And if so how. I downloaded the adobe camera raw file from adobe. Put the plugin into CS3 plugin folder? I read on the forums that ACR opens when you click on a photo in Abobe bridge which i tried. I get a file error message stating unsupported format when clicking on the D300 nef in bridge. Do i need to convert the nef first? What I am trying to do is learn how to patch process a group of photos at once.....say sharpen, color correction and white balance all at once if the photos where taken at the same time under the same lighting. As far as i know you cant batch process in lightroom 2 or can you?
