Quite incredible yeah and must have been a couple of years of shooting. Perfect light all the time.
I especially like the rising drone time-lapses and while the construction stuff is really really cool, I find it a bit distracting with all the crossfading. No other way to do it though I suppose.
All in all, probably the best time-lapse video out there.
I've been there shooting time-lapses myself but only 4 days... I would love to be able to spend a year catching all the best light and locations... Not good time-lapse scenery where I live.
