A good way of learning digital photography is knowing the basics. Lot of photographers talk about technical settings of digital camera and it is overwhelming.
I found videos of Thorsten von Overgaard who explains the history of photography . These basics of photography are relevant to the digital camera photographer today as it was to a film photographer long time ago.
What is Sharpness in Photography ? Sharpness is about getting great detail of attention on the photograph.
Aperture is a way to increase the focus. And it is a way to change the exposure
