![]() The random appearance of film grain gives more attractive results than the regular structure of a digital image, so if you want to use this effect introduce image noise first. Even so, the image has highly saturated colours and brilliant contrast. The effect is extreme, but a threshold of 32 controls coloration. This version results from maximum amount and radius settings. A threshold setting of 11 prevents the filter from breaking up smooth tonal transitions, as the sharpening effect operates only on pixels differing in brightness by more than 11 units. 106).Ī moderate amount of sharpening (55) and a relatively wide radius for the filter to act on (22) improves sharpness where there is subject detail, without bringing out film grain or unwanted information, such as in the subject’s skin-tones. Compare the result of these settings with that of an image that contains a mass of fine detail (p. The result is that film grain and fine detail are sharpened to an undesirable extent. Over-sharpening If you increase the sharpening effect (222 in this version) and reduce the threshold (0), but reduce the radius to 2, virtually everything in the image increases in sharpness. However, the preview window in the dialogue box does not give an accurate view because it samples only the top layer. This method is also effective for sharpening an image overall and can be controlled by direct settings and by opacity. ![]() You can now enter Quick Mask mode or add a layer mask to control which areas of the image will be sharpened by the High-Pass filter. Increasing the radius strengthens the effect (passes higher frequencies, or more detail). ![]()
