Foveon black and white? Sensor question.
2 months ago

Most of us know that the color conversion of Foveon creates awful lots of noise to color images and that the colors are often problematic or downright errornous, but what about black and white photography?

If Foveon captures significantly more photons per pixel than a converntional sensor with it's color filtered pixel, should Foveon then be far surperior device for black and white photography in low light as well, than Bayer CFA-sensors of similar size, and about as good as the modern full frame sensors?

If the sensor captures maybe 2 times the light (no filters, but more wiring), the large readout noise should be a non-issue for much deeper into the shadows than with the conventional sensors.

The question is: is Foveon that good for low light black & white photography, and if not, why not? Does the triple photodiode pixel structure have some significant non-light sensitive zones?
