I am trying to test the lenses for my Canon 20d digital camera. Then I bring up an image on the screen in Photoshop Elements, on the riht side under settings, when you click on Detail Sharpness is defaulted to 25.
Can someone help me understand this, why 25 is defaulted. Is that supposed to represent "reality"? Would appreciate any and all help. Thanks, Frank
