those curious about HDR images.... HDR photo software & plugin - Tone Mapping, Exposure Fusion & HDR Imaging for photography
basically your eyeball can see approximately 7 stops of light. What an HDR image does is attempts to recreate what your eye sees lighting wise versus what a camera can only pick up by exposing both the highlights and shdows properly through the use of multiple images. HDRs is particularly useful in images where if you expose for something and the background or foreground winds up over exposed (see link above). You don't need 3 images, you can do it with 2, or with my Nikon D300 I can set my function command dial so that I can take as many as 9 images at 1.0, 0.7, or 0.3 stops. You can also cheat in taking that many images, but only if you fire your shots in RAW (NEF for me) file format. With a RAW (NEF) image I can load it in one of the newer Photoshop programs, CS3 comes with CameraRaw which supports the D300 RAW format, or I can use the camera manufacturer's editing software (ViewNX for Nikon). From there I can take the image and adjust the exposure compensation within the program. You can even use photoshop, I think it started in CS2, for creating HDR images.
Personally, I prefer to use essential hdr over photomatix and photoshop for hdr image creating. Those interested in more images I highly suggest searching pbase.com for hdr images. Some of them are freak'n remarkable.
PwrRngr...you might want to play with the tone mapping some more. Though a personal preference, many within the photographic communities try to not make the images look so baked and thus fake-ish looking.
