Please take a look @ screenshot. I've used just two sharpen nodes to sharpen image, one with small one with larger radius. I've set larger amount values to make this visible.
Hi Eneen,there's nothing wrong with the Sharpen node.When setting a large radius, you get this.
You can try using a different one :https://github.com/NatronVFX/natron-plugins/tree/master/Filter/SharpenPlus
is the first column of the image black? that would explain the effect.
No, for sure. Take a look @ screen from Krita:It's simple unsharp mask filter with 30px and 1px radiuses applied twice on 32bit image. Edge is perfectly fine.
can you send me a sample project showing the issue?
