Ok, I was just watching a documentary series about masters of photography, and there was Jacques-Henri Lartigue showing his albums when he turned the page and I saw this.
Very interesting image: there's skew in both directions because there was movement in both directions and it was shot definitely on film.:)
So it'd be interesting if anyone with more experience explained what type of camera/shutter/technique caused this artifact.
It also serves as an example for those who think that rolling shutter skew can be easily removed in post, and for those who think it will only happen in Bourne/Cloverfield/shakycam style shots... and prove them both wrong.
I could also be argued that this could be use as a tool to build an interesting stylized image... those bent-forward tyres look cartoony. :clown2:
Excuse my English, if it doesn't seem clear.
