The woman is taller and is shooting straight-on, so the flash bulb lights the fingers head-on, as well as watches and stuff.
The boy is smaller and is shooting upwards, and the hand is high on the shoulder, so the flash bulb lights it from a low oblique angle. That's why things up high are darker in the second picture, because the boy is not lighting people head-on, but from a low angle.

? very nice attempt but
Sorry you wasted an excuse.
I am talking about the different colored watches on the agent in the background.
Actually the line of sight from photographer to subjects looks adult eye level in both of them. There is no evidence it is a smaller subject shooting “upward”, it is direct on at the same level.
