Just purchased Nikon D610 and when trying to open raw images in Adobe Camera Raw I get this message : "The Photoshop Camera Raw plug-in did not recognize the format of 1 or more files. If these files are from a camera, you may need to update your version of the Photoshop Camera Raw plug-in. I am currently using Photoshop CS5. I had no issues with my Nikon D300. Thanks in advance for any help!!!!!!! Desperate!!!
Raw files are different for every camera make and model. As new cameras come onto the market, Adobe has to update the Camera Raw plug-in used by Photoshop to read the Raw files. It's a never-ending story of perpetual updates.
The D610 is supported in Camera Raw 8.3 and later which is only compatible with CS6 and Cloud versions. CS5 will never be able to open those Raw files.
The D300 is supported in Camera Raw 4.3 and later which is compatible with CS3 and later. Hence you can open those Raw files in CS5.
