high dynamic range (HDR) image compendium

This is a collection of HDR (High Dynamic Range) images that are pulled from my other galleries.

They all involve exposure bracketing, combining the images into one 32-bit (floating point) HDR image,
and then tone mapping the HDR image into 16 (or 8, for display here) bit dynamic range.
This preserves the detail in bright and dark areas, all of which is used in generating the final image.

The camera was set to auto-exposure-bracket a sequence of three images ("correct" exposure, underexposed, and overexposed).

Photomatix Pro used to create the HDR and tone-mapped images, but this capability now is included in Photoshop CS2 (haven't upgraded yet).

For the panoramas, the HDR "slices" were generated before stitching, although others may advocate the opposite order of doing this.
With 3-image HDRs, that triples the number of images need to generate the panoramas. Whatever the workflow, I think the result is worth it (you be the judge).
Best viewing of large images in "original" size.
