Hello,
I would like to share with you new version of Luma Sharpen filter. It produces less aliasing artifacts with better performance.

Here's original filter sharpen layer:

And here's mine:

That second debug screenshot is beautiful. I'm curious, is your new luma shader also implementing a form of anti-aliasing and then sharpening? Or is the lack of aliasing in your version a result of some genius shader writing

?

I guess what i'm really asking is, would we get the same(ish) results by using a form of anti aliasing followed by the old version of lumasharpen as we would by just using your shader by itself?

He's using a different blur kernel than original luma sharpen.

There's no anti-aliasing implemented in this shader, just approach to high-pass filter, or blur as Marty McFly noted, is different.
You won't get the same result with the old version as it implements it's own aliasing even to anti-aliased source. As seen on debug example.

bacondither Offline	This shader is essentially the same as lumasharpen, except using overlay blending for the result and setting the "sharp_clamp" to such a large value it does not really do much anymore. The speed seems to be identical to lumasharpen for me. Have fun experimenting

I tried this shader out for a couple days with Fallout 4. Really like the results and how it looks. Definitely a LumaSharpen alternative.

I used it with Fallout 4 with TAA(Blurry but a very calm picture in motion) and this settings was decent:
Sharpen: 2,400
BT709
Clamp: 0,600
Highpass:1

I gonna check out later how it looks with a game with SMAA which has a lot more creepy crawly pixels in another game. But this sharpener is very subtle and nice.

But I can see how I will use this instead of the LumaSharpen in most cases. Though I like to use LumaSharpen with a low offset bias setting and high sharpen setting. If there was depth-based sharpen tool I would love that. I use selective sharpening in photowork in similar way. And depth based control sharpen would be super awesome. But not sure how it would look in a game.

Thank you, it is a vert nice sharpener on its own. More alternatives is never a bad thing

Kleio420 Offline	what about making two modes for it one just depth based and then a third mode using depth to compare to the original pass to help only sharpen what you want more specifically then just a broad range offered atm?

What do you mean by depth-driven sharpen? Should it leave smooth transitions between foreground-background objects edges, like Panavision lenses vimeo.com/167050590 and sharpen only foreground/background-planes content? Or sharpen foreground and leave background untouched?
I can experiment with both. I just want to know what you imagine the depth-driven sharpening would do.

similar to the edited version of luma sharpen that was made for enb usage was thinking you could use depth as a way to lower the radius of whats sharpened rather then what appears to be applied to the entire image?

Ok, I added depth mask to the shader.

By default it's set to preview mode for the sharpening start and stop.

I also made Panavison-like sharpen version that has Depth high-pass mask.
It gives some interesting results

Zarathustra Offline	Great work. More filters are always good. When I used it for Civ 6, I noticed that it accentuates white edges more than the default LumaSharpen filter, which I prefer in that case. The accentuated bright edges are maybe something to look out for and I guess it depends primarily on the use case and personal preference which filter to use.
