Ken the edge was quite easy in PS. Using the Rectangular Marquee tool select the whole image, go to " edit " then down to " stroke " select color black and in this case 50 pixels for stroke width. Once the border has been placed on the image select edit again and use the " Fade " function until your happy with result.
