Re: stupid digital camera and filter questions

But that one red channel is adjustable, so its infinitely variable. 
What's more, one can adjust the tonality of the color original in other 
ways -- shadow/highlight, curves, selective color, color replacement 
etc. -- so almost any grayscale variation is possible.

Simulating the filters in Photoshop is easier than carrying a bunch of 
filters around, but you can only accurately simulate a limited range 
of filter effects.  For example, you can buy a number of red filters 
that do different things to your photo, but there's only one red 
channel...
