But as discussed... sometimes the a(whatever) filter can have a deliterious effect on the image, so I don't want the camera dictating what my image looks like.
If you are talking about the AA (anti-aliasing) filter, then shooting in RAW won't remove its effect. The AA filter affects the light BEFORE the signal is acquired by the sensor, so the image format is irrelevant.
Now, shooting in RAW has the distinct advantage of flexibility in PP, is a lot more forgiving to user errors, and has the enormous advantage of using a quad core i7 instead of a tiny Digic 5+ to do the image processing (in my case).
Unless you are really trying to save space I don't understand why you should shoot in JPEG, because even if you shoot in RAW batch processing to JPEG only takes a couple of minutes. Also, with the 5DIII I can shoot both (my wife gets impatient about posting pictures as soon as they are shot- long story).
So Dylan, why DO you shoot in JPEG? I'm curious.
