  Two-dimensional surface photometry is presented for a sample of 351 late-type
galaxies with $0.12 < z < 0.65$. These objects are drawn from the Canadian
Network for Observational Cosmology (CNOC) cluster survey and are either
spectroscopically confirmed members of clusters at $z=0.23$ (64 galaxies),
$0.43$ (45), and $0.55$ (36) or field galaxies with similar redshifts. Galaxies
in the rich cluster Abell 2256 at $z=0.06$ were also analyzed with the same
methods to provide a local reference point. At redshifts of (0.23, 0.43, 0.55)
the disk surface brightness in cluster late-type galaxies is higher in the
$B$-band by $\Delta \mu_{0}(B) =(-0.58\pm 0.12,-1.22\pm 0.17,-0.97\pm 0.2$)
mag, respectively, relative to the Freeman (1970) constant surface-brightness
relation; whereas disks in cluster galaxies at $z=0.06$ are consistent with
that relation. Field galaxies show a progressive disk-brightening with redshift
that is consistent with that seen in the cluster population. Taken together
with similar measurements of early-type galaxies (Schade et al. 1996a), these
results suggest that the evolution of the field and cluster galaxy populations
are similar, although we emphasize that our sample of cluster galaxies is
dominated by objects at large distances (up to 3 Mpc) from the dense cluster
core, so that the implications of these findings with respect to the
Butcher-Oemler effect and the morphology-density relation will not be clear
until an analysis of galaxy properties as a function of cluster-centric
distance is completed.
