A posting in the forum pointed me to a description of an interesting way to sharpen an image. This Octave Sharpening is useful when you have to do a lot of sharpening and want to avoid the typical halos around the edges.
The secret lies in a combination of 4 USM sharpened layers with different opacity. As in the recipe I used an amount of 5 (500% in the Other Program), threshold 0 and 0.5, 1, 2 and 4 in the different layers. The opacity was set to 100%, 50%, 25% and 12.5%. The more sharpening the less impact in the image. But the traces of harsh sharpening give a bit of a gradient to the edges in the final image.
Norman needs some information about old slide producers in Israel. Are you able to help?
And I have started to use Google Wave for episode planning. If you want to participate, drop me a line at info@meetthegimp.org . I also have some invites.
