Ok, this lady has a cool job:

SCIENTIFIC pictures are not decoration but knowledge. Felice Frankel, an M.I.T. research scientist (and organizer of the Image and Meaning conference), has had to add a color to certain photographs when the photographic instrument did not pick up a tint she could see with her own eyes; the manipulated image was more faithful to visual observation than the unmanipulated. Illustrations may be purposely simplified to make them easier to understand, especially for the lay public. Some published X-ray images of the stars have been adaptively ”smoothed,” a technique that replaces the value of the intensity of each pixel with the average value of its neighbors, making details easier to see.
