Here's another go at PP. I started out trying to replicate Heartyfisher's edits (which I liked) in PS as a lesson for myself. I then went on to add a few more of my own. I wanted to keep the original framing as I like the detail in the dress and it makes the most of the super-wide angle.
This is what I did:
. Levels - clipped the white point to lighten up the face. small adjustment in black point to give a bit more contrast.
. Saturation - selectively added saturation to the red channel to warm the skin tones and blue channel for the dress. Just a touch more yellow for the grass.
. Cloned out the pole and wires (pretty roughly)
. Lightened the boys face a little
. Boosted contrast a little with curves
. Selected the sky with the magic wand and darkened it a little.
. Flattened and sharpened a touch.
