Strömgren and Hβ photometry 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 
data for the bright
early-type stars in the field. We present new uvby photometry for
283 stars and Hβ photometry 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
photometry. A comparison of the new data to other
data sets for this field is presented.
