Photometric calibration is the top systematic uncertainty in measurements of Type Ia Supernova distances used to infer cosmological parameters. Uncertainties in the calibration can come from a variety of sources, e.g., measurements of the system throughput, the slope of the photometric response with wavelength as determined from spectral standards, and the relative consistency across the focal plane. The combination of these systematic uncertainties when propagated to a constraint on the nature of dark energy are roughly equal to the statistical constraints from over 1000 SN Ia. In what follows, we give a brief overview of the various types of calibration uncertainties and recent progress to reduce them.
