Adobe Systems Inc. on Monday announced an update to the free Camera Raw Plug-In for Photoshop CS, adding support for the new .DNG format. .DNG is the new “digital negative” format meant to supply an open standard to digital camera raw files. In version 2.3 of the Camera Raw plug-in, support has been added for the Canon PowerShot S60, Epson R-D1, Fujifilm FinePix S20 Pro, and Nikon Coolpix 5400 cameras. System requirements call for Mac OS X v10.2.4 or higher and Photoshop CS. The new camera support has also been added to Adobe’s recently announced Photoshop Elements 3.0.
