Not much to say here. I shot the time lapse on my iPad while I was shooting video segments on my DSLR.
I added music for fun and then had even more fun cutting in to detail shots into the wide time-lapse shot.
Anyone who doesn't shoot time-lapse of one-day (or two-day, or three day) processes like this should. And then they should post the footage to ProTradeCraft
