I'm curious as to anyone's thoughts on this. I am sure we all realize the immediate advantage of shooting everything in color, then post processing into B&W but why have Monochrome as a built in option on the EOS camera's? Is there an advantage choosing Monochrome on the EOS Bodies over post processing the color RAW into B&W?
It's a great question. I think the guy at Canon who decided to include the "shoot in monochrome" feature also thought it was a good idea to print directly from the camera.
Definitely shoot in RAW, then processing your photo in monochrome later. That allows you to push and pull the different color channels to achieve the balance that you want. If you just shoot in monochrome, you'll be stuck with whatever you get.
