I used Canon Rebel T4i for photo shut and it gave me CR2 files. I need pictures in RAW quality. Now I have a problem to read those files. My operating system is Mac OS X Snow Leopard version 10.6.8. Photoshop version CS4. I installed Camera RAW 5.4 and Adobe DNG Converter. Now looks like I can convert CR2 to dng and see it in iPhoto, but my Photoshop still can't recognize CR2 and dng files. None of my other software can read those files. What you can suggest guys?
