Ever wonder what actually happens between the time you press the shutter button on a DSLR and when the image shows up on the LCD screen? Canon made these two videos explaining how their DSLR cameras work and how they use CMOS sensors to turn photons into photos. You’ll probably find this pretty interesting if you’ve never learned about CMOS sensors before. For a more in-depth lesson, check out the sensor tutorial over on Cambridge in Colour.

Have you always wondered how to use the Pen Tool in Photoshop but have never gotten around to learning it? f stoppers published this uber-informative video tutorial by Sean Armenta teaching how it’s used and why it’s a tool that everyone should learn.

External hard drives are a convenient way to store your digital photographs, but they have finite lifetimes and eventually fail. Failing drives have a number of distinctive sounds that can warn you and give you some time to start a data-exodus to a healthier hard drive. Datacent, a data recovery company, has a useful page on which you can listen to some of the most common “bad drive sounds”. These are categorized by manufacturer, and include things like stuck spindles, disk heads crashing, accessing bad sectors, and bad bearings. If your drive makes any of these sounds while your photographs are still accessible, begin evasive maneuversimmediately!

Photographer Mike Collins created this simple video that gives you a visual look at the difference between full frame sensors and crop frame sensors when using the same lens. The video uses a Canon 5D Mark II for the full frame shots, and a Canon 7D (1.6x crop factor) for the crop shots.
This is a short test with the tripod in the same spot switching between prime lenses to show how the crop affects the 7D. The subject, ace stand in Chris Clement, was roughly five feet from the camera. This isn’t meant to be an aesthetic test to show the difference in image quality between the two cameras. It’s a down and dirty field guide for myself and the other shooters we work with so we can quickly figure what lens we want to use on each camera.
We go from 20mm all the way to 100mm with a Lensbaby composer thrown in at the very end.
You might be surprised at how different the lens are, especially if you’ve never used both full frame and crop frame before.
In 1983 the BBC aired a series called “Master Photographers” in which they interviewed some of the biggest names in photography at the time, including Ansel Adams, Diane Arbus, and Henri Cartier-Bresson.

If you’re at all interested in learning how historical greats worked and thought, this is a video series you have to bookmark and chew through.
