Is there a "lasso" to select only one part of an image in Apple Photos?

I have an image with the subject in the foreground and a bright background. The face is in shadow. Even with the Shadow adjustment at maximum high, the entire image is too bright and the face stays in shadow. In Photoshop, I could select a part of an image and apply adjustments to just that part. I could also apply an adjustment using a brush. What is the solution to correcting this image? The photo is too good to simply throw away--and, in the current state, it is a throw away. Help me from crying really loud.
