Looping Gifs of Supercell Thunderstorms
Mike Hollingshead of Extreme Instability has released an amazing series of 17 HD looping storm gifs at an amazing 1920×1080 resolution. You can check out the full gallery here but be warned, some of the gifs may take a moment to load, with some as large as 20-30 MB.
Hollingshead has a tutorial on how to create these amazing gifs as part of an extensive 8 hour photography tutorial video, which is a culmination of everything he has learned in 13+ years of storm photography. You can find a list of the topics covered in his tutorial video here.
