![]() Using this data, they have designed algorithms that not only take care of some of the curvature and aberrations, but also a way of counteracting some of the softening outside of the more traditional techniques like USM. This allows DxO to understand the "flaws" of each lens, at different focal lengths, focus distances and apertures. What DxO has always done is to test lenses and develop a performance profile of each one. I have upgraded DXO and am quite impressed with "DETAIL > Noise reduction - RAW" (high ISO) function and "DETAIL > Lens Sharpeness." Does anyone know how "Lens sharpness" differs from Unsharp Mask?Unsharp mask is a generic technique that increases microcontrast at boundaries of light and dark areas of the image.
