The last couple of days provided some really spectacular skies with amazing vapor trails and fluffy clouds. So I grabbed a selection of cameras and shot a bunch of timelapse which you can see cobbled together in this clip. I used a Sony PMW-350 and a Canon 350D and 550D. Amazing how well they match after a quick grade. I also included an previously un-used Aurora shot from Iceland at the end. The name of the clip comes from the fact that clouds are made of water vapor and ice crystals.
