If a few skiers make a photo to demonstate perfect form, they will likely co-ordinate the effort of skier and photographer to produce that perfect turn.
Also, if skiers make a photo to show a skier handling very difficult terrain well, steep and narrow for example, the photo will likely show a perfect turn because that is the only type of turn that will be solid and safe for that moment in that place in those conditions.
Lastly, if skiers make a photo of skiin' around, havin' fun, letting it rock and roll any way it feels good on easy to moderate terrain, then the photo may show a turn that has technical flaws which in the moment shown were a lot of fun, like rotation, banking, launching an airborne pivot, laying back and wheely-ing, whatever strikes ones fancy and makes you smile.
While one has to know how to make a solid, strong, (perfect?) turn for when the situation demands it, there are many fun turns to make when the situation allows it. IMO.
(the skier shown is enjoying himself, completely relaxed on moderate terrain, not modeling for technical review or shredding the gnar, I'd say)
