Photometric redshifts: a glimpse of the future

Alex Szalay, The Johns Hopkins University

Photometric redshifts are becoming increasingly popular. The talk
describes, how the technique goes considerably beyond just providing
a redshift estimator: it is possible to get an estimate of the galaxy
spectral type as well. Comparisons between different photometric 
redshift estimation techniques will be presented. New approaches to 
photometric redshifts are also discussed. New surveys with 100 million
galaxies provide new and interesting ways to use photometric redshifts.
