Everyone in photography has an opinion when the word HDR is mentioned. Sometimes it is all about perceptions or misconceptions. In this blog post, I'm hoping to change your mind or your thought process a little, when you hear the term HDR.
When I started out in photography shooting slide film, I was trained to carry two "mandatory" filters: a polarizer and a set of graduated neutral density filters (ND-grads). Polarizing filters not only increase contrast in skies, but they are indispensible in removing glare and reflections from water and foliage. ND-grad filters offer a way of compressing tones in scenes with a large dynamic range.
One of the limitations of today's digital cameras is that they cannot capture the dynamic range of the human eye. Indeed, our eyes are very sensative organs and have much more latitude than an imaging sensor. Back in the film days, we used to dodge and burn accordingly to get what we wanted. But these days, we just create a High Dynamic Range (HDR) photo. In the video below, the experts over at Kelby Training give us an intro to this process and show us how it can be useful in practical situations.

Outdoor photographers are trained to recognize good light. For most situations, this means the “golden times” right after sunrise and before sunset, and sometimes the pastel light just before dawn and at dusk. Of course, depending on your latitude, the “golden hour” can sometimes be more like the “golden ten minutes.” Other times, sunrises and sunsets just don’t happen. Clouds in the wrong place on the horizon can kill your chance at amazing light, and weather conditions are often unpredictable, as my students discovered a few weeks ago in South Dakota, where we got fogged in until after 10AM one day.
Have you heard about creating an HDR image with a single exposure? In this quick video, Cory Barker from Kelby Training demonstrates the HDR toning feature in Adobe Photoshop CS5 to, "Grunge up" a photo. HDR toning allows you to simulate different effects by tweaking particular areas of the image such as the highlights, shadows, etc. Your creativity won't stop there though: Cory will also show you how to add editable smart filters to the image to turn it into your very own piece of art.
High-dynamic range imaging (HDR) is the fastest growing and perhaps the trendiest new technique in photography. By combining several images with different exposures the photographer can capture scenes which are beyond the dynamic range of their camera. The trick is that HDR scenes not only can't be captured in a single image, they also can't be fully displayed or printed in their native form. That means additional processing is required to turn the photo into one which can be used.
Landscape photographers often find themselves in challenging light. If you're at all experienced with shooting landscapes, then you know that the best light happens in the hour or so right around sunrise and sunset. The so-called "golden hour" is when we get nice, warm light and excellent opportunities for side-lighting to bring out the texture in terrain. If you shoot right around sunrise and sunset, though, you'll also get the problem of too much dynamic range.
