We report on our effort to establish properties of the very high redshift galaxy population by applying optimal photometry and photometric redshift techniques to the HDF and HDF--S WFPC2 and NICMOS fields. We find that cosmological surface brightness dimming effects play a dominant role in setting what is observed at redshifts z > 2, that the comoving number density of high intrinsic surface brightness regions increases monotonically with increasing redshift, and that previous estimates neglect a significant or dominant fraction of the ultraviolet luminosity density of the universe due to surface brightness effects. We present evidence of a population of luminous galaxies of redshift z > 10. We argue that the ultraviolet luminosity density of the universe plausibly increases monotonically with increasing redshift to the highest redshifts yet observed.
