Hi Andy, have you got more info on this, it works so well..regards tao


'Scott - I would submit that it's not the camera but the contrast in the image - this affects perceived sharpness and the contrast is usually higher with good light than low light. Have you tried LCE (local contrast enhancement) - it's a form of USM using a large radius (30-50 pixels) and low amount 10-30% (adjust to taste) - it can do wonders for a "soft" i.e. low contrast image and will make it "look" sharper....'

I learned about it from Michael Reichmann who learned about it from Thomas Knoll , the original author of Photoshop 1!
I am now getting into the habit of adding a little LCE for some lenses (occasionally quite a lot if it was a soft foggy day, for instance) before I use USM in its more conventional mode (i.e. lower radius, higher amount) Still learning how noise is affected by different levels of LCE and playing with a non-zero threshold.. It's probably better to do this after noise reduction (I'm still hoping Neat Image or Noise Ninja will materialize for the Mac!).
Keep on playing, keep on learning!
Andy
