In this study, I use the apparent-magnitude-limited Main galaxy sample of the Sloan Digital Sky Survey Data Release 7 and investigate the environmental dependence of all of the five-band luminosities. To decrease the radial selection effect, I divide the whole sample into many subsamples with a redshift binning size of Δz = 0.01 and analyze the environmental dependence of all of the five-band luminosities of subsamples in each redshift bin. It turns out that luminous galaxies in Mu (the u-band absolute magnitude) exist preferentially in low-density regions of the universe, while faint galaxies in Mu are located preferentially in high-density regions, especially in the redshift range 0.05 <= z <= 0.10.
