  Understanding the clustering of galaxies has long been a goal of modern
observational cosmology. Utilizing our photometric redshift technique a volume
limited sample containing more than 2 million galaxies is constructed from the
SDSS galaxy catalog. In the largest such analysis to date, we study the angular
clustering as a function of luminosity and spectral type. Using Limber's
equation we calculate the clustering length for the full data set as
r0=5.77+/-0.10 Mpc/h. We find that r0 increases with luminosity by a factor of
1.6 over the sampled luminosity range, in agreement with previous redshift
surveys. We also find that both the clustering length and the slope of the
correlation function depend on the galaxy type. In particular, by splitting the
galaxies in four groups by their rest-frame type we find a bimodal behavior in
their clustering properties. Galaxies with spectral types similar to elliptical
galaxies have a correlation length of 6.59 +/- 0.17 Mpc/h and a slope of the
angular correlation function of 0.96 +/- 0.05 while blue galaxies have a
clustering length of 4.51 +/- 0.19 Mpc/h and a slope of 0.68 +/- 0.09. The two
intermediate color groups behave like their more extreme 'siblings', rather
than showing a gradual transition in slope. We discuss these correlations in
the context of current cosmological models for structure formation.
