After buying the Canon T2i, I realized that the files (CR2) won't open in PS. I did my research and found that the dng converter was the thing I need. Unfortunately, the converter won't recognize and convert the CR2 files that I try to convert.
I am guessing I will probably get a reply telling me I should have done my research before I bought the camera (as I have seen in other forums), but I am hoping for a more productive (and less offensive) answer.
The DNG Converter and the Camera RAW Plug-in and Lightroom all use the same Adobe RAW Engine which must be updated for each and every camera's RAW format.
The last DNG Converter was released in December and the T2i was released in March so the T2i won't be supported until a new DNG Converter comes out which I wouldn't expect to be too much longer, probably within a month; however, what is not clear is whether the new version of the Adobe RAW Engine that supports the T2i will be in ACR 5.7 with CS4 or ACR 6 with CS5.
I see a lot of answers speaking about having the most up to date version of the Camera RAW Plug-in. I have a similar issue with my .CR2 files... I cannot open them in Camera RAW because it tells me that my camera model or make is not supported by the Plug-in, and so I was directed by other forums to just try converting the .CR2 files to .DNG. I already had the Adobe DNG Converter (version 6.5 I believe), so I tried this. It too told me that my files or camera make were not supported. However, I have always been able to successfully both open my .CR2 files AND convert them to .DNG. I had not updated anything on my camera nor on my Adobe programs and for some reason this last attempt to open RAW files failed me... I have no idea what change would have led to it. Luckily I shopt in both RAW and Large JPG but I certainly don't want to rely on my JPGs of course... Any idea why this problem might have arisen now if it had always worked easily in the past?
It doesn't help that files are called NEF & CR2 etc. because they are NOT the same.
Each new camera has its own new raw format, which older software does not understand. The extension is irrelevant.
Camera manufacturers really ought to sort this out, and could always adopt DNG as a standard format to avoid this malarkey every time a new camera is released.
You can always convert all supported cameras' raw files to DNG using the latest DNG Converter, which is currently 7.1 RC and is available from Adobe Labs: http://labs.adobe.com/downloads/cameraraw7-1.html
