  Measurement results of photoproduced excited hyperon states using the CLAS
detector at Jefferson Lab are shown. The invariant mass distribution of the
Lambda(1405) has recently been shown to be different for each of the three
Sigma pi channels that it decays to, showing that there is prominent
interference between the isospin I=0 and I=1 isospin amplitudes. Measurements
of the differential and total cross sections of the three hyperons
Lambda(1405), Sigma0(1385), and Lambda(1520) are presented and compared.
Prospects of future studies using a 12 GeV beam with the GlueX detector are
briefly given.
