... a technique I'm working on at the moment.
The original picture is not mine - it's an image on my computer screen, but the effect is to then photograph it and introduce dynamism to the image. I'm hoping to use this technique to work on some fencing photographs which are literally just pictures, taken at wide aperture and fast focus. They're static snaps and need some flow.
You could almost certainly do this in Lightroom or Photoshop, or something, but working with an actual camera to re-take the shot after the fact lens a certain randomness into the effect which clinical darkroom software would never be able to reproduce.
Needless to say, it felt a lot like pot-luck to start with but I think I'm starting to hone this as an actual skill.
