Results are presented of CCD Stromgren photometry in the region of the young SMC globular cluster NGC 330. The goal is to derive metallicities for yellow and red supergiants both in the cluster and in the field. First, a previous metallicity calibration based on Stromgren colors is updated, and it is demonstrated that a calibration based on giants is indeed applicable to supergiants. The main result is that the metallicity of the cluster stars is lower by about 0.5 dex than the metallicities of field stars, in agreement with earlier spectroscopic work. Also, the absolute metallicities agree well with the spectroscopic values, which demonstrates the potential of Stromgren CCD photometry in the Magellanic Clouds.
