Adobe Photoshop CS2 Workflow
HDR generation and processing is built into Adobe Photoshop CS2 and Adobe Bridge, so if you already own PSCS2, you don't necessarily need to purchase a new software title for HDR processing. Adobe Photoshop CS2 is very expensive (at minimum several hundred dollars for a license), and these functions only ship with the full version; they're not included in any version of Adobe Photoshop Elements. Nonetheless, a limited-time trial version of the program may be downloaded at www.adobe.com for both Macintosh and Windows operating systems.
Adobe Photoshop CS2 doesn't allow "pseudo-HDR" processing of a single image, or of a post-processed psuedo-bracketed series from a single image. The source image series for HDR generation with Adobe Photoshop CS2 should have a good degree of difference in exposure values between the images. You want at least three full stops between the underexposed and overexposed image, to be safe.
You're going to work on three images from a five shot Auto Exposure Bracketing sequence in this tutorial.
HDR Generation with Adobe Photoshop CS2
Launch Adobe Bridge and Adobe Photoshop CS2. Open the logically-named LDR source image series folder into Adobe Bridge. For selecting source files, you want to use details view, activated under View>As Details because it offers exposure information alongside the thumbnail.
Highlight the source images to be merged to a 32-bit HDR. Images may be JPEG, TIFF, PSD, or Camera RAW format.
