Hi Romy. This picture is back lighted but I think the exposure is fine. When I reduce the image size to 1200 before sharpening no halo comes out. When I reduce and do the sharpening the halo comes out and the histogram hits the walls even before I adjust the levels. Please help.
This one looks like you used a large radius USM, Ely. Please re-check your USM values - radius should only be about 0.3 - 0.4 for the posted size.
Its amazing that just by looking at the picture you can already tell what went wrong. You are right instead of 0.3 I had it at 3.0 which is 10 times more and that is why the halo appeared. I was tinkering on that for about an hour and couldn't figure it out. One look and you knew what I was doing wrong. Thank you very much Romy & Mabuhay.
