  We present Bivariate Brightness Distributions (BBDs) for four spectral types
discriminated by the 2dFGRS. We discuss the photometry and completeness of the
2dFGRS using a deep, wide-field CCD imaging survey. We find that there is a
strong luminosity-surface brightness correlation amongst galaxies with medium
to strong emission features, with gradient $\beta_{\mu}=0.25\pm0.05$ and width
$\sigma_{\mu}=0.56\pm0.01$. Strong absorption line galaxies, show a bimodal
distribution, with no correlation between luminosity and surface brightness.
