Hero Post-Up/Down

During my Up/Down shoot I had visioned using the swing set however they weren't as interesting as I thought they would be. I ended up using the fireman's pole and the spinning ride. For both of these shots I laid on my back getting the shot from underneath my subject. The spinning ride was the most difficult, I had my shutter speed at 1/20 second and was trying hard not to move so I wouldn't get the subject blurry but still getting the background blurry. I had him run around with the contraption and then jump on, quickly getting the shot before he fell. They sky was in my favor, it was not too sunny to where I wouldn't be able to get the shot I wanted. In the end I couldn't decide which image I wanted to use for my hero post so I decided to use both.
