I'm immensely enjoying my D300, which I find much more intuitive than my beloved D70, but there's probably even more to learn about the D300 than there was with the D70. My more immediate question concerns the advantages of shooting in "raw" mode as opposed to JPEG (which I normally do). I understand that raw is the "native" resolution of the sensor (please correct me if I'm mistaken) and that I'll have more opportunity to "retouch" an image (also, something I really don't do) but ultimately I'm creating a JPEG image for printing (I usually send out for this). So. Plainly: Am I "losing" picture quality by shooting in the highest JPEG format?
