Close to JPEG quality from RFC/PS6

To set SilkyPix to color mode "v4 compatible" you have to click the left icon for color and down there a more detailed choice appears where you can change color to natural and v4.

I use pure detail sharpening set to edge 50 detail 25 borders 0 and in the hidden demosaic tab demosaic to 100 - for RAF in ISO 200.
