It's not exactly a secret that those glorious space images NASA and other space agencies release go through extensive 'Photoshopping,' just like magazines and billboard ads. Now, Adobe has explained what exactly happens during the post-processing stage.
The person who does the retouching can't be an ordinary graphic designer: it usually has to be an astronomer. That's because they have to be able to interpret raw data and differentiate image artifacts that need to be erased from vague planets and cloudy nebulae, among other celestial bodies.
