Strömgren and Hβphotometry of O and B type stars, generally brighter than 9.5 mag is reported for the field of the Carina Spiral Feature. The observations are based on the PPM catalogue identifications and are designed to improve the completeness of the existing $uvby\beta$data for the bright early-type stars in the field. We present new uvbyphotometry for 283 stars and Hβphotometry for 225 of them. These observations are part of an ongoing effort to study the structure of selected star-forming regions in the Milky Way by means of $uvby\beta$photometry. A comparison of the new data to other $uvby\beta$data sets for this field is presented.
