At 03:35:27 UTC the Mastcam Right captured a rock with an unusual appearance.
It is certainly a sedimentary rock, but furrowed by a myriad of limestone veins, sometimes branched, that seem to converge towards the right side of the rock itself.
Note also the amount of detail present; truly spectacular!
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 a reduction of noise 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.
