7 When you are happy with your paint job you can apply some blur
or try one of the artist filters to change the way the edge looks. I'm
pleased with the straight erasor brush version and won't make any further
But, before you flatten the image why not save the work you've done so
you can apply it to other same size images in the future?
8 With the border layer active click inside the white frame area
using the Magic Wand tool, making sure the tolerance setting is 1 pixel.
Then go to Select>Save Selection. In the pop up box call the selection
something that makes it recognisable (I named mine ragged edge 1) This
will save your work as an alpha channel. Then when you want to apply the
border to a new photo open the new one and this one. With the new one
active go to Select>Load Selection. From the drop down list in the
source box choose the photo that you saved the selection in and pull up
"ragged edge 1" from the channel box. The selection will appear
on your new photo providing you have both pictures in the same orientation
and saved at the same dimensions. All you have to do then is go back and
redo step 4 of this tutorial to apply your border.
