[tweetmeme]HDR or High Dynamic Images can store pixel values that span the whole tonal range of the real world, in the range of 100,000:1. HDR Images are encoded in a format that allows the largest range of values stored with 32 bits per color channel.

According to Wikipedia: high dynamic range imaging (HDRI or just HDR) is a set of techniques that allow a greater dynamic range of luminance between the lightest and darkest areas of an image than standard digital imaging techniques or photographic methods. This wider dynamic range allows HDR images to more accurately represent the wide range of intensity levels found in real scenes, ranging from direct sunlight to faint starlight

HDR images enable photographers to record a greater range of tonal detail than a given camera could capture in a single photo. While many imaging experts regard HDR photography as the future of digital photography, the discipline has long been in existence.

The “merge to HDR” feature of Photoshop allows the photographer to combine a series of exposures into a single image, which encompasses the tonal detail of the entire series.

Here is a list of 5 of the best HDR tutorials in Photoshop. The 2 last tutorials “fakes” HDR with only one image.
