Remove grey pixels around rendered objects

Do you get grey pixels around your rendered images out of Poser or DAZSTUDIO and no matter what setting you fiddled with they won't go away, here's a trick how to get rid of them in Photoshop and Paintshop pro.

Default setting is 1 pixel, increase pixels if 1 isn't enough.

In Photoshop : Layer > Matting > defringe

In Paintshop pro : Selections > Select all > click float > matting > defringe
