High Dynamic Range (HDR) / imaging technique

Let's look at some of these tricks with the so-called HDR or High Dynamic Range to get
High Dynamic Range or HDR is a technique that combines multiple images at once to enlarge the picture "dynamic range". Dynamic range is the amount of exposure between the bright and dark areas of an image with low dynamic range images so bright dark shadows, while the lights balanced with High Dynamic Range lighting with more information. The most popular use for the current software, standardization of HDR lighting, while significantly increasing the level of detail, especially considering the images of urban landscapes at dusk or at night, to give the impression of hyper-real, or even real. Redundant with HDR can look cheap, but some professional photographers the technology, if misused, will attract attention.

In fact, the greatest need for software support this technique. HDR imaging techniques, mainly based on the software, and while it is possible for high dynamic range display using Adobe Photoshop to create $ 700, it is an easy way to do it with a cheaper plan. Two pieces of HDR software Photomatix Pro as it HDRsoft ($ 99) and Unified Color HDR PhotoStudio ($ 149), which does basically the same but a little different. An HDR image with one of the programs you need to create three or more images of the same scene to begin, each with different exposure settings. The best way to do this is to mount digital SLR camera on a tripod and auto-exposure, using the camera assigned (AEB) mode, which automatically and quickly for a few photos with low light settings, medium and high. Then you load the image processing software, HDR combines them in one shot. How dramatic or subtle, you want the HDR effect is up to you. Tone-mapping setup you can change the saturation, lighting and other visual elements in the picture.
Again .. With this technique would be to make the results of the image as much as possible.
