My article on Creating HDR photos with Luminance is up on Windows.AppStorm. A preview:
HDR attempts to compensate for the lesser dynamic range of a camera by taking multiple images that together cover the entire dynamic range of the scene and combining them together to produce a photo that better presents the full dynamic range in the original scene. Many high end graphic processing packages such as Photoshop contain the ability to create HDR images. Other specialty programs designed only to create these images also exist. Creating these images does not require expensive specialized software. Here we’ll look at using the free open source Luminance to produce HDR images.
