I often need to just blur the edge of an object i cut out from one image and pasted into another to make it look more realistic. Basically i want to make the edge less crisp. I find using the feather option does not give me enough control and when using a mask, i still don't feel like having the right options in the refine mask menu. Is there a type of blur that would give me more control to just blur an edge? Ideally with options such as how many pixels from the edge i want to blur, how much blur i want to give it, how much choke and so on.
