If you want to take the good face from one of the images and paste it into the second image, you can make follow these steps.
Open the two pictures in Photoshop. Drag the background layer from one picture onto the other – for my situation I dragged the foundation layer from the picture with two out of the three appearances remedy and dropped it into the picture that has just a single decent face.
You will have a picture with two layers – the best has two good faces and the one beneath has the other one. Close the other picture.
Select both layers in the image that you’re working on and choose Edit > Auto-Align Layers and select Auto.
Photoshop will now align the two layers so that the faces in both layers will be aligned on top of each other. To do this you need to have two images with very little difference between them and this image lined up pretty well as a result.
Click on the topmost layer and add a layer mask to it by clicking the Add Layer Mask icon at the foot of the Layers palette.
The mask is filled with white by default which means that the entire contents of the top layer is visible and the bottom layer not visible at all.
Select black as your foreground color and choose a soft edge brush. Target the mask by clicking on it so you’re painting on it and then paint over the child’s face in the image to reveal the face from the layer image below.
You’ll need to make some small choices about how much of the layer below you reveal with the mask – if you take too much you can paint back on the mask with white to reveal the top layer again.
I made some small adjustments around the child’s collar to hide the fix. The red portion of the image shows the mask – I turned this on – it won’t typically be visible to you as you work.
Finish by taking a critical look at the final image and, if necessary, adjust the mask or add a new layer and clone elements from the layers below to fine tune the image.
I had to do a small amount of cloning of the little girl’s shirt to fix a small problem and then I cropped the image and it was complete.
The entire process took all of around ten minutes.
