I'm assuming that there wasn't a body inside of these clothes, well, not a dead one at least - but it did look as though the previous occupier had simply dissolved :)

And I guess that's pretty much all I have to say about this one other than to add that it's a combination of two shots - one exposed for the sky, the other for the foreground - which were then aligned and merged in Photoshop. This is a technique I described in my first Creative Workflow tutorial, but it's pretty straightforward:

1. Copy one of the layers into the other document.
2. Select both layers.
3. Edit → Auto Align Layers (if the originals aren't aligned).
4. Add a mask to blend the two layers (I used a gradient for this one).

As always, I'd be interested to hear your thoughts.
