I have a warm place in my heart for Photoshop plugins... and at the moment Photomatix Tone Mapping Plug-in 1.0 from
MultimediaPhoto has my attention. Designed for Photoshop CS2, its function is to compress the tonal range of HDR images whilst maintaining proper contrast. To the uninitiated, this means that the image displays properly on normal LCD monitors with minimal calibration. Ideal for those individuals with an interest in Photography and a decent high-megapixel SLR camera. Its pretty cheap too, at $69 or $19 for owners of Photomatix Pro.
