Removing edges from the Lasso tool?

[Tjlicious]

Hey guys.

I've been trying to find the solution to my problem on Google, Youtube and this forum - without any lucky. Forgive me if this is a repost, for my english and for myself being new to all this.

I'm trying to remove the blitz shadow from head and body on a white/grey background, with the Lasso tool. The adjustments with Brightness/Contrast in the chosen area works like a charm, however I

always get a nasty pixeled or whitelined boarder going constantly around the edited area; no matter if it boarders to a black area (shoulder) or a gray one (wall behind person). I've tried to edit the primary/secondary color, with no luck. Any way to make this boarder "blend in" to the new brightness area - or to just remove it? Oh, and btw: The edited area is somewhat identical to the old background, so there is no natural reason to why it should be a constant boarder.

Or is it a better (and easy!) way to remove blitz shadow from a black and white picture?

By which you mean, there is no reason that you could think of in 30 seconds. Just because it isn't perfect for your scenario doesn't mean it doesn't work reasonably well for most other scenarios.

You may want to try one of the effects in my plugin pack. The Effects > Selection > Feather can do what you want.
