Four-image NAVCAM mosaic of Comet 67P/Churyumov-Gerasimenko, using images taken on 24 September 2014 when Rosetta was 28.5 km from the comet. On the left, the contrast was enhanced by setting the darkest pixels as black and the brightest ones as white ; on the right, the intensities were scaled so that the mean brightness of fully illuminated regions of the comet is around 4%.
