You forgot the bayer pattern. Each pixel is only one color, so by doing the shift, they get all three colors at each pixel. I wonder whether the four shots might mean that they have a fourth pixel without any color filters that is much more sensitive than the color pixels. Either that, or with their pattern, it takes four shots to get all colors at all pixels (2 green, one red, one blue). > have a camera shift adaptor that goes on the back of my bellows and is > advertised to increase resolution by shifting and stitching and yes it > does up the pixel count but also the image size so it is more like a > macro panorama adaptor but doesn't increase effective resolution.
