Actually, indirectly, you can, by observing several photons captured at different time slices during their courses.

Here what you are seeing is the group velocity of a wave front of many photons. The opposite effect might be shining a laser pointer at the moon and noticing that the dot moves across the moon's surface faster than the speed of light. No actual photon is ever observed going any speed other than C.
That femtosecond camera is freggin awesome though.
