CMOS x CCD sensors.

Dear members:

I am interested in your opinions on the differences between CCD and CMOS
sensors for SLR digital cameras. Which one is the best ? Which provides the
best image quality, color fidelity and reproduction, greater color space or
color gamut, ... ?

Suggestions and input on both Sigma's Foveon sensor as well as that
available on Fuji's line of digital SLRs will also be relevant and
appreciated.

I am also interested in reading reviews published in either print
journals/photo magazines or online publications. Are there any reviews you
would recommend ?

Thank you in advance and best regards to all.

Is light sensitivity also a factor? Color space gets into another issue, as
does speed. If quality is paramount, one of the large format camera mfrs
just released a 22Mpixel camera.. As with a film camera, the variation in
intensity within a picture may exceed the sensors range. For example, you
may need to take three pictures, each with a different "exposure value",
then combine them with a photo editor to obtain maximum detail.
Finally, is a camera's "raw format" mode usable with other than the mfrs
software? Otherwise the cameras output will be confined to "standard"
colorspaces, such as sRGB or perhaps Adobe's.
In otherwords, a camera is the sum of its parts.
I'm not even going to get into printer color space and limitations.

CCD stands for Charge coupled device. CMOS stands for Capacitive Metal
Oxide Device

CMOS is the type of device to make a CCD

I hope this answers the question.

CMOS usually stands for Complimentary Metal Oxide Semiconductor.

This means two MOS transistors in a class B configuration (push pull). Is
this not the case with optical devices?

No - CCD is not made out of CMOS devices, if that is what you are saying.

CCD and CMOS detectors are based on different technology. CMOS - which
dedicates more of its area to electronics - was thought to be inherrently
too noisy to compete with CCD detectors, but that has changed.

Thank you very much to all who responded my post. Your answers have been
very helpful. Is there a book any of you might recommend that would cover
this issue in detail ?

Best regards,
