  We report the exclusive photoproduction cross sections for the Sigma(1385),
Lambda(1405), and Lambda(1520) in the reactions gamma + p -> K+ + Y* using the
CLAS detector for energies from near the respective production thresholds up to
a center-of-mass energy W of 2.85 GeV. The differential cross sections are
integrated to give the total exclusive cross sections for each hyperon.
Comparisons are made to current theoretical models based on the effective
Lagrangian approach and fitted to previous data. The accuracy of these models
is seen to vary widely. The cross sections for the Lambda(1405) region are
strikingly different for the Sigma+pi-, Sigma0 pi0, and Sigma- pi+ decay
channels, indicating the effect of isospin interference, especially at W values
close to the threshold.
