My belief is always capture in RAW. 16 bit images have 2**16 range (0=Black to 65536=White). In order to display the image (printer or monitor) it has to be converted to jpeg = 8 bit = 2**8 = 256 levels. You permanently lose a huge amount of data when converting to jpeg so always keep your RAW originals. Eventually your post-processing experience grows and a revisit to some old pics may find you can glean an APOD or two.
