  The OSIRIS camera onboard Rosetta successfully acquired images of asteroid
2867 Steins through a variety of color filters during the flyby on 5 September
2008. The best images of this 5 km diameter asteroid have a resolution of 78
meters per pixel. We process the images by deconvolving with the point spread
function and enlarging through the Mitchell-Netravali filter. The enhanced set
is analyzed by means of various techniques (PCA, band ratios, stereo anaglyphs)
to study surface morphology and search for variegation. We identify a
landslide, which supports a YORP origin for Steins' unusual diamond shape. In
addition, we find that the interior of one of two large craters on the south
pole is bluer than the rest of the body.
