Karl I'll care :o) Seriously though: which will the "great unwashed" be more likely to remember. 1) some thorough accurate intercomparisons utilising scientific method 2) an ad-man's one linee "our Spinic II processor working with the ConSeal algorithm produces perfect color (sic) balance every time". Remeber too: that the whole reason (justification) for encrypting raw data is to protect you from yourself. Only the manufacturers can ever understand thier sensors best. Their native spectral sensitivities are irrelavent as long as there is "accurate" post capture (pre-raw) adjustment of the signal. Heck, give the users too much knowlege and they would have to stop calling them digital sensors :o) Bob ___________________________________________________________ Book yourself something to look forward to in 2005.
