So your idea is to use the CIS bars, in a 3 set to obtain
a RGB image,....wouldn't that be a rather large piece
of hardware to carry?


No, CIS would work for monochrome capture
only, I don't see any easy way to adapt it
for RGB capture in a camera.

Given the quality of LF B&W films and silver prints
I don't see that being of much interest or use, to me.

Please define "aerial image."

Rafe, I am refering to capturing an image using a very small lens at the
plane of focus. It seems appropriate with scanning technology which makes
discrete steps across the plane.

I am saying that
either a CCD or CIS sensor could be waved across
the film plane and capture the image that was
on the ground glass.

I think we are talking about the same thing.

Not really. A lot of LF photographers don't shoot color film.

Not only that, but the ones that do, shoot a lot more than others. You
also have students that use LF cameras supplied from schools, are having
film processed.


IIRC all jobo processors support 4x5, and the ATL series automatic ones
have prices that are comparable to many new LF cameras, esp from Linhof.
It also gives you fast medium format and 35mm chromes.

Of course a new toyo + processor + a couple of lens + loader + a mountain
of film + chemicals costs less than a 1ds mark2 body alone, but thats
off-topic.

I can recommend Jobo processors to anybody I have been very happy
with mine.

Why do you have to drag digital imaging into every photography group ?
