Upper Yosemite Falls with star trails. It was shot at the same time the previous picture I uploaded was shot (I set up 2 tripods with 2 cameras.) I shot many frames, but ended up discarding most of them as I failed to recognize condensations that were built up on the lens until much later. I used usable frames (about 25 of them) and masked airplane trails one by one before stacking.
