Sharpening

Bruce Fraser was a World renowned expert on digital photography. He's been dead for a few years now, but his books and articles are still very useful sources.

Here's one on sharpening:

Re: Sharpening

Over sharpened images is one of my pet hates and I see many of them as I visit clubs for competitions.

Some excellent images are spoilt by being over sharpened.

Re: Sharpening

After resizing and any other adjustments for posting, I always do a final 'unsharp mask'. Something like 0.5 radius 125% strength and 7 levels in Photoshop Elements but adjusted on the assumption that it will be viewed actual size on the screen.


I also notice that the better the image in the first place, the less sharpening is required. In fact, if the image needs much sharpening, it was probably badly focussed in the first place!


Sometimes, with a subject that is less than critically sharp, the illusion of sharpness can be conveyed by applying a little Gaussian blur to the rest of the image Also sharpening can be applied to selections, to increase the differential between parts of an image.



With a 'pathological' case, the Nik Sharpener Pro plug-in can do a remarkable job but it's always better to get it right in the first place

Re: Sharpening

Many people think that sharpening is some sort of 'kludge' exclusive to digital images, but not on photographic emulsion images. They don't realise that development of emulsion images is done chemically automatically during the process, particularly with 'high acutance' developers.

Re: Sharpening

True, and don't forget that the term "unsharp mask" originated in the darkroom!
