  We model effects of color fluctuations (CFs) in the light-cone photon wave
function and for the first time make predictions for the distribution over the
number of wounded nucleons $\nu$ in the inelastic photon-nucleus scattering. We
show that CFs lead to a dramatic enhancement of this distribution at $\nu=1$
and large $\nu > 10$. We also study the implications of different scales and
CFs in the photon wave function on the total transverse energy $\Sigma E_T$ and
other observables in inelastic $\gamma A$ scattering with different triggers.
Our predictions can be tested in proton-nucleus and nucleus-nucleus
ultraperipheral collisions at the LHC and will help to map CFs, whose first
indications have already been observed at the LHC.
