I picked this one for Michelle's expression.
Then I added Grace from another frame
I did a little bit to soften the fly-away hairs and lines on the faces. I try to be gentle when I'm retouching because I want my subject to look like real people (for the most part).
The fun part is selectively adjusting the contrast and saturation for each part of the photo. Generally, I'm gentle with skin tones, so I can keep a good tonal range. I'm a little bit rougher with clothing, props, and anything else that I really want to pop. I then crop the photo and do a bit of burning around the edges for a vignette.
I may end up taking this photo a little bit further. I'm also considering using a different frame for Grace; which means I'll be starting over for the most part.
