I have CS3 Photoshop and Bridge and I just bought a Canon T4i. I can't open my CR2 files. I've searched the forums and it looks like you need Raw 7.1 but I don't think that upgrade works with CS3. Any suggestions on how I can still use CS3 and open my files?
If your camera is supported in a later version of Camera Raw that is not compatible with your version of Photoshop, then you can use the latest DNG converter (free download from Adobe) to create digital negative copies of your images. These will contain all the raw image data. The only disadvantage is that you won't have access to the vastly improved to raw processing that is available in the newer versions.
Hi Canon T4i needs ACR 7.1 which needs minimum of CS 6.
It will not work with CS 3.
So in order to use your RAW images in CS 3, you need to convert them to DNG using DNG converter.
