I forgot to mention that the D3100 will allow you to shoot both Raw and Jpeg Fine Large simultaneously. In other words the camera will create two seporate files: a NEF file and a Jpeg file. This will allow you to practice converting the Raw files and still have the Jpeg to fall back on. Keep in mind that Raw Files are larger and require more Hard Drive space to store. That is the only downside. That said, Hard Drives are reasonably cheap so it is not much of an issue. Good Luck and Enjoy your Nikons!
