The composite color frames that make up this “right-eye” image consist of seven frames, taken with different color filters that were enlarged by 500 percent and then co-added using Adobe Photoshop to produce, in effect, a super-resolution panchromatic frame that is sharper than an individual frame would be. This panchromatic frame was then colorized with the red, green, and blue filtered images from the same sequence. The color balance was adjusted to approximate the true color of Mars.
