Oh... and the classic way to do the sky thing would be to buy a graduated neutral density filter to screw onto the front end of the lens. That way you can filter out some of the light from the sky while getting all the light from the ground. However, they're a bit expensive and do not always give great results if you shoot anything besides landscapes... so I would still recommend RAW files and Photoshop. If you do not want to mess with image software, check if your D60 has a setting for "Active D-Lighting" and set that to "high", that makes the camera even out the dynamic range of the exposure a bit. Might help.
