My way
Go to  "Image Size " Setting the desired value

Bicubic (best for smoth gradients)
or
Bicubic Sharpen (best for reduction)

next UnsharpMask Amount=150, Radius=0,2 Th = 0

next
-SaveAs
-ICCProfile = off

And it is very bad image in Photoshop  looks great in the browser is awful (very sharp and much ghosting)

I almost always do my sharpening on the full sized image, usually with an edge mask (action I picked up on MM) and unsharp mask.  I ignore the "preview window" and look at the actual image at 100% when judging how much sharpening to apply.Then image size using the "best for reductions" option and have usually been pleased.  Sometimes this can look too sharp and I re-work it with less unsharp mask.

Not saying this is best, it's just my habit.

For web uploads I use this PS script to downsize and resharpen images:

Bicubic Sharper (best for reduction) adds the effect of little bit of uncontrolled sharpening. I like to use it at times to counteract the Resampling effect of some websites like facebook for example. If you upload the larger image to FB it tends to use its own Resampling to make it fit FB dimentions and in the process they often soften the image so using Bicubic Sharper I can add sharpening I know will be reduced by FB and gave me altogether approximate version of what I want. In some other cases I want to apply sharpening myself in more controlled conditions.

Wouldn't that be context specific? Every image is different and you did not mention neither the new pixel dimensions nor the final use. But as a general rule final output sharpening should be applied after Resampling, yes.

Why do you strip away the ICC Profile? Unless you have specific and most likely very questionable reasons to do so I would advise against it.

Thanks Krunoslav !!

I think the reason lies in the fact that the different sites in its pre-rendered image, singing and there are differences
USM  settings are approximate and for each image are different.
Thanks for the video

PS When will your new DVD?

Is there a way to translate your site into English? I'd like to browse your website some.

Hey guy's. I just wanted to note that the credit for the web sharpening script should go to Andreas Resch - it's his script and website :-).

As I said the download includes a detailed English version for the settings. You could try Google translate if you need his page in Englisch http://bit.ly/X15XfA. It's well...gives you at least an idea what he is talking about :-). Here is a Google Translate version of his original article describing the method: http://bit.ly/ZskfT2

In general what the script does is the following:

Reducing the size in several steps. After each step the image is sharpened relatively strong to compensate the softening through reduction. The number of steps depends on the original size and the final size. Die image size of the in-between images is always 1.66 smaller than it's predecessor. The sharpening is done in LAB mode. It uses edge mask sharpening for highlights and shadows.

If you need more information I would recommend contacting Andreas.
