  We describe in detail the processing of a set of images of the z = 0.42
supercluster MS0302 taken with the UH8K camera at CFHT. The result of this is a
pair of seamless combined V- and I-band images of the field, along with a
characterization of the noise properties and of the point spread function
(PSF), and catalogs of about 30,000 faint galaxies. The analysis involves the
following steps: image preparation; detection of stars and registration to find
the transformation from detector to sky coordinates; correction for extinction
and/or gain variations; modeling of the PSF; generation of images with a
circular PSF; image warping and averaging; modeling of the noise
auto-correlation function; faint object detection, aperture photometry, and
shape measurement. The shear analysis is described elsewhere.
