workshop task- borders

here is how to create a border using ocean ripple or the blur technique.
Ocean ripple: to create the border, select the rectangle marquee tool and make the rectangle a border you wish to have , now inverse the rectangle so the out side of it is selected. now feather the image to 150. after this go to filters and select ocean ripple.here you can change the amount and strength of the filter. I feel a higher amount is best.now press the erase tool -eraser tool needs to be selected from the left hand tool bar and the selected area erased. Once you have erased the area you need to deselect the area. To do so click on Select --> Deselect, and you'll be left with your final image.

blur: to do this do the same as for the ocean blur, up till you pick your filter. here select blur, gradient bur. You will then be presented with a window in which you can adjust the amount of blur you want. after this you can deselect the rectangle, giving you a border made of the edge of the original image just blurred. or you can erase the edges like you did for the ocean ripple border. giving you a plan border that merges with the edges of the image in the middle
