Nice shot, but shouldn't all feet be off the ground to qualify as a jump?

They don't just spring off all four feet. The back feet will lift off the ground as the pony goes over the jump - this particular part of the jump is called the 'height of the action' as the front legs tuck up and under, then as the forward momentum continues the back legs lift - hope that makes sense - I actually have the whole sequence photographed for this particular pony/jump but this one with the 'height of the action' is generally what sells.

Superb action shot..

nice
