Last night I was trying to find a location where I could position the Coast mountains behind this lighthouse. Then I used my 500mm lens to compress the view of the lighthouse and the mountains behind. I think I experienced some heat shimmer when I took this photo. This is an optical phenomenon that can occur when using telephoto lenses, especially long focal lengths, in hot weather conditions. It’s caused by differences in air temperature and density, which can lead to distortion or a flickering effect on your images. Click on the photo to see a larger version.
