Here's an example. I was taking a shot of a small pond with the sun in the frame. When the sun is in the picture, it is very common for the highlight detail to get completely lost. It is much easier to recover shadow detail, so I shot the image underexposed using the exposure compensation setting. This helped to keep the sky more or less in the correct exposure. The image looked like:
After a few tweaks in Lightrom (or any RAW image converter, including the one that comes with the camera), the image looked like:
Yes I know it's upside down. That's on purpose, probably because I'm crazy. This does show you the kind of shadow recovery that's pretty easy to get with the K-30!
