The Carnegie-Irvine Nearby Galaxy Survey (CINGS) is a project designed to study the detailed structural properties, mass profiles, star formation histories, and AGN content of nearby galaxies across the entire Hubble Sequence. The sample includes the 603 brightest southern hemisphere galaxies with B_T < 12.9 mag. The survey consists of imaging in the BVRIK_s wavebands, obtained at the du Pont 2.5-meter Telescope at Las Campanas Observatory. Median seeing is 0.6 arcsec and the images reach depths of 29, 28.5, 28, 27, and 23 magnitudes per square arcsecond (3-sigma). In the future, we will also obtain multi-slit spectroscopy to study kinematics, stellar populations, chemical abundances, and active nuclei. Currently, all optical images have been obtained and reduced, and data collection in the K_s band is well underway. Our imaging analysis will consist of both 1-D radial profile measurements and detailed 2-D model fitting of galaxy subcomponents, including non-axisymmetric features such as bars and spiral arms. On completion of the survey, the images and data products will be available as a public archive. Here, we present initial results from the imaging survey, including surface brightness profiles in the BVRIK_s bands, 1-D bulge-disk decompositions, and color profiles.
