First lets say i know most will say i do it wrong, i should use layers etc, but photography should be fun and this is the way i enjoy doing PP.
Where i do a lot of shooting it can have a very distracting background and can get a bit bird busy, here is a before example.
To get the image how I want it using Photoshop the raw is first loaded into ACR and I click auto, if i like the result i then open in photoshop.
For this image I did, the resize first as my computer can be slow, 1024 on the long side.
Cloned out all the OOF birds using content aware
Leveled the image
Then did a crop extending the canvass anywhere I felt it needed.
The empty canvas areas where filled using content aware
Subject select was used on the bird and then inverted.
Lens blur was used on the background
Resized back to 1024 due to canvass extension
