As soon as I got my Canon Rebel xTI, I started to almost exclusively shoot in RAW. For essentially two reasons. One, I don’t have to worry about white balance. Two, I have complete control (OK, almost complete control) over the data.
That is important to me because even though I try as much as I can to prepare a photograph, set up light sources, blah blah blah – the way I shoot is almost always dictated by what happens at that moment. My best shots are born out of spontaneity.
This spontaneity, though, means that I may have an ISO setting on the camera that is not fast enough, a shutter speed that doesn’t work etc. RAW has helped me more than once salvage a photograph which, had it been taken in JPEG, would not have been salvageable, or only after LOTS of work. If the white balance is off, I can easily correct it. If it is underexposed, I play with a few sliders.
Inevitably, a lot of times salvaging a photograph introduces noise. I have come to appreciate that, however, because it can look quite interesting as a black-and-white. Therefore, I typically convert to black-and-white in such a case, and the results have been astonishing. Alternatively, I may take a picture in a very high ISO, then convert it to black-and-white at least partially. The photograph of the wine glass was taken at ISO 1600 with no flash present, then partially left a color photography, while the rest of it was converted to black-and-white.
A good book on RAW conversion, at least to start with, is “The Art of RAW Conversion” by Uwe Steinmueller and Juergen Gulbins. Even if you buy it only for the stunning cover photograph. It gives a very nice intro into what RAW conversion is, what potentials it holds and when to use it/not to use it (for the latter, any type of photograph that requires fast camera action, such as sports photography, probably does NOT lend itself to RAW). Check it out!
