Kobe

1. The photo to the left he's in a game and is showing the basketball player he is. The dedication he puts into trying to win the game and score the points needed. The right photo he's in a tuxedo at an event most likely. His basketball career and skills have brought him his fame and fortune. I think this photo shows that.

2. The techniques used for the game image is basically the pose he's in. Most professional athletes when their photo taken during a game the pose they're in shows the most about them. Like for this one it shows Kobe with total control of the ball at hand, positioned nicely, and getting ready to lay it in. The photo with him nicely dressed focuses on his appearance and facial expressions made. These photos I would guess are taken based on the person's actions or expressions showed, also possibly depending on the location or event.
