Hi, The .CR2 extension identifies the file as a proprietary Canon RAW file. For each new Canon camera on the market, Adobe has to implement support for these proprietary formats like .CR2. Just because a new Canon camera uses a .CR2 file type doesn't mean it is automatically supported by Adobe software or by RAW processing software available from other software vendors. The same is true for other cameras like Nikon, Olympus, etc. They each have their own proprietary RAW format that Adobe must write new code to support. There is engineering work necessary to make this happen. This often involves us getting physical camera units from the manufacturers and working directly with them to add support. We do our best to issue new camera support releases as often as possible. Some camera vendors choose to write out .DNG images, which is an industry standard RAW file format Adobe has made freely available to help facilitate what you are asking for. This is why it is often suggested that for older versions of Adobe Camera software, using the free DNG converter provides a way to open and edit RAW files from newer cameras without having to update your Adobe Camera software. DNG files are RAW files just like .CR2, but they are backwards compatible with older Adobe camera software and with many older versions of camera software from other vendors. Converting images to DNG can be set to happen automatically on import in applications like Adobe Bridge or in Adobe Lightroom. If you have .CR2 files from a specific Canon camera that were able to be opened in a previous version of your Adobe software and now they will not open, then that is a different issue that someone here can likely help you with. Hope this information was helpful. Regards, - Chris
