted to see the lodge. But, as we drove in, I looked at the lake. It was mirror smooth and reflected the rim and Wizard Island perfectly. I took my photos like every other tourist, but was really pleased with the reflection. I used Elements 13 and converted the photo to black and white because I thought it showed off the reflection better. Then I experimented further and used the invert filter and this photo is the result.
