The camera and software do not reveal data (detail, tonal info, whatever) that didn't get recorded by the chip. It can take the data that the chip provides and massage it til the cows come home, but no new data will be created, at best only extrapolated data. Whether that data is more pleasing or not is beside the point. If the software is lucky the new data might actually bear some resemblance to reality or to data that might have been captured by a better chip, but more likely it has nothing to do with reality; it is a figment of the software designer's imagination. It's like taking a photograph and, using a paintbrush, painting something more to your liking over it. Maybe more pleasing, but further from the reality that a good chip can capture. In a crude analogy, it's somewhat like brain surgery. We can 'fix' things, and make the result more pleasing, but we can't increase brain function in any real way. > >Clearly the software cannot reveal data which does not >exist > > >Frank -- * Henning J.
