USE SMART OBJECT RAW FILTER
Many people prefer Adobe Camera Raw's interface to the regular Photoshop layout. For photography, without any complex layer blending or compositing, it’s arguably everything you’ll ever need. However what if the image that you want to edit isn’t a Raw file? Are you stuck with regular Photoshop at this point? Well, no – you can still use ACR in fact. With your image open in Photoshop and your image layer active in the Layers palette, go to Filter> Camera Raw Filter. This opens up the image in ACR no matter what file type it is. Now, this doesn’t miraculously give you the ability to edit JPEGS as if they were Raw files – you’re still under the editing limitations of JPEGS, however you can enjoy the simplified interface and powerful tools no matter what file type you’re working on! It’s worth noting that once you click OK in ACR, those changes are then ' baked' into the image, and can’t be re- edited or undone, unless you follow the steps below to convert for Smart Filters first.
