Michael Benson est un artiste qui crée ses œuvres à partir d'images provenant de la NASA, qu'il rassemble, colore et améliore. Le résultat est impressionnant :

What is your process for making the images?
The very large print I have up of Jupiter’s moon Io, right at the limb of the planet, was taken with six camera pointings of the Cassini spacecraft in 2001. Six camera pointings covered the whole planet. The narrow-field camera was pointed at the northeast quadrant of Jupiter, it was a black-and-white camera using the red, green, blue, and infrared filter.
At the end of that process the entire planet had been imaged. It took about 45 or 50 minutes. I went in there and found the red, green, and blue filters. Each had to have an image produced in color. A Jovian day is short, only 10 hours. Jupiter is spinning, the spacecraft is going at the speed of a rifle—a lot of finessing is required.
Finally you get a bunch of mosaic pictures that have to be assembled into a final composite image. That picture took weeks.
What do the original single images look like?
Like a black-and-white, low contrast, relatively low-res thing. You have to do things to “up res” them. I have a software plug-in that is very successful at increasing the resolution.
