You are still stuck with the RGB values provided by the CCD. They may or may not be sufficient to duplicate what you want (usually not). > But of course you can just use ortho film too. Not if the camera contains a CCD. I've already been down this road with computers for the past few decades. It's the revenue-generating "upgrade every six months" cycle. Great for vendors, and an expensive nightmare for customers. One reason I bought Leica equipment was so that I would _not_ find myself "upgrading" every few months (as I would be compelled to do with certain other product lines, such as Canon). Since I prefer to spend my time actually taking pictures, constant upgrades would be an expensive nuisance. Indeed, I don't even upgrade my computer hardware or software anymore, and for exactly the same reason: I'm doing productive stuff with my computer, so I can't afford to drop everything and start from scratch for the purpose of an "upgrade" every few months.
