The camera raw filter is very powerful tool. Not only can you use it to fix all kinds of photo problems like exposure, clarity and color but it can be used for portrait retouching too!
Here is a before and after photo that I used the camera raw filter on. It only took about a minute and was quick and slick.
If you overdo an adjustment, just undo CNTRL/CMD Z and adjust the slider as to not make such a dramatic difference.
Who knew the Camera Raw tool could be so versatile?
