Is it post processing in general you want to learn or is it DPP? As mentioned Canon have some DPP tutorials. You will find more on youtube.


If you are struggling with post processing in general, want to learn about raw files, setting black and white point etc. you could buy and download tutorials from The Luminous Landscape. Try the one about Raw processing. It is a great starting point and you will also better understand Raw processing in DPP. http://www.luminous-landscape.com/videos/download-videos.shtml
