In reply to Skyfall:
Hi Skyfall , a good starting place with post processing is Adobe lightroom. its easy to use and gives a lot of potential for developing the image according to your creative idea. there are also other options , eg aperture , viveza , adobe camera raw or capture one. there are books for all of those as well as youtube videos , scott kelbys book on Lightroom is worth reading if you're new to it
hope that helps
