This pair of images, obtained by Phobos-2 in 1989, make a good example of what Phobos-2 images look like. The aspect ratio has to be fixed, and extensive noise removal, calibration, and cleanup is needed. Also, due to the significant time lag between images, Phobos and Mars have to be processed separately, because they have shifted relative to one another. Color has to be filled in for areas of Mars obscured in one image but not the other.
