This final reproduction is an over-saturated, sharpened, over-contrasty variant which some photographers may see as 'sharper' than either the in-camera JPEG or the ultra-neutral, flat ACR export. Adobe Camera Raw was set to 'Auto Adjustments' after first setting Saturation to +20, and was also allowed to set 'Auto White Balance' itself (a subtle shift of hues). The settings it chose were Exposure -.95, Shadows 2, Brightness 101, Contrast +32. A Medium Contrast tone curve was also set (instead of Linear), and the Detail controls were set to Sharpening 25 (the default) Luminance Noise 25 (the default, and not strictly needed, but I let it rip) plus Colour Noise reduction to 50. This is a high setting, not the default 25. The image is not noisy. Why do it? Answer: it removes the colour fringes created by the saturated red channel pixels bleeding off the brightly exposed white shirt edges. Chroma noise reduction in ACR is very useful for removing this type of fine, single pixel colour artefact or fringe without affecting other details in the image. Whether you like this result most or least will depend on your own idea of how digital images should be processed.
