I think many of recent camera has HDR function including iPhone4. This is one of the 21 century’s best ideas to develop pictures. Here is some explanation from Wikipedia:In image processing, computer graphics, and photography, high dynamic range imaging (HDRI or just HDR) is a set of techniques that allow a greater dynamic range of luminancebetween the lightest and darkest areas of an image than current standard digital imaging techniques or photographic methods. This wide dynamic range allows HDR images to more accurately represent the range of intensity levels found in real scenes, ranging from direct sunlight to faint starlight.

This is example at Monument Valley restaurant.
