Colorado River in Glenwood Canyon

I was rather busy paddling my Thunderbolt kayak during the recent Colorado River Race in Glenwood Canyon. Nevertheless, I shot 180 pictures with Pentax Optio W10 camera and, now, you can follow the 10 mile race in just 60 seconds.

1. The camera was mounted on a deck of the Thunderbolt kayak. I used a camera mount based on three suction cups from the Sticky Pod together with a short extension and two knuckles.

2. The camera was set in an interval mode: a picture every 30 seconds up to 180 pictures. I did not have time to test this setup before the race. I started a frame sequence a minute or two before the start. I paddled 10 miles in 1 hour and 8 minutes, so I had several shots left when cooling down at the finish and carrying the kayak to the shore.

3. The frames were assembled into a video clip without any adjustments. I only removed some repeating frames from the finish. Most pictures came OK, only a couple were blurry, a few were affected by direct sun despite that fact that the race was in the morning and we paddled west. I need to use something to protect lens against the sun.

4. I was getting a lot of splashes in rapids. You can see some water drops after the first rapid, but, generally, I didn't have problems with water on the lens. The camera was shifted a little bit in high standing waves of the second rapid.

5. The river looks pretty empty in my animation. However, I run five rapids and passed 7 boats. There was a staggered start with slower canoes going first and the three fast kayaks starting as last ones.

6. I should shoot pictures every 10 seconds instead of 30s. 10 seconds is the lower limit in the interval model. My speed during the race was close to 9 mph, so, in average, I traveled about 360 feet between shots. I am sure that my speed was much higher in all river drops where the action was more interesting. I had enough memory - I can store about 800 full resolution pictures (2816x2112) in 2 Gb memory card. On the other hand, I could store only about 30 minutes of video, not enough to cover the race.

7. You can compare my animated video clip to the short movie I shot in Glenwood Canyon in September of 2006 around the second rapid. The animated sequence of frames provides a good overview of the entire 10 mile race course. Of course, the higher sampling frequency would allow us to better see the rapids.
