Is there any way to edit Lightroom 3.0 images in Photoshop Cs5 ACR? If I choose Edit in Photoshop the image goes directly to photoshop and bypasses ACR. I have tried creating an ACR option in Preferences but cant find the ACR file. Can anyone help?
No...and there is no reason to do so. Lightroom and Camera Raw share the exact same processing pipeline–assuming you are using the same rev version. The only way to take a raw image into Photoshop and use the Camera Raw dlog is to open as a Smart Object which will give you the SO version of Camera Raw inside the Photoshop document.
