clouds going away, shadows coming toward me?Can you see the issue here?
Here is what's going on with this video. Yes, the issue is that the clouds are going one way, and the shadows (or sunlit areas) in the opposite direction. But the intention of the video was to test the observer on their visual logic. What the video is showing and what I implied by the title was a parallax event, supposedly a rare occurrence. The fact is, it is impossible. The sun is too far away to create such a parallax. What I wanted from the observer was for them to say... "Hey, wait a minute! That's not possible. You faked it!" But when you casually look at the video, it looks somewhat logical. I had a lot of people on Facebook look at the video and say "Cool, Looks beautiful, Nice shot", etc. But nobody told me that it is not possible and not real. So I posted it here to see what would happen. @Made2Phly was the first person after 50 views to PM me and say "wait a minute!"
I've done a similar solicitation of reaction with other videos I've created with my MPP. One in particular "House of Gardens", included shots showing the movement of the sun over a period of hours. No drone can fly that long, and I wanted to see if someone would catch it. No one did. The fact is, the drone was not flying but staged on a high platform. In my book, that's cheating and I wanted someone to call me on it.
The creation of Cloud Parallax started with a simple time-lapse. With a tripodded field of view (drone not moving), it is easy to apply shape masks to selectively color correct the sky separate from the ground. I then stacked the shot and separately trimmed the sky and the ground clips to meet at the horizon. Then I reversed the sky clip. It looks natural, but then when you think about it, it's not natural.
Thanks for watching!
True, but it would take hours to observe the effect simulated in my video, requiring an earth bound tripod mounted camera, not a 20 minute drone flight. Like you say, unlikely.It's not that the sun is too far away, because its relative motion is determined by the earth's rotation. That effect is actually possible, but only if the clouds are moving across the sky slower than the sun, and in the same direction - a rather unlikely event.
