  We apply a reflection-dominated model to the second XMM-Newton observation of
the Narrow Line Seyfert 1 galaxy 1H 0707-495. As in the first XMM-Newton
observation a sharp spectral drop is detected with energy that has shifted from
7 keV to 7.5 keV in two years. The drop is interpreted in terms of
relativistically blurred ionised reflection from the accretion disc, while the
energy shift can be accounted for by changes in the ionisation state and, more
importantly, emissivity profile on the disc. A flatter emissivity profile
during the second higher flux observation reduces gravitational redshift
effects, therefore shifting the edge to higher energy. Remarkably, ionised disc
reflection and the associated power law continuum provide a reasonable
description of the broadband spectrum, including the soft excess. Considering
both observations, the spectral variability in 1H 0707-495 appears to be due to
the interplay between these two spectral components. The reflection component
in the second observation is significantly less variable than the power law.
Changes of the emissivity profile, spectral shape and variability properties
(such as the rms spectrum) within the two observations are all consistent with
a recently proposed model in which relativistic effects in the very inner
regions of the nucleus play a major role.
