Open JPG in RAW: I’m sure that all the cool new options in Camera Raw haven’t gone unnoticed to you. Don’t you wish that these options were available to all images? Good news, they are. You can now open Jpg and Tiff formats inside Camera Raw and make use of the tools. Right Click on the Image in Bridge and choose: Open In Camera Raw. The jpg or tiff is now open in Camera Raw ready for all the cool tools. Remember though, if you want to take full advantage of the Raw tools, you should shoot in Raw on your camera.
You can do that inside Photoshop Goto Edit > Preferences > Camera Raw > JPEG and TIFF handling and choose Automatically open all supported JPEGs
