Human eyes are incredible for viewing the world and seeing into shadows and highlights all at the same time.

We call it “bracketing” or “shooting for HDR” or “shooting brackets.” Every interchangeable-lens camera I’ve seen for sale in the last seven years offers automatic bracketing, but … [Read more...] about HDR 101: Shooting Brackets

A properly exposed image is created by mixing three key elements, known as the Exposure Triangle—Aperture, Shutter Speed and ISO—to produce the right amount of lightness and darkness for a photograph. There are almost endless combinations that can be used to achieve an equivalent exposure. Leaving your camera in full auto mode will usually guarantee a perfect exposure, but not necessarily a perfect image. To be creative, a photographer decides how much of each element’s value to use based on the element’s … [Read more...] about Understanding Equivalent Exposure Pay attention – there’s a Quiz

They contract to a smaller size reducing the amount of light in bright places. The aperture (also known as the f/stop) in a lens does the same thing. Of course, there's a lot more to it.The aperture not only controls exposure, it is a creative tool too. Want the background out of focus? Choose the right aperture. Need things sharp front to back? There's an aperture for that. Bokeh? Yep. It's all about the … [Read more...] about Photography’s Basics: Aperture
