This is a teaching shot I made nine years ago in the Palouse. It is deliberately under-exposed so I could use it in a book on post-processing.
This is the same shot completely post-processed in MacPhun Luminar. It took me less than 45 seconds. Proof is in the pudding as they say.
If you want your own copy of Luminar, visit http://bit.ly/MacPhunSoftware. I can save you $10 - use the code PHOTOPLUGINS - it's probably the best post-processing software for the money that you can buy. Sorry Mac only for now but this year they say a Windows version will drop.
