Darn Nosale, that's what I call a very helpful answer, thanks a bunch.
Noted on the app for the filters and now I'm getting a bit clearer, as I suffer a lot from the haze living in Hong Kong I'm going to try the PL/ND first.
I suggest you google on the subject of using polarizing filters. There are numerous good articles that explain the principle, the benefits and the potential misuse of polarization. I'm still early in the learning curve.
In short, polarization eliminates light entering the lens from a source at a 90 angle. In still photography, every time the photographer aims his lens in a different direction, there is usually a counteraction to rotate the polarizing lens on the camera to accommodate the angle that polarized light is filtered out. There is also a good video on the PolarPro website that illustrates how to rotate their PL/ND filters to set the right polarization. The caveat is that once this has been done on a drone lens, it is set for that specific lighting. Once you start turning your drone into different directions, there is a high chance the polarization effect will no longer be optimal. But it will still likely be beneficial to some extent.
It seems to capture a good shot with the best polarization effect, you determine the general direction you will be shooting video/stills, set the polarization, then fly that pre-planned direction. If you are going to be navigating in differing/opposing directions, then some of that time the polarizing filter will not be achieving maximum benefit.
On the other hand, ND filters with no polarization are not impacted nearly the same when pointing the camera in different direction. However, should overall lighting change dramatically, then you could find yourself flying with a less than optimal ND filter.
You always have the ability to adjust the EV to counteract the effect of changing light when flying with an ND filter. I don't think changing the EV will be very useful for changes to polarized lighting.
I still have a lot to learn and am sure there are other more experienced in photography that can weigh in. The bottom line is that there is likely no perfect solution using PL/ND, but with trial and error, I think more can be learned that will benefit most images.
Just remember, in some cases where PL serves no purpose (reducing glare/haze, pulling in more saturated color), you might be better to use the ND filters for the relevant light conditions...... |
