Bokeh Overlay on Photograph

1.  Open both your photograph and your plain bokeh image that you took in photoshop.

2. Using your move tool, drag the bokeh image ontop of your photograph.

 
3.  Click Control T and drag your photograph to fit over your image if it is to small or to big.

4.  On your layers pallet where it says Normal, change it to Overlay.  You can also try some of the other blending modes like soft light, hard light and mulitple to see what you like best.

5.  Click on the little camera at the bottom of the pallet to add a clipping mask.  The mask will be white.
 
6.  Make sure you have a black brush.  Begin to paint of parts of the bokeh you do not want.  
 
7.  If it is taking off to much, pull down the opacity at the top of photoshop.  
 
8.  Once you have finished this part you MUST edit your photo with different adjustments to get a clean finished photograph.
