Sharpening
-
I have noticed recently sharpening in ACR is much more subtle than USM in photoshop & results in less of that noticable oversharpening
‘grain’ effect.
Worth experimenting to get to know the difference.
Has anyone any other method of sharpening that offers variations in results ?Hi GS,
I’d always remove/cancel the sharpening slider in ACR – as its ‘destructive’ – by which i mean you can’t adjust it later if you have done more work.
I then do my shapening in Photoshop using the ‘High Pass’ Filter method.
Here’s a quick tutorial.

I use a radius of 2, Blending mode is “Soft light” – then opacity approx 80% – but i can both vary the opacity and radius as needs be – but this works a treat for me always.

I often use the smart sharpen filter set at 1.3 radius. I first make two duplicates of the image, sharpen the 1st copy, add a mask to the 2nd one, and ‘brush in’ the sharpness where required. I saved those steps as an action so it’s fairly quick.

I generally use different methods depending on subject matter, and definitely never in ACR…
well thats not ‘quite’ right, I always use unsharp mask, there’s no point in sharing settings as they depend on the resolution of your camera….
Then the subject matter will dictate what mask I use… so if its a portrait I’ll use an inverted red channel mask with some tweaks in calculations (Obviously I don’t want to sharpen skin tones – unless its a moody b&w of an aul fella with mangy skin that is as much the subject matter as his face!!)
if its a landscape I may only want demarcation lines sharpened (horizon, transitions, buildings trees etc, but not grass sky etc) in this situation I’ll generate an alpha channel based on converting the scene into an inverted line drawing and sending it to duotone in levels
Just my 2c
