Cool link ... Why plane propellers look weird in photos

[kenny]

Amazingly, all of the blades you see in this pic are of the same propeller, not blades of another propeller next to it.



This link has a GIF that's brilliantly explains this phenomenon.
It's another example of something I keep preaching here on PS, 'you can't always believe pictures'.

I love this kind of thing.
