Default Strapping a Tri-pod into a Cardinal...

Well I rather like the method used in the article supplied by Kev...
the only thing I wonder is if the tripod is going to be affected by
pitch and bank, I guess the two bungee cords will hold it against
lateral and probably verticle acceleration, but I want to be sure it's
going to be okay when the plane is banking about 20 degrees.

Also, I don't want to use the spnge method because I don't want the
standard "over the dash" shot that you see in many cars and planes, I
want to use my 0.5X lens and get the shot from just above eye level
from the back seat, so you can see the instrument panel and out the
plane and me and any pax/other pilot sitting up front, a better angle I
think.


One problem:

The contrast ratio is just too much for a video camera to handle (or even a
film camera for that matter...) so you won't be able to properly expose both
the view outside and your panel without some creative filtration. One
alternative (rather than totally covering your windscreen with ND) is to get
a split ND (Neutral Density) filter and align it with the line formed by
your glareshield. About 4 stops worth ought to be a good starting point.

Without the ND, you'll have either a properly exposed panel and blown out
views outside or a pristine outside view with a black hole where the panel
should be.

Good luck with your project.

PS...One suggestion for securing the tripod: See if you can find a way to
exert a strong downward pull. You'll notice serious nature photographers
get this by hanging their camera bags or sandbags on hooks at the bottom of
the center column of their tripods. Chain it or MilSpec bungee cord it to
the floor of your cabin if you can.
