This great DSLR video tutorial from The Slanted Lens touches on a topic that’s always been possible, but as video image quality improves it’s sure to become an increasingly popular request. It’s about pulling still images from videos—which is a great idea in theory, but this video explains why in practice it’s not as useful as you might think. More than that, though, I think this video serves as a great primer about video shutter speeds, how they affect motion, and how that affects the finished look of a video—or a still photo. It all makes perfect sense, when you think about it: slow shutter speeds plus moving subjects create blur. And while blur is usually not helpful in stills, it’s often necessary to convey motion in video. A great tutorial, and a great explanation, all rolled into one.
