film image exampleNear a city, like Baton Rouge, a picture of a galaxy taken with a conventional film camera (left) will very quickly be fogged by light pollution. A digital CCD image of the same galaxy (right) can be processed to minimize the effects of city lights.



Digital image exampleDigital image manipulation exampleA same digital image can be processed to show the faint details of galaxy arms (left) or bright features, such as a supernova, near the galaxy core (right).
