Photoshopping

[Kit-Ginevra]

Any Photoshop genii here? The godkids came round the other day and we took some pictures. We didn't realize until after they've gone that some of the pictures haven't turned out too good- in one, someone's turned away just as the camera shot so we have a really nice pic but with the side of their face, whilst others you can see everyone but they don't look too good.
Anyone who can show how to tweak the pics so we end up with the nice pic and the nice faces together would be much appreciated. Cheers
