VAskier, I'd slightly alter your statement. The super-wide angle (almost fisheye) lense of the gopro is warping the photo to exaggerate the bending to a certain degree. If you look at
https://wiki.panotools.org/Fisheye_Projection you can see the general idea of how a fisheye projection bends straight lines. In this case, given the location and direction of the ski, there actually isn't too much exaggeration. The photo is not likely to be exaggerating the amount of tipping, however. So that is what we should really be looking at!
And dougtee, you should know better than saying "bend the ski" on these forums.
If the skier in question is a good skier, they tipped the ski and the bending just happened!
It's a pretty fun picture, regardless!
