Topic: Lesson learned and what are you running?
The setup in the Miata is currently a de-batteried GoPro 9 powered by a cheap UPS. To correct the light balancing (so the camera doesn't reference the inside of car and bleach the view out the windshield) I have to manually set the meter each time I turn the camera on (I use a 1TB card so only have to go through this process once a day or once in a 24 race). When I'm feeling saucy I overlay GPS data from a SOLO2 DL.
This has been working fine enough but I found a flaw in my plan at this last true 24. Once we got the car running again at 4:30AM I started up the camera and set the light meter as per normal. When I went to edit the footage I found the post-sunrise video was completely whited-out. It looks like setting the light meter to a specific place in the frame (the windshield) also locked in the light meter level (in this case, it locked to a very dark scene). This is a bummer as I was hoping to have usable video of our wheel hitting the turn 5 bunker when it ripped off towards the end of the race.
My solution (assuming the sensor isn't jacked) will be to mount the camera to the dash bar (so I don't have to set the light meter at all) and run a second cheapo camera on the driver and cabin.
So there, that's my lesson learned in case it is helpful to anyone else.
Also - what camera setups are folks running this year? I'm always on the lookout for a better solution.
