I always open files as smart objects. When I sharpen a photo in ACR and open in Photoshop the sharpening doesn't appear; if I reopen in ACR, the changes I have made to radius are there, but the stregnth is zero. I have tried this on numerous photos, and have reset preferences...still the problem exists. The sharpening function used to work. Now what? Thanks!
I'm using a Mac Pro, with the most current version of Photoshop CS4.
