RE: tried some tone-mapping with my car
Looks good - did you use a digital camera with exposure bracketing to take the pictures, or just one source picture?
For those who are wondering - here's the skinny on HDR: http://en.wikipedia.org/wiki/High_dynamic_range_imaging
Essentially it involves taking the same picture with three different exposures - one underexposed, one overexposed, and one with optimal exposure. The source files are then combined, which is what gives HDR its effect.
[blockquote]In computer graphics and photography, high dynamic range imaging (HDRI) is a set of techniques that allows a greater dynamic range of exposures (the range of values between light and dark areas) than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows.HDRI was originally developed for use with purely computer-generated images. Later, methods were developed to produce a high dynamic range image from a set of photographs taken with a range of exposures. With the rising popularity of digital cameras and easy-to-use desktop software, the term "HDR" is now popularly used[1] to refer to the process of tone mapping together with bracketed exposures of normal digital images, giving the end result a high, often exaggerated dynamic range. This composite technique is different from, and generally of lower quality than, the production of an image from a single exposure of a sensor that has a native high dynamic range. Tone mapping is also used to display HDR images on devices with a low native dynamic range, such as a computer screen.

hey pirate, yeah i used a digital camera and took three differant pictures, for maximum detail. if you look closeley the guy in the background is disseapearing into his house becuase of the merging of the diff pictures
