No empty frame?

If you didn’t shoot a frame of the empty scene it’s still possible to create the levitation effect from a single image, but only if there’s enough background detail that can be pasted over the bench. We shot our night-time scene in heavy rain, only managing to grab a few frantic poses before abandoning the shoot. But later on, we found the best pose didn’t have an accompanying empty version (we’d moved the camera between shots). The solution was to clone out the bench using Photoshop’s cloning and healing tools.
