The key to the "digital look" is tied to the interpolation algorithms that are implemented to decode the mosaic (ie non-continuous sensor) array. For an interesting article see: http://ise.stanford.edu/class/psych221/99/tingchen/ There are many photoshop compatible plug-in filters (algorithms) that do a good job of filtering the grain in areas of sky to make them appear like a digital captured image. We are back to the same arguments of PCM vs analogue audio, the dispensation of noise and lower apparent distortion of the reconstructed analogue signal from the PCM stream was touted as the road to audio nirvana. As we now know as far as convenience it's been a huge success but for those really in the pursuit of audio nirvana it seems that analogue still takes precedence regardless of the inherent higher background noise etc. Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://members.ozemail.com.au/~distudio/publications.html
