Selection tool lines

I'm trying to make a selected region darker. To do this I'm trying to cut a piece of the photo out to a new layer and change the colour mask of that layer, but when I try to cut it out, it leaves this white line in the photo where it cut. Any ideas how I can avoid this?

The clue is in your post, you are **cutting** then pasting over in a new layer. This leaves a legacy of anti-aliased (semi transparent pixels)

see for the cut http://i.imgur.com/9DLb9dM.jpg

One solution is to turn off anti-aliasing **before** making the selection, which while giving an 'invisible' join http://i.imgur.com/XKPxRL3.jpg

Makes a horrible jaggy border when the selection is color adjusted. http://i.imgur.com/9jsG4CM.jpg

A better way is keep anti-aliasing **on** then COPY **not cut** then paste. That will give a better border when color adjusted. http://i.imgur.com/Mb6ul1x.jpg
