The left (Sx) side of this picture (which is an Extra Detail Magnification of an Original White-Balanced Color Image obtained by the NASA - Mars Curiosity Rover and Laboratory on April, 15, 2015, and identified, on the NASA - Planetary Photojournal, by the ID n. PIA-19400) has been additionally processed, magnified in order to help the visibility of the Landscape's details, Gamma corrected and then re-colorized in Absolute Natural Colors (such as the colors that a normal human eye - in the average) would actually perceive if someone were on the Surface of Mars, near the NASA - Mars Curiosity Rover and Laboratory, and then looked ahead, towards the Horizon and Sky above Gale Crater), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.


On the other hand, the right (Dx) side of the picture has also been additionally processed, magnified in order to help the visibility of the Landscape's details, Gamma corrected and then re-colorized, but this time in Natural Colors (such as the colors that a perfect human eye - or an Electronic Eye) would actually perceive if someone were on the Surface of Mars, near the NASA - Mars Curiosity Rover and Laboratory, and then looked ahead, towards the Horizon and Sky above Gale Crater), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
