The Sigma SD-14 will have a 4.69 effective megapixel resolution from 14.1 million photodiodes arranged in three layers, as per Foveon's by-now famous layout which records full color information at every pixel location. (Traditional Bayer-sensor cameras capture only one color at each pixel location, and interpolate the other two colors from surrounding pixels, leading to somewhat reduced luminance resolution, and a significant reduction in chrominance resolution and other color-related problems). Maximum resolution is 2640 x 1760 pixels, with a 3:2 aspect ratio, though the SD14 offers an interpolated "Super High" JPEG mode with 4608 X 3072 pixels. The Sigma SD14 captures either JPEGs or .X3F Raw images.
