Photoshop turns moving people into ghosts

Interesting work from Aaron Grimes. Sploid writes,

Aaron Grimes used Photoshop to blend regular footage at a 1/50th shutter speed into a new 24 frames per second with a 1-second shutter speed film. The result is, as he says, eerie.

According to Aaron,

What is done here is taking frames from video captured at 24fps with a 1/50th shutter speed and blending them together using Adobe Photoshop. The final product is a video that’s still played at 24fps but with a 1 second shutter speed.

The effect is eerie, causing things that do not move to remain sharp, but anything with motion to blur. The faster something moves to more faint it becomes. Where this is best shown is when something changes speed such as the shot of the man stopping in the street to check his phone, he almost appears out of nowhere, but when he walks off you can see his shape fade away.

    OK, so how exactly is that done. Amazing effect!

      Yep! – truly spellbinding.
      My guess. The original footage has been deconstructed. (You can do that most easily in After Effects – the clips are simply transformed into sequences of still images.) Then some of these images – a selected set – have been blended to make the new frames. (This can be done either in After Effects or Photoshop – it’s pretty tedious work at this point, but Batch Processing in Photoshop is a bonus.) Finally then there was a reconstruction. (This is just a simple video rendering of the new frames. I did not know that you could do that in Photoshop directly. But After Effects is fine as an alternative, with more flexibility.)
      Here is an attempt at something different (visually), but with this type of workflow: http://www.behance.net/gallery/In-Descent-from-Art/12963735
