Crispy sharpening?

How do you get this crispy sharpening?

I dont think it's the high pass method?

Re: Crispy sharpening?

Filter>Sharpen>Smart Sharpen is all you need to do ANY and ALL sharpening. Superior to HP or other techniques. Depending on the image, you may need to use different radii and settings to sharpen different paarts of an image, but this just means you will need to create one or more layers.

Re: Crispy sharpening?

Smart Sharpen is great indeed, but it has its limitations as well in just being able to "remove" (or better sharpen based on) Gaussian, Lens Blur and Motion Blur.
You might as well sharpen with the "Filter"-"Blur"-"Surface Blur" (a technique that Calvin Hollywood likes to use, I just refined it a little) like I showed here (sorry German only): &
This has the advantage of preserving the edges and therefore you're minimizing the risk of obvious halos.

Although I think, that in this case, Smart Sharpen and a little upped contrast might be well enough :-).

Re: Crispy sharpening?

In this video Flexmanta (Omar) explains how to work with split frequencies, and I'm not sure if he explains how to sharpen an image in this English version video,

but in this other video he shows how to do it with split frequencies, only the video is in Spanish. I guess that you can learn at least something just watching it. Both, pretty cool videos.

Re: Crispy sharpening?

Using the (Apply Image calculated) high pass or Smart Sharpen does just the same (depending on the choice of low pass again).
The only real benefit I can see is that you can sharpen using an adjustment layer instead of having to use a new pixel layer (that's just interesting if you already split the frequencies and did everything you wanted to the image but sharpening).

I don't think that pic is particularly crispy. Well, perhaps it depends on what one understands by cripsy. For me a crispy image is one whose low radius/high freq elements are very sharp and that's not the case here, I think it looks slightly unfocused (like most images).

I have tried to make make it crispier (at the expense of emphasizing the noise a bit) with the gaussian sharpening tool found in Fitswork.

Re: Crispy sharpening?

It looks to me like its more film grain than sharpening.
Make a new layer on top, fill with 50% gray. Run film grain filter set to a level you want. Set this layer to a contrast blending mode (soft light or overlay works best). Adjust opacity as needed. If the grain is too harsh even at a lower opacity, blur at a low radius.
