If you are using LR, I highly recommend shooting in J+R mode, which shoots both a JPG for immediate use, and a DNG raw file to use in LR. The DNG file has far more information and dynamic range than the JPG---Optimize the DNG in LR and then export out as a JPG for the best quality. You can recover almost anything out of the DNG, no matter how bad the lighting! The JPG is already precooked in the camera with the unused the ingredients thrown away, while the DNG has all the ingredients the camera started with, and lets you pick which ingredients you want to cook with!
