Adobe has released Photoshop Lightroom 3.4, a maintenance update that adds support for the raw image formats used by several recent cameras and incorporates a host of bug fixes. Cameras added to this update include the Canon EOS 600D (Rebel T3i/Kiss X5 Digital) and Canon EOS 1100D (Rebel T3/Kiss X50 Digital); Fuji FinePix S200 EXR, FinePix F550 EXR, FinePix HS20 EXR, and FinePix X100; Hasselblad H4D-40; Kodak EasyShare Z990; Nikon D5100; Olympus E-PL1s, E-PL2, and XZ-1; and the Samsung NX11. Bug fixes range from problems uploading to online photo-sharing sites to fixing a color cast on Nikon D7000 or Pentax K-5 images under certain circumstances. Adobe also released the free Camera Raw 6.4, which adds support for the same cameras for Adobe Creative Suite 5. ($299 new, free update for owners of Lightroom 3, $99 upgrade from earlier versions, 88.6 MB)
