Not exactly. The Foveon doesn’t need the Bayer convolution to get the different color sensing sites to show the same area, because they’re beside each other. With the Foveon, each site is on top of the other, so that isn’t required. The Bayer convolution loses placement data from the individual sites as they are mixed together. The resolution in green is about one third higher than in the Foveon because Bayer sensors use two green sites, as we are more sensitive to green. But as a result it has about 40% more red and blu, resulting in an equal amount of detail across the colors, giving about a 30% higher overall sharpness.No, a 20mp Foveon sensor has the resolution of a 20mp Bayer array sensor with no AA filter, which looks like a 30mp Bayer array with an AA filter (depending on the strength of that AA filter) I never was overdoing it.
most of the tiny amount of detail lose from the AA filter can be recovered by the initial sharpness adjustment made by the software.
the filter isn’t anywhere responsible for the difference, because, at most, for a medium to high rez sensor, no more than about 5% of detail is lost.
you misunderstand what’s going on here. We’re not talking about countable pixels. That remains the same. It’s the sharpness of the individual pixel that’s affected.
