On Sol 3, Curiosity took this picture 0003ML0000047000E1_DXXX.jpg. Note the circled area
The same area - from a different angle on Sol 17 (0017MR0051007000C0_DXXX.jpg)
The pipes are there on Sol 17 and 19 but do not appear on Sol 3 - in fact there are a lot of images of the same area on Sol 17 and Sol 19?
I know the photos were taken from different angles, but even taking into consideration some pixelation, it still does not look right
At a guess there is about a 45 degree difference in the direction the photo was taken between the colour photo and the B/W
Examining the colour photo - the black and white photo was taken from the bottom left looking toward the dimpled stone in the background, the only possible "stones" in the area are the ones circled. The left hand "stone" is lower than the right hand "stone" with no visible dark area at the top. The right hand "stone" is curved with a possible dark area, which may be one of the pipes when viewd from a different angle.
Examining the B/W photo, there could be 2 or 3 pipes and they look like they are touching each other. The left hand "pipe" is slightly back from the right hand pipe, which is different from the colour photo, as the left hand stone appears further forward. Also the left hand stone appear to be higher, again at odds with the colour photo
I've not used any enhancemenrts as this sometimes introduces more "noise"
It could be an optical illusiion, or some kind of crystal structure.
