Greetings! I have searched and haven't found what I am looking for. I shoot RAW and process with DPP. I have found tutorials for DPP but they are all very basic. What I mean is that they show you around the GUI but I want to know what they tools are actually doing. For instance, there is a sharp/unsharp mask option on the first tab. What is the difference? Then there is another sharpening that you can do on the RGB tab which has an entirely different scale. What is different between the contrast on the RAW tab vs. the RGB tab? etc, etc. I don't understand all this.
So if someone could direct me in the right direction, I would be most appreciative.

!
