Tip: Print It On Canvas
If you really want to “sell” the effect that this image was painted with oil paint, do two things: (1) sign it, and then (2) print it on canvas.

Field Blur Filter: F/1.2 Bokeh Background Effect
This is a really cool filter effect because it lets you add a super-shallow depth of field to your image and lets you place the focus point, and the blur, right
where you want it. This is kind of designed to emulate the soft-focus, shallow depth-of-field from shooting a telephoto lens with a wide aperture (creating a
bokeh effect when you have bright areas in the background).

Step One:
Open your image in Photoshop, then go under the Filter menu, under Blur Gallery, and chose Field Blur. This brings up the Blur Gallery workspace and
places a blur pin on the image. What we’re going to do is use pins to keep parts of the image sharp (like the parts of our subject that are closest to the
camera), and then add a mega-blur to other areas, including parts of our subject that would be a little out of focus, like her ear and the back part of her hair.
