HDR image of Castel Sant’Angelo in Rome. It ‘a very ancient roman castle, in the five hundred century it was also used as a prison, now Castel Sant’Angelo is a very important tourist destination.To take this HDR image I put my tripod on the along “lungotevere”, I made three shots through the branches of trees. I processed the image with Photomatix and Photoshop, to eliminate reflections of the sun through the branches I used layer masks with the original and the underexposed shots.
