At 11:47:20 UTC the Mastcam Right shot an area adjacent to, but more to the left of, the layered knoll shown in the previous photo (see https://www.facebook.com/PianetaMarte.MdM/photos/a.1625578140858706/2557308307685680/).
Again we note a nice variety of colors and brightness, as well as streaks of sand darker than the adjacent terrain that seem to spring from the crevices of some rocks.
Simple darker sand or small water flows?
The original image is a black and white encoding of the Bayer mask that has been converted to color through a process called “debayering” or “demosaicing.” In addition, the photo has undergone noise reduction due to Jpeg compression, white balance and a slight increase in microcontrast and color saturation in order to make the colors more similar to what the human eye would see.
