Here are two approaches to fixing over-sharpened images in Photoshop. Both rely on the blending mode you are using.<\/p>\n
The first is “before the fact” – that is, if you have not sharpened the image yet, do this:<\/p>\n
1) duplicate the image, which will place an identical copy above your base layer.<\/p>\n
2) do your sharpening on that duplicated layer. If the sharpening produces the dreaded white halo, do this:<\/p>\n
3) set the blend mode of that over-sharpened layer to darken;<\/p>\n
4) zoom into a problem area and set the opacity to about 66% to start.<\/p>\n
5) watching the screen, adjust that percentage as needed.<\/p>\n
Using this technique, you may end up with some pixel size darker artifacts, but they will, in the finished print, be basically invisible.<\/p>\n
6) you may need to add a gamma adjustment layer to finish it off.<\/p>\n
This approach saves considerable time when the halos are many, and spread throughout the image.<\/p>\n
If instead you have the halos around mountain or roof-tops, or similar dark vs only slightly less dark areas, or you only have an ill-sharpened image, then you can fix the image without resorting to a new layer.<\/p>\n
Using pretty much the same method, do this:<\/p>\n
Using the clone stamp tool, create a brush that is soft-edged and 3 or 4 times the size of the halo. There is room for “slop” in this, and since you’re going to trace over the halo, you might as well make it easier with a larger brush.<\/p>\n
Option click to select the source from the LIGHTER of the two areas (but not the halo itself.) For example a lighter sky with a darker roof-top. Option click the lighter sky.<\/p>\n
Then set the blending mode to darken, and simply brush away the halo.<\/p>\n
If you have been pixel-peeping to fix halos, either of these techniques will truly make your day.<\/p>\n","protected":false},"excerpt":{"rendered":"
