Hopefully this is the right forum to ask this, otherwise let me know and feel free to move it where appropriate.
I set a field blur gradient on an image of my mom and me walking down the aisle (I was doing the photography for her wedding, though I did have to pass the camera off to someone else for this one), primarily because the back ground was a little distracting with the deeper DoF. I've got a pretty meticulous layer mask in place, but even still, the blurring seems to be creating a halo around the mask. Is there any way to counteract this, or is this method of faking a shallow DoF not the best idea? I'm open to any suggestions, and would enjoy learning something new if necessary.
Here's the mask and a screenshot of the image as-is:
Thanks in advance!
