I occasionally would like to output a sharpening mask from LR5 as a file separate from the image, or even as a layer on the image. Anyone know if this is possible? Thanks.
Maybe you could create a virtual copy, remove its sharpening, select both files and Open as Layers in Photoshop. A blending mode (eg Difference) might then get you to the mask, but it's a lot of messing around though. Not sure.
