If you recently upgraded from a compact camera to a DSLR, one of the first things you probably noticed was that focusing is done completely differently. Instead of simply pointing your camera at a subject and letting the camera figure out what to do, you now need to think about autofocus points, which often don’t seem as “intelligent” as the focus systems in point-and-shoot cameras. The truth is, autofocus points are extremely powerful and give you a great deal more freedom — you just need to know how to use them.
To get you started, here’s a great primer video by photographer Phil Steele. Over the course of 9 minutes, Steele steps through five fundamental tips for achieving fine focus and tack-sharp photos: ditching full auto, focus and recomposing, looking for edge contrasts, using manual pre-focusing, and making use of live view to aid in manual focusing.
Photography instructor Mike Browne of PhotographyCourses.Biz has a clever way of teaching the basic principles of flash photography. He uses water from an ordinary garden hose as an analogy for light, showing different ways you can go about soaking your portrait subject. Read more…
Here’s a talk Photoshop guru Scott Kelby gave at the recent Google+ Photography Conference on how to “crush the composition”. It’s a talk that goes beyond the basics of rules of thirds, leading lines, and repeating patterns.
Here’s a 10 minute photography lesson by Karl Taylor on the four main types of light: transmitted, reflected, soft, and hard. Understanding these concepts can revolutionize the way you see and shoot scenes.
Digital camera sensors come in two flavors, charge couple device (CCD) sensors and complementary metal–oxide–semiconductor (CMOS) sensors. In this video, Bill Hammack the Engineer Guy offers a short explanation of how CCD sensors capture and store images, and how a color filter array is used to capture color photos.
Bart Zoni of Leica Boss made this short video explaining the main differences between DSLR and mirrorless cameras. He discusses flange focal distance and sensor size, and how the cameras’ differences in those two things affect image quality.
