How much sharpening

[Laurie Caddell]

Hi everyone, just checking to see how much USM people use on the average S2 RAW or non-processed jpeg shots. A few people seem to think that 500/0.3/1 is a reasonable amount, but I find artefacts appearing at that amount.

Also, for those who have seen my posts complaining about my 24–85 'G', just to let you know I'm getting a 24–85 'S' next week so will update you all soon!

Many thanks

I use 49, .7 and 0, once, sometimes twice on my images. There's a whole thread somewhere here on what people use though.

Lots of good advice in that thread. But for a down and dirty approach, as suggested by his eminence, Mr. Thom Hogan; try this two step:

First sharpening: 175% / .9 radius / 0 threshold / fade sharpening > 100% > Luminance

Followed immediately by:

Second sharpening: 100% / .4 radius / 0 threshold / fade sharpening > 100% > luminance.

The fade is mine and thrown in cause I read it somewhere and it really helps. Of course it all depends on how you captured the shot and the lens used in the first place. If camera is set to no sharpening you might increase the above values, especially the first step. If camera set to 'sharpen' you'll need less. Works great most of the time.

I have used most of the techniques discussed and use all of them for different sublects. The amount of sharpening also depends on the final output. For web you don't need anywhere near as much sharpening as you do for hi res photo quality images. Basically the higher the dpi the more sharpening is required to get the same result.

I have no set number... every photo doesn't need the exact amount of sharpening - some more than others. Also, I sharpen the whole picture - and then I add extra sharpening to the eyes.
