That file was processed in Lightroom and, amongst lots of other stuff, it got the standard Adobe sharpening of 1px radius and 25 detail. Here a file that shows what I mean when you zoom in to 100%Īs I mentioned, I didn't take the photo myself. Should I reduce sharpness to a negative value and sharpen the files outside of SPP or do something else? What is the best way to sharpen Sigma files? When zooming in to 100% I noticed that the files looked oversharpened and pixelated even though I left sharpness at 0. I’m close to buying a Sigma camera, most likely the SDQ-H, so I downloaded some raw files today and played around with them in Sigma PhotoPro 6.5.0.
