A couple of years ago (when I was going through something of a ‘fine art’ phase) I played around with video art. The main concept I explored was the idea of capturing entirely still scenes that change slowly and subtly over the course of 10 to 20 minutes, giving the sense of a still photograph that looks slightly different every time you glance at it. Most of the results turned out to be incredibly boring and uneventful, but this one worked pretty well. The light was on my side and I managed to get my timing just right to capture the sky shifting from daytime to dusk.
I still find watching it quite therapeutic, and there are points where it looks almost beautiful (if I do say so myself). It is 15 minutes long, so if you decide to watch it and find yourself getting bored I’d suggest skipping to around 6 minutes in. That’s when it starts to look the most picturesque.
