Aaron Sheldon's son, Harrison, reads a magazine inside a Columbus, Ohio, barbershop. He is wearing an astronaut costume for Sheldon's project "Small Steps Are Giant Leaps," which illustrates how children -- like astronauts -- are constantly exploring the world around them.
Sheldon wrote creative captions for each photo that compares his son's experiences to those of real-life astronauts. He called this one, taken at a luxury hotel, "weightless environment training." Sheldon said the hotel was Harrison's favorite place to shoot: "He keeps asking to go back there and take pictures."
Harrison takes public transportation. His dad said the project started soon after they rode the bus together. "I'm just sitting there looking at him," Sheldon said, "and he's in just in awe of such a mundane and pedestrian task."
They have taken photos at two dozen places around town. "It helps that every location that we've shot has been somewhat kid-friendly," Sheldon said. "I didn't just want this to be, 'OK, let's go out and take this photo.' It was, 'Let's go out and do something together.' "
Sheldon called this photo "Astronaut Picture Day."
This photo inside a movie theater was captioned by Sheldon as "Training Films."
