At 19:04:32 UTC the Mastcam Right photographed this group of stratified rocks, some with a smooth surface and others particularly “rough”.
The rock just below the center of the photo even seems to defy gravity, while it is probably simply a single body with the part below on which it seems only leaning. I think the impression that these are two separate rocks is due to their obvious morphological diversity.
Also note the darker sand around the larger rocks and the ever-present colored spots.
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.
