TWITCH amplifies
the background of an image by making it twitch (or increase in
saturation or value). A hyper little (or big, if you like) pinch of
distortion scurries about the background, ducking behind the
foreground.
The background and foreground were differentiated in Photoshop, using magic wand tools and marquees and such to make the mask image shown here. The distortion is all computational. |
