I've only tried it on two photos and got mixed results too. I drew a rectangle around a power line and it made it worse. The line was mostly still there but it had vertical smudges all over it. Maybe a different selection area will give better results. I'll have to try that.
On a second photo I removed a woman walking along the seashore. I drew a polygon around her and it left some water colour artefacts on the sand part and some remnants of her hair. I drew a rectangle around the first and it cleaned it up a lot. Only some blue remained on a small sandy coloured part on which I repeated the procedure. Only one more was needed to remove the hair remnant. In four simple steps it gave quite an acceptable result.
Hi Bob. The name you gave it missed a few letters at the end possibly due to name length limitations so I changed it to one that fits. Expired is a 'relative' term though.
When in doubt..... Press the shutter.
