You can apply Camera Raw as a filter to your already opened image by going under the Filter menu and choosing Camera Raw Filter. Now you can use Camera Raw like usual (the one thing you’ll see missing from it, though, is the Crop tool. When you use it as a filter, the Crop tool doesn’t appear—you have to do that manually in Photoshop, which is why I covered cropping in both the Camera Raw chapter [Chapter 3] and in Chapter 5). When you’re done, click OK and it applies any changes to your image.
