Digital Photography - Raw, jPEG, or Both?
If you intend to do any manipulation or retouching, shooting raw is often the best solution thanks to its increased bit depth.
However, raw files are larger, so take longer for the camera to deal with, and you also need to process them before they can be printed.
JPEG files, on the other hand, are processed in-camera at the time of shooting, so you can print or share them immediately, and you'll find that you can shoot a much longer burst of consecutive frames at a much quicker rate.
Providing you don't want to make too many radical changes to an image after you've taken it, you may find you can't tell the difference between a JPEG file and a raw one.
For the ultimate in choice, though, and when speed isn't important, why not shoot both? Most digital cameras give you this option, and you can then decide what you want to do when you're back at your computer. Just make sure you pack an extra memory card.
