We use an automatic algorithm to fit two-dimensional bulge and disk surface brightness profiles to a sample of 200 Sloan Digital Sky Survey Early Data Release (SDSS EDR) galaxies of known redshift and brighter than r=16. The bulge-to-disk (B/D) luminosity ratios can be combined with an estimate of the galaxy's local environment to address a number of key issues that are central to our understanding of galaxy formation: – How do B/D ratios depend upon galaxy luminosity? – What are the disk and spheroid luminosity functions for field galaxies? – How does the total luminosity in bulges and disks depend on environment?
