I've been using (well, little more than experimenting) with CS2's* HDR function with varied and limited success.
What I'm looking for either a stand alone program or PS CS2 compatible plug-in that has a more intuitive interface than the CS2 HDR automation and is able to handle the importing of raw (or converted TIFF/PSD etc) files, combining and tone mapping the files in to a final HDR image.
Obviously needs to be OSX (10.4 /10.5) Mac compatible (using dual processor G5 tower so windows/linux under bootcamp or parallels is not an option until work replaces it with an intel mac at the end of this year)
*yeh yeh CS2, old school, I know, but that's what work supplies and as my job entails enforcing software licensing with my staff at work I have to maintain a "keep it legal" machine myself.
