We were just driving down the street when I put on my sunglasses and saw all the refracted light in the clouds. It wasn't near as spectacular when I took my sunglasses off, so we pulled over, I took one pic, wasn't satisfied, took off my sunglasses, put it in front of my lens, and snapped again. Looks like I need a polarizing filter now. This is almost straight out of camera, I only did a little manipulation in Lightroom. Just a touch. This is ten minutes later.
