Detail: Yeah, there are three Detail sliders in the Detail panel (including noise reduction). Confused yet? The engineers tried to come up with a better term, but Detail is at least descriptive. The Detail sharpening adjustment is pretty complicated. When adjusted downward toward 0, the Detail slider kicks in a halo suppression algorithm that limits how strong the halos get with your Amount settings. Halos are a result of image-sharpening algorithms, but the idea is to have the halos be invisible at normal viewing distances. Lowering the Detail slider can reduce the halo visibility. Moving toward 100, the Detail kicks in a deconvolution-based sharpening that is very similar to Photoshop’s Smart Sharpen filter when set to remove Lens Blur. Deconvolution sharpening attempts to deblur an image based on determining what kind of blur is in the image. The processing algorithm uses a point-spread function (PSF) to approximate a mathematical description of the blur and then inverts the PSF to try to sharpen away the blur. Accurately calculating the PSF can be really difficult, but the Detail slider at 100 does a reasonable job of attempting to deblur based on a generic lens-blur PSF. The Detail slider interpolates between these two different sharpening algorithms. The default is 25, but I usually increase this toward the middle of the range (rarely to + 100, though). You should be aware that running the Detail slider up on a noisy image will substantially increase the sharpening of the noise.
