I know that newer/better processors result in less noise when using the same sensor (T3i vs T4i for instance) for JPG shots but what I'm curious to know is - should I get the same results when I take a picture in RAW and process via DPP vs in-camera JPG - WHEN AN EQUAL AMOUNT OF PROCESSING IS APPLIED?
Thanks for any insight!
You probably are not getting many answers because your premise is probably not possible. The in camera processor is different from DPP, and its really not possible to apply the same amount of processing because we don't know exactly what is happening.
The in camera processor is not nearly as powerful as the raw processor in a computer, and the DPP in your computer is likely a newer, better algorithm, and it has a much more powerful computer to drive it, so it can do a finer job.
The best I can say is that if you use the same settings in your camera and in DPP, then the colors will be the same, and contrast and brightness will be very close.
Test it your self, shoot raw + jpeg and compare the shots in DPP.
