Over the weekend I participated in a track day at Taupo. We used the short track three.
As an experiment, I taped the iPhone to the headrest of the passenger seat.
When home and on the laptop I viewed it and was disappointed with it. The picture is sideways due to the position of the phone while recording and the vibrations have distorted the picture. The only saving grace is the sound. Under experimental conditions, I was running an open plenum on the stock ecu controlled silver top.
Unfortunately I'm a perfectionist. Because the picture quality is poor I haven't posted it up here. However if enough people wish to "hear it" comment now .
It also gives me some time as the Internet at home is down until Friday. Also more than enough time for some good debate over "film quality standard"
