Raw vs JPEG experiment

[harrynkl]

It is widely believed that digital cameras' raw image modes offer a significant advantage in overall image quality compared to JPEG modes, at least for photos requiring significant amounts of postprocessing. Brad Templeton posted as a challenge a request for a single image where such advantages are visible; if no advantage could be found even on heavily manipulated images, use of raw mode would consititute an unnecessary waste of camera memory and postprocessing time. This experiment is intended to answer his challenge.
