I'm still trying to learn Photoshop and I've been wanting to try out the High Dynamic Range feature for a while, but hadn't taken time to do it. What it does is merge several images taken in a high contrast setting and blends the best details from each to give a composite photo. A blown out sky in one photo is replaced by a "normal" sky exposure from another image. The key is to take several identical images with different exposures so that the detail is maintained from the shadows to the highlights. To try this out, I took three shots of the skylight in our upstairs hall since I knew this would have lots of contrast. I'm posting two photos. The first (the one with the watermark) is one I just lightly edited in Lightroom. The second photo is one where I blended the 3 images with the HDR merge function in Photoshop. Since I like photos with lots of contrast, I actually like the one from LR better in this instance, but I appreciate the technique shown in the second shot where there isn't as much shadowing in the highlights and the reflection has more detail. (This may be difficult to see unless you enlarge the images). I'll be interested to use the technique again in a situation where contrast is more of a composition challenge. At least this gave me the chanced to figure out how to do it in PS.
