Ok,
This is a dumb question I'm sure but here goes anyways....
I think that color cameras usually result in less resolution than mono with filters because of the bayer matrix process of using several pixels to create a color output.

Ergo, if I switch my Canon 20Da to black and White and used RGB filters (if that's even possible)....

would I get sharper final results with greater resolution?
3 to 4 times better?

Gimme a minute to go hide behind the couch and let fly!

Seriously though, thanks in advance for responding, admittedly after a good belly laugh

The answer is simple: No.

When you set the camera to B&W you don't change any of the collected info. The photons still go through the Bayer matrix and you still collect exactly the same number of them. The only thing that changes is how your camera processes the raw images. The other point you raise is about resolution. There is a common perception that the resolution of a OSC camera and a monochrome camera differ by a factor of 3-4. This is wrong. The interpolation algorithms are pretty sophisticated and the difference is actually around 1.something.

Frank - its still the same colour chip taking the pics - then it is converted to B&W by the camera...same resolution unfortunately

Never be embarrassed to ask questions even if you think they are dumb I even thought the same way you did (wishful thinking)
