Try different settings, keeping in mind the image’s output size – small images need more blur than large ones. Choose carefully or, when Blur is applied, the selected region will be left with a distinct margin. Select a narrow feather edge to retain sharpness in the subject’s outline. Select the main subject and invert the selection, or select the background directly, and apply a Blur filter. Another method is to blur the background. You could also paint over the background using the Saturation or Sponge tool set to desaturate. You could also try desaturating the background: select the main subject and invert the selection or select the background and lower saturation using Color Saturation. If you clone from as close to the distraction as possible, this should not be too much of a problem. For example, blue sky can be easily cloned onto wires crossing it, as long as you are careful to use areas that match in brightness and The usual way to achieve this is with cloning – duplicating part of an image and placing it into another part (see pp. Solution You may not need to remove a distraction completely – simply reducing the difference between it and adjacent areas may be enough. At other times, you simply cannot avoid including, say, telephone wires in the background of a scene. Furthermore, though something is distant and looks out of focus, it may still be within the depth of field of your lens. This could be something minor, such as a discarded food wrapper, but out-of-focus highlights can also be a problem.Īnalysis The small viewfinders of many cameras make it difficult to see much subject detail. Problem While concentrating on your subject it is easy not to notice distracting objects in the picture area. Quick fix Image distractions Unless there is a fundamental problem with your image, most minor distractions can be removed, or at least be minimized, using digital techniques. 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).
