I recently went for a helicopter ride and found many images were ruined by reflections from inside the cab.
I was asked to go again last week. I though best get a polarising filter to try and cut those reflections out, and also to help with cutting through the haze over the mountains we were to shoot.
But while I was up there shooting today I noticed an issue with using it.
As you dialed it in to cut the haze down and get the saturation up on the scene outside, the reflections inside got worse ... as I dialed to take the reflections away the scene outside became washed out ...
I vaguely now remembering reading something about this, perhaps about how using 2 filters cancel each other out, like there is a odd even odd even odd even, sort of back and forth in the wave length or what is going on there.
Of course the solution would be to take the doors off, but he wont do that .... so I have low saturated shots with no, or little reflection and high sat shots with more reflection.
I'll be going up again to try get these shots, but maybe now not till our Autumn, winter when the sky is clear in the afternoons, as we need the afternoon sun on these cliff faces ....
Anyway, it would be nice to hear a little more about this Polarising effect and have it worked out for my next trip.
It is about getting the chopper at the right angle etc etc also ....
So please discuss !
