Using the Hyperz code (Bolzonella et al. 2000) we present photometric redshift estimates for a random sample of galaxies selected from the SDSS/DR7 and GALEX/DR4, for which spectroscopic redshifts are also available.

We confirm that the inclusion of ultraviolet photometry improves the accuracy of photo-zs for those galaxies with g* – r* ≤ 0.7 and zspec ≤ 0.2. We also address the problem of how binary interactions can affect photo-z estimates, and find that their effect is negligible.
