Also, I've now actually read the message everyone is talking about - I'm afraid I got things a bit mixed up earlier - and it all became a bit clearer. I don't agree that this is "because of the way digital sensors work", though. I'd say it's because of the way you convert the data or because the way humans perceive colour, but I guess it depends on where you come from. To me, the fact that digital sensors are linear devices and/or "photon counters" is the obvious part. What's a lot less intuitive (although I really should know about it), is that the human eye or perception is not, and that you want to adjust your final output based on that. - Toralf -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
