![]() ![]() This way a similar perceived sharpness is created with tighter halos. Instead, the peak before the shadow valley (red arrow a) is pushed up and the valley after the highlight peak (red arrow b) is pushed down. The "squeezing" of the affected pixel range from 13 to 9 pixels does not result in the pushing down of the "shadow valley" or pushing up of the "highlight peak". The graph translates the brightness of the pixels into heights.įor the same radius, Lens Bblur affects pixels in a tighter range. This theoretical example shows the difference between the Smart Sharpen "Gaussian" algorithm, (which the regular Unsharp Mask uses) and the new "Lens Blur" algorithm. ![]() The above exaggerated theoretical examples were sharpened twice with sharpening parameters which are not recommended in order to make the differences between the two methods more visible. Compared to the third image, the second image has initially more sharpening in the darkest shadows, then about the same, and then sharpening becomes gradually weaker as you move to the highlights. The second image is the first image after applying smart sharpening to the shadows only, while the third image is the first image after applying the conventional unsharp mask. The first image is the original before any sharpening is applied. ![]()
