A friend posted this neat set of steps in Photoshop. I suggest cropping to a square but rectangles can look good too. I have made an Action that you can add to Photoshop > Presets > Action. It stops at the last step so you can still adjust the blending modes before Flattening all layers. If you email me, I will send it to you. susanbaileyphoto@gmail.com
- Open you photo in Photoshop > unlock background
- Go to filter >pixelate >mezzotint >medium lines
- Go back to filter >blur>radial blur 100% >blur zoom quality best
- Repeat steps 3, 3-5 times
- Duplicate layer and turn duplicate layer off (eyeball)
- Highlight and work on original photo layer
- Filter>distort> twirl (angle value plus 80% or how you desire
- Turn on other layer and filter>distort> Twirl >Angle value minus 80% or as desired but it will be opposite of #7
- Alter duplicate layer blending mode to lighten on screen
- Experiment with other filter and blending modes
- Flatten layers
