Proper calibration of photometric redshifts with LSST is of the utmost importance, as many LSST cosmological measurements depend critically on a well understood photometric redshift distribution. We examine the dependence of the photometric redshift distribution versus the specific filter set used, including the addition of near-infrared filters. We also explore measuring the true redshift distribution of photometric redshift bins by cross-correlating the galaxies with a bright subsample with known spectroscopic redshifts. With currently planned spectroscopic samples this method can reach LSST calibration goals.
