At 18:15:42 UTC the Mastcam Left again imaged the inner rim of the Gale crater as in the previous photo from about a month and a half ago (see https://www.facebook.com/PianetaMarte.MdM/photos/a.1625578140858706/2801827566567085/).
Comparison with the previous image shows likely dust clouds, or perhaps dust devils, visible as reddish “wads” in areas previously green in color. There are also noticeable changes in hue in the green areas, with noticeable yellowing.
Definitely interesting to be able to observe all these changes!
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.
