The basic concept of HDR is that you take multiple shots of the same composition at different exposures. Most cameras identify this process as exposure bracketing. The higher-end digital camera models enable you to shoot anywhere from 3-7 photos at rapid succession at different exposure settings. The reason for multiple exposure is to capture all possible range of detail. The lower exposure will capture deep colors, the middle setting will capture the softer tones and the over-exposed will capture intense shadows. Merging them will give you the full range.
Merged images look disappointing at first. That's because screens can't accurately represent the 32 bits/channel range without further processing. Think of the merged image as film negative. Photomatix calls this process Tone Mapping.
Tone mapping reveals the details in highlights and shadows contained in the original HDR image. It converts the HDR image in 32 bits/channel mode into an image in 16 or 8 bits/channel mode that can be saved as a JPEG.
How to do it yourself?
Using a tripod for the captures is recommended to prevent undesired shaky look. One thing to keep in mind is that if the original photos have a tiny bit of noise, when you layer them, you will get 3 times as much noise. I learned this the hard way. Try to snap the pictures at low ISO speeds to prevent noise.
Once you have captured your RAW photos you have to merge them. Photoshop CS4 has an automated script which allows you to do the merge. I find photoshop's HDR capabilities very limited. A better option is Photomatix. For about $99 you get a very nice MAC or PC application that allows you to merge you photos into HDR magic.
I am still playing with the this style of photo composition and don't really have any of my own photography I am proud to show, very soon though.
If you want to get your hands wet with HDR I would recommend downloading a trial of the Photomatix software (all features are enabled, but you will get a watermarked final image). You can use pretty much any camera that shoots RAW and allows for exposure bracketing. A tripod or steady surface is required to achieve best results, especially for night shots where longer exposure is required.
Start off by setting the exposure bracketing setting to +/-1 and adjust from there. I find the best results to start showing up at around +/-2.

The HDR Book $35.99 This is the eBook version of the printed book. HDR photography is one of the most popular styles of digital photography. The ability to turn images from natural scenes to works of art—whether surrealistic or simply enhanced with HDR techniques—is becoming the staple of the photographer and graphic artist. In The HDR Book , HDR and Photoshop Guru Rafael "RC" Concepcion (of The Photoshop Guys) focuses on processing the image, as well as what happens after an image is processed. It's no secret that there's a bit of Photoshop knowledge required to make an HDR image—and work with plug-ins, such as Nik and Photomatix too—and RC doesn't hold anything back to make sure all readers understand what they need to know about everything involved in the post-production process to make a really great HDR image. RC teaches from start to finish what needs to be done in terms of color correction, layer adjustment, sharpening, cloning, special filters, tonemapping, and more. Throughout the The HDR Book, RC also interviews pioneering HDR experts (such as Trey Ratcliff, Moose Peterson, Michael Steighner, and others) sharing their insights and work. The HDR Book will include access to all of the RAW images used in the chapters, in addition to presets for each image (for both Photomatix and Nik HDR Efex Pro). Also included are two video lessons showing the processing of two HDR images from start to finish. With a couple of plug-ins, some technique, and a little bit of Photoshop, all readers will be able to create stunning HDR images! |
