![]() ![]() Maybe no one has seriously considered this alternative approach yet because photographers wouldn’t have sacrificed their megapixels in the past. ![]() The idea is strikingly simple: If we don’t treat the four monochrome red + green + green + blue pixels of a Bayer sensor as four individual pixels, but mix them down into a single pixel, then that pixel will have true color, not the reconstructed color of conventional debayering and its algorithmic guesswork. Since no algorithmic reconstruction is required for the recorded pixels, both their color reproduction and per-pixel sharpness are unique.īut we can achieve a working equivalent of true color pixel capture for conventional Bayer sensor cameras – if we are willing to sacrifice megapixels in the final image. Foveon and 3-chip cameras, on the other hand, record true colors per pixel because their sensors can see red, blue and green simultaneously. The colors we see in the final 24 megapixel image were algorithmically guessed from this monochrome pixel grid. ![]()
