OK. I was on the right track and had tried this, but its still not quite right.
I am using a rectangle photo on an almost white background. Regardless of the width of the feather setting, the edges of the photo never quite dim to the virtual whiteness I need. i want the edge of the photo to be virtually invisible, as opposed to simply just being lighter.
I want the edges of the photo to appear to start forming out of the background, as opposed to them simply being lighter on the edges.
GollyG. You instruction are clear and I can have a shot at something harder is you have another solution.
tah for now
