  I review hard photon initiated processes on nuclei. The space-time
development of the DIS reaction as viewed in the target rest frame
qualitatively describes the nuclear shadowing of quark and gluon distributions,
although it may be difficult to understand the very weak $Q^2$ dependence of
the low $x$ data. The current jet hadron energy distribution at large $\nu$ is
accurately independent of the target size even at very small energy fractions
$z \simeq 0.05$. Color transparency is verified for vector meson $(J/\psi,\
\rho)$ production, but remains enigmatic in quasiexclusive proton knockout
processes. I emphasize the importance of understanding short-range correlations
in nuclei, as manifested by subthreshold production and cumulative $x>1$ DIS
processes.
