HDR, or high dynamic range, is able to combine several images of one scene into one image to give a much higher level of detail.
Did you ever see a photography of a landscape that seemed to amazingly realistic to be real? By this, we mean a picture with an impressive amount of detail in various aspects, which include the shadows, highlights and midtones.
Although it could be that there were ideal shooting conditions that day, it is much more likely that it is an HDR, or high dynamic range, image. HDR is oftentimes described to layman as seeing more similar to the human eye. HDR imaging will combine numerous images of one scene to try to overcome the limitations of exposure range of regular 1 shot photography. The final resulting image will more than likely have a much more detail in its shadows, highlights and each and every other part of the image in between.
HDR imaging is become much more popular, and there are actually all types of software and websites aimed at this new technology. On Flickr, you will find over 5,100 HDR members, and you can browse about 25,000 HDR images now.
To create your very own HDR pictures, you will need the very popular HDR software from Photomatix, or you can work with the HDR features that are in Photoshop CS2 and also Bridge.
You are making an HDR image by merging numerous exposures of a shot into an HDR source file that has 32 bits. You then tone map the results to provide you with an image in which the light and contrast adjustments are applied to the HDR source image. This would give you a picture with lots of detail all through the tonal range. It will capture highlights and plenty of shadows that could not be visible in a regular LDR shot.
Much depends upon the source images for your HDR shot. But you can achieve some outstanding results with HDR images that have amazing detail.
You need to know that when you are working on HDR images, you are coping with some very big files and a lot of time for processing. You'll want a PC that is fast with lots of RAM.
Doing HDR imaging means you have to use a bunch of files, do a bunch of steps and do a lot of things to the images. A lot of people might find it irritating and confusing but it is well worth it to stick with it. The HDR images at the end can be stunning.
