Camera angle is stupid indeed but those are damn high. Also, the first pic could be the same high, seeing the back of your hand is causing a deception, ive had that happen numerous times: check where that wrist bone is at the back of your hand, mark it, then turn your hand around, boom, it is 1-2'' below base of palm.
Anyway those both look like 2'' below base of palm, so 10'9'' - 10'10'' depending on hand size. ChrisM is right, gotta start trying to dunk, you are high enough now.
