Photoshop CS2 introduced the application’s first support for 32-bit high dynamic range (HDR) imaging.  The support was pretty limited, consisting of the Merge to HDR command (for combining bracketed shots into a single image) and some basic imaging functions (cropping, cloning, conversing from 32 to 8 or 16 bits per channel).  Even so, about a year ago examples started popping up<\/a> of HDR experiments (not solely connected to Photoshop, of course, but helped along by CS2).  In the time since then more good resources<\/a> on the subject have emerged. <\/p>\n

The Photoshop CS3 beta includes some improvements in the HDR realm.  Some more functions (e.g. Levels) are enabled for 32-bit images, and the Merge to HDR command, although superficially similar to the one in CS2, contains a variety of improvements.  It benefits from the new image alignment<\/a> code; preserves a more complete set of source data; and uses improved algorithms for merging the data. <\/p>\n

Trevor Morris<\/a> has kindly supplied an HDR photo<\/a> created with the CS3 beta, as well as the source frames<\/a>.  He says, "I could never get it to work in CS2, but it worked flawlessly in CS3, and I was quite pleased with the results."  He writes, <\/p>\n

This photo was shot inside the Christ Church Cathedral, located in Fredericton, New Brunswick, Canada.
\nFor this particular shot, I used a tripod and remote to capture 12 exposures, from 1\/125s to 20s, with a Nikon D70 @ f\/16, ISO 200, FL 18mm. I combined the exposures using Merge to HDR, increased the local contrast, and gave the image a slight saturation boost. <\/p>\n<\/blockquote>\n

Give it a whirl with your bracketed shots, and please let us know whether it works well for you. <\/p>\n","protected":false},"excerpt":{"rendered":"
