Earlier this evening John (theMusicMan) hosted a very useful live online tutorial on using the High Pass Filter in Photoshop/Elements for sharpening.
It just so happened that I was struggling with an image I'd made today at Hatfield Forest, using my 9-18mm at f11 at ground level to get a (hopefully) dramatic worm's eye view of the buttercups surrounding a large oak. Due to poor focusing technique I had a problem with DOF. Even f11 was insufficient to give DOF from the nearest flower to the tree in the background. I should have either used a smaller aperture (which would have risked degrading the image with diffraction) or weighted my focus so that either the tree was sharp, with deliberately OOF blooms nearest the camera, or made the foreground really sharp at the expense of the tree.
As it was, all I achieved was a rather unsatisfactory compromise where both background and extreme foreground were not quite sharp. Sharpening in Elements using my usual method didn't really work, so I wondered if the High Pass Filter would be more effective. Here are the results:-
Sharpened USM
Sharpened High Pass Filter
If the image is badly OOF no amount of sharpening of any kind will save it. However, in this instance I think it has made an improvement over my usual method. What do you think?
Thanks again, John, for this very useful tutorial.
