Netherlands-based photographer Alícia Rius finds beauty where most of us would find rust, dirt and ugliness. She shoots from the back seat of abandoned cars and captures not only the view through the broken windows but the interesting details of the car itself. Looks very much like HDR photos.

Vegard Brenna over at Luminous Landscape has an interesting article on creating an HDR workflow to increase the dynamic range of pictures, in his case, the interiors of Churches. But he wants to avoid the high toned “HDR Effect” that is so popular with some. He shows how to calibrate Photomatix and how to create a “HDR Slider” in Photoshop to automate the creation of HDR images.

How do you expose for the shuttle leaving its launch pad? NASA uses 6 cameras shooting at 250fps, each exposing for different parts of the scene. To make this video, the imaging experts at NASA’s Ames Research Center merged nearly 20,000 photographs taken from 7 seconds before takeoff to 6 seconds after Endeavour left the launch pad.
The use of HDR here goes beyond nice photographs:
This technique can help visualize debris falling during a launch or support research involving intense light sources like rocket engines, plasma experiments and hypersonic vehicle engines.
Here’s a side-by-side comparison showing a one-camera view of the launch and the six-camera composited view:

Scott Kelby shares a simple tip on how to shoot long exposure [HDR] shots without camera shake:
From WeeklyPhotoTips
When shooting High Dynamic Range (HDR) photos, the photographer must bracket the pictures. “Bracket” is just a fancy technical term which means that you take the same shot with different exposures: typically, one exposure as measured by the camera’s meter (mid tones); a second underexposed to capture detail in the highlights (high tones); and a third overexposed to bring out the detail in the shadows (low tones). Since one picture rarely has the capability to retain detail in the high, mid and low tones, we bracket and then combine the three pictures into one in post processing to obtain a HDR picture.
Depending on the complexity of the lighting situation of your scene, you may choose to take even more than 3 photos, varying the amount of over and under exposure in each photo. You can use the Auto Exposure Bracketing (AEB) function or manually dial in a positive or negative exposure using the exposure compensation function of your camera. Some cameras allow only 3 AEB shots; others 5 or more, and you may be able to specify 1/3 EV, 2/3EV or 1EV (or even finer intervals) over/under exposure with each shot.
The question then becomes, How much do I need to bracket? How much over and how much under exposure? The quick answer is to make sure you’ve obtained all the tonal information present in the scene.
Brian Matiash answers this question in more detail in an excellent article on LensProToGoBlog.
Using High Dynamic Range (HDR) technique can dramatically improve your real estate photography. But how much is just right? This excellent video gives examples of the good, the bad and the ugly of HDR photography:
Notice how turning on the lights in the indoors shots make such a great difference.
After you’ve seen these without and with HDR images, don’t you want to take all your pictures with HDR from now on? Just make sure you don’t overdo it.

Black Star Rising poses an important question: “Is HDR Imaging Ethical for Photojournalists?” Note that this question applies specifically to photojournalists, not to artists and amateur photographers, who couldn’t care less.
Most news outlets have a code of ethics that will not allow images to be manipulated in any way. The New York Times specifically forbids HDR imaging in news coverage.
Which goes to show how people do not understand what type of HDR is OK and what type isn’t. This is a controversial issue but I am going to take a stab at it.
