At 04:16:30 UTC Mastcam Left took this nice photo of the inner rim of Gale Crater.
The horizon appears veiled by a kind of haze very similar to that observed here on Earth during humid days, but less intense than in other photos.
If this haze was due to dust in suspension it would appear ocher in color and not tending to blue as in this case.
Also in this photo the variations in the color of the terrain create a sort of rainbow as you go toward the horizon, with the far peaks decidedly bluish.
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.
