How does Curiosity Mars Rover take pictures of itself?
Answer (1 of 14): Just a bit of photoshop cleverness. The final picture is a mosaic created from about 30 or more individual shots taken from many slightly different angles, the final shots used to create the mosaic are all ones where the arm cannot be see...
That's how most of the pictures are, and have been for ages, not just of the rover itself. They're all doctored in Photoshop. Same with orbital telescopes, though there are good technical arguments, there (they're often coloring non-visible spectra). It's easier to make and apply a narrowly focused camera, for high detail, than make cameras with wide views that also can tightly focus. You then take many overlapping pictures from that camera.
For Mars, there is a good argument to be made thar adjusting things like color, and opportunistically removing details, is being done so that we don't see everything they're receiving.
