Well, it's also a very simplified one, too. :-) Obviously, a lot of other things could be, and probably are, going on, too. For example, I'd expect that the heuristics in a typical digital camera probably include evaluating some or all of the following: 1) basic image attributes like ISO, aperture, shutter speed, focal length, focus distance, shake reduction settings, camera orientation, flash settings and output power, ... 2) the metering mode, the "film advance" mode, the exposure/program mode 3) the "scene type detection" that drives the matrix metering, including stuff like "smile detection" and "face detection" 4) the image histogram and/or other "transformations" of the image data, like looking for contrast or color gradients, depending on the amount of processing horsepower in their new support chips ... maybe by looking only at the small JPG thumbnail image rather than the full RAW stream 5) data available only inside the camera, like stuff reported by the exposure or sensor circuitry that never gets "off the chip", so to speak And probably other stuff I haven't imagined :-) -- Thanks, DougF (KG4LMZ) -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
