Imaging for High Dynamic Range
A few months ago, Mandy and I got a dog. Sydney just turned 5 months recently, and we've been so glad that we got her. Read on for a photo of Sydney, and a description of a new digital imaging technique I've been trying out called HDRI.
The technique I used in this photo is called HDRI (High Dynamic Range Imaging), and allows a person to take a few different pictures of the same scene--at different exposure levels--then combine them into one image and generate something called a tone map.
The tone map can then be used, along with the bracketed exposures to produce a vibrant version of the same scene.
HDRI is especially useful for situations when there is bright sky and dark shadows. By combing the different exposures into one image, it's possible to get vivid detail in both the shadows (by using an over-exposed image), as well as the sky (by using an under-exposed image).
If you look at any examples on the web (for example, on Flickr), you'll see some over-saturated images that are unrealistically colorful. It's still a cool effect, however, if used subtly.
