Aperture & f/stop Tutorial

Aperture & f/stops don't have to be complicated. We start the video by demonstrating what you absolutely must understand: how to change your f/stops to get the most important parts of your picture sharp. For the more advanced photographers, we dig deep into the technical aspects. This video has 12 parts: 1. Aperture & Depth-of-field Essentials (0:35). The most important things you need to know about f/stop: how to get everything in focus. 2. The Focal Plane (2:12). The focal plane is two dimensional, up & down and left & right. Moving forward or back from your focal plane will make a subject increasingly blurry. 3. Exposure & f/stop (3:23). Low f/stop numbers let more light in, while high f/stop numbers let less light in. 4. The Iris & f/stop Numbers (4:03). Low f/stop numbers have a big iris opening, while high f/stop numbers have a small iris opening. 5. f/stop Math (5:00). Tony & Chelsea explain the math behind those strange f/stop numbers. 6. Depth-of-Field (5:40). Some people use depth-of-field calculators, but they're not reliable--and we show you why. 7. Hyperfocal Distance (7:19). Likewise, hyperfocal distance doesn't necessarily work as you might expect. 8. Background Blur (8:00). Low f/stop numbers blur your background. 9. Sharpness & The Sweet Spot (8:43). Your lens is the sharpest at low or moderate f/stop numbers. We show you how to find your sweet spot. 10. Chromatic Aberration (10:11). At low f/stop numbers, you might get purple or green fringes in high-contrast parts of your picture. Fortunately, that's easy to fix. 11. Vignetting (10:54). At low f/stop numbers, the corners of your pictures will often be darker. It's also easy to fix. 12.
