Re: Foven questions

[Arthur Entlich <artistic-1@xxxxxxx>]

We still don't even know if they are appropriate for digital camera 
technology... ;-)

The main advantage of their use in digital cameras is that each data 
point captures all three color components (RGB), rather than the current 
system which uses a Bayer pattern and interpolation, capturing only one 
color per data point.

Current linear CCD film scanners capture all three colors per data point 
by using three offset lines of CCD sensors, so there is no advantage in 
that aspect.  If the Foveon can be found to be as noiseless or more so 
than current CCDs used, or can improve resolution, and can speed up the 
whole process by capturing the whole image or a larger part of it at 
once, then potentially it could be an improvement.

I'm sure it is/or has been looked at.  The question is will it improve 
the results, and will it be cost effective?  The current crop of Foveon 
chips being produced for the Sigma SLR do not have the resolution that 
current 4000 dpi filmscanners can produce.
