Good ol' Photoshop.
It's getting late … maybe midnight. Time for a bathroom break ... But wait! What about tweaking this shot just a little bit more first? Then reverse it and put it over here. Hmmm.
It's one o'clock in the morning! Nature is still calling … But wait! Could this area be darkened down a little and added to this other image? Wow! That's starting to work!
It's two o'clock in the morning. Nature's Alarm Bells Sound! Jeez! Better Hurry!!
That's how it goes.
Hal Wilson does this stuff for fun. He is one lucky guy!
