That said, I shoot RAW almost
exclusively, but there are times when JPEG makes more sense. And if
I generated a higher volume of work, I'd surely develop a method of
shooting accurate JPEGs in camera (along with RAW files, I think).
Again, I'm the opposite. JPEG is good for low volume work, but if
you're shooting, say, a portait shoot consisting of strings of
hundreds of images under similar lighting and exposure conditions,
RAW works better. Just custom tweak the first image in that series
to your liking, then apply that "recipe" or "formula" to all the
other images in that series. And that's true even for situations
where you thought you had everything perfect, or near perfect, at
the time of shooting. RAW lends itself very well to very minor
tweaks of large quantities of photos (I like to call them
"optimizations" of almost ideal exposures). It's not just good for
major tweaks of photos.
