While perusing Adobe TV tonight, I ran across this nice tutorial on using the Merge to HDR Pro feature in Photoshop CS5. In the 10-minute video, Julieanne Kost provides a pretty basic overview of HDR and then digs into the meat of the Merge to HDR Pro feature. In the last couple of minutes of the video, she shows off the power of HDR Toning if you just have a single image to work with. If you’ve been thinking about trying HDR with CS5, this should get you up to speed rather quickly.
If the embedded video above isn’t working for some reason, you can also find the video over at Adobe TV.
