We have developed a method for producing projected photometric images for the outputs of the hydrodynamics code Enzo. Population synthesis models are applied to the Enzo stellar particles to produce synthetic spectra and broadband fluxes for each star particle. Projecting these star particles' positions and applying a dust attenuation prescription we produce realistic two-dimensional images in different filter bands. We apply this method to the outputs of a cosmological cluster simulation at z 0 and extract photometric information pertaining to individual galaxies present in the cluster. We compare the resulting data set with the photometric properties of a subsample of cluster galaxies that have been observed with GALEX, SDSS and 2MASS. In particular, we use our knowledge of the formation history of each simulated galaxy to relate the observed properties of galaxies to the physical processes driving their evolution in dense cluster environments.
