RE: [Digital BW] Shooting Digitally, for Austin

Hi Tim,

I haven't really thought about that.  Obviously, you'd have to do color
space conversion.  I remember a web article that outlined using CMYK, but it
really doesn't give any detailed explanation:

http://www.digitalcameras.com/howTheyWork2.asp

I wish I knew more...and it is an interesting question.  I have a friend who
is designing some consumer level digicams, and I'm sure he has people who
work with him who could possibly answer that question, so I'll ask him.

If you find out anything, I'd like to know!  What I would do, is make a
filter/lense that is a quad prism that takes ALL the info for that 2x2 area
and gives it to each sensor...that way there is NO interpolating, and you
have TRUE color information...but then you get 1/4th the number of "pixels"
(I use that term loosely here ;-) that the cameras that use interpolation,
give you.

Regards,

Austin
