Very impressive!!! Thanks for sharing this!

I have the time, but for now I havent seen results that make it worth the investement (for me).

Yeah, not an uncommon response for folks trying it on their own; can be a little bit of a learning curve on processing MF files properly/optimally in their proprietary software...

Guillermo, thanks for the heads up!

It would appear that a new "in progress" open source raw/raster image editor is using the capture sharpening method that you linked to:

http://photivo.org

It seems so: "Gradient Sharpen (Manuel Llorens García). done" in the feedback section. I will ask Manuel if he knows about that software.

Hi folks,

yes it is this filter in Photivo, and today I pushed his microcontrast to the repo (not yet in the win binaries). His microcontrast is really cool, while I have some problems with the sharpening algorithm...

We finally have new windows binaries of Photivo. You can check out this sharpening method on the Lab Sharpen tab as Gradient sharpen. Also his microcontrast is finally there, which works really good on small structures.

Isn't the idea of the algorithm the same as creating a duplicate layer (in Photoshop terms), running a high pass filter on the duplicate to isolate the edges, then blending it in Overlay mode to push the edge contrast?

It's seems the site is down.
Any mirrors or update on that?

This appears to be broken also. Just pulls up a google ad.

Enable JavaScript and have a little patience, and you will end up on the Photivo site. It was intended to be a "joke". Apologies.
