Day 4 of the December Challenge.
Rex is a wrestler, an aviator, a truck driver, an Indy Car racer, an artist, and many more things -- plus he's my son. He likes to show off his "muscles" when wearing his Blue Demon Lucha Libre mask (which actually came from Monterrey), so we played around with the wireless flash to throw some shadows.
You can also see this photo on my December Challenge blog entry.
I also used this photo in another article titled "16 Inspirational Portrait Photography Techniques" -- so check that out too.
