  The Carnegie-Irvine Galaxy Survey (CGS) is a comprehensive investigation of
the physical properties of a complete, representative sample of 605 bright (B_T
<= 12.9 mag) galaxies in the southern hemisphere. This contribution describes
the isophotal analysis of the broadband (BVRI) optical imaging component of the
project. We pay close attention to sky subtraction, which is particularly
challenging for some of the large galaxies in our sample. Extensive crosschecks
with internal and external data confirm that our calibration and sky
subtraction techniques are robust with respect to the quoted measurement
uncertainties. We present a uniform catalog of one-dimensional radial profiles
of surface brightness and geometric parameters, as well as integrated colors
and color gradients. Composite profiles highlight the tremendous diversity of
brightness distributions found in disk galaxies and their dependence on Hubble
type. A significant fraction of S0 and spiral galaxies exhibit non-exponential
profiles in their outer regions. We perform Fourier decomposition of the
isophotes to quantify non-axisymmetric deviations in the light distribution. We
use the geometric parameters, in conjunction with the amplitude and phase of
the m=2 Fourier mode, to identify bars and quantify their size and strength.
Spiral arm strengths are characterized using the m=2 Fourier profiles and
structure maps. Finally, we utilize the information encoded in the m=1 Fourier
profiles to measure disk lopsidedness. The databases assembled here and in
Paper I lay the foundation for forthcoming scientific applications of CGS.
