Yes, but if you are resizing drastically, like making a small version for posting, the resizing will cause a loss of sharpness, so no matter how good the original looks a second sharpening will be needed. DPP is coming along, but it is still far from the sophistication of LR's size aware output sharpening.

Now Elie, you know I'm a long-term LR fan, but I do enjoy boosting any advance of DPP -- it's all good:)!

It certainly is. Actually I intended that post for the benefit of newbies (I hate that word, make it "beginners") who might wonder why their perfectly sharpened images in DPP might not look as good on the web.

I don't know. According to the names, Strength is a synonym for Amount and Fineness is exactly what Radius controls - whether the effect is spread over a finer or broader strip of pixels. The problem I see is that radius expressed in pixels is an exact number (well, almost exact even if we don't know the formula for calculating 0.5 pixels) but with DPP's USM the 0-10 scale numbers could mean anything. But it is a very nice upgrade and from the little I have played with it I really like it.

Your logic is what I thought it SHOULD be but Fineness SEEMS to have greater effect than Strength...unless I'm seeing/using it incorrectly.

It's really not that complicated. When you resize an image, you simply resharpen it to your preference.

Very true, but people aren't born knowing that (unless you accept the Socratic theory of education.)

Has anyone done any real experimenting with converting/resizing then using the new Unsharp Mask for the Web, and have you seen a noticeable gain? I've been so Lightroom-centered I've just used DPP for quick conversions and not messed with output sharpening with DPP like that, so it would be cool to hear from some serious users.

Hey Tony,

I normally do all the editing first before converting and resizing it.

Yeah, I'd say most people do, so I'd be curious about those who do "output sharpening" after converting and resizing. LR has output sharpening that is applied at the point of converting/exporting, it'd be nice to see if/how people may be approaching something in DPP. Of course, a lot of people are in the "Photoshop for output sharpening" approach, but for Web use that could be overkill if we can cook up alternatives in our Raw processors! I still have my Photoshop actions for stuff like resizing, sharpening, converting to 8 bits, sRGB and Saving the jpegs, all that I used to use to pump out stuff for the Web, but Lightroom has spoiled me and I never use them any more, and it'd be cool to see what people are doing with DPP!

But you can't use" unsharpen" for JPEG images in DPP...

Right. I think this only applies for RAW images. :cool:

But you can't resize RAW images in DPP. So I'm a bit confused by some previous posts where people seem to think they can resize/output an image and THEN sharpen it afterwards. You can do that with DPP since it also allows you to sharpen JPEGs, but not using the new Unsharpen feature.

Just confused by the posts above, that's all...

Ah, you know, you are right -- I didn't even think about that! That's what I get for thinking without thinking:)!

Interesting, never realized that because I'm always editing first.

But I can crop first, edit and then resize. But I guess cropping is part of editing. Ack.
