There are (in my opinion) two things filters can do for you:
1. A polarizer can eliminate reflections from water etc. Making for a more pleasing look while filming / photographing reflective surfaces. Also it can produce very dark blue skies.
2. A ND filter can lower your overall shutterspeed by lowering the amount of light that hits the sensor. This is useful for video mostly.
There is sort of a rule of thumb that your shutterspeed 'should' match double your framerate.
So Spark shoots 30fps video, the shutterspeed should be 1/60.
That is said to deliver the best result.
Some talk about other effects like lowering contrast, reducing over exposure etc. etc.
Lowering contrast:
In my opinion that is NOT what ND filters do. You need a gradual ND filter, but that is useless on a drone as you have to manipulate the filter just before you take a picture so that it matches the horizon. This is obviously not possible or at least not convenient when the Spark is in the air.
Reducing over exposure:
I think ND filters are rarely needed for this.
At least, not when the amount of light is still not enough to hit the max shutterspeed.
If there is more light than the max shutterspeed can take, then an ND filter will help. But I doubt if you will often encounter that much light (I don't own a Spark, so I don't know if others have experienced this)
So yes, they are very handy if you want to achieve the best shutterspeed for video (ND) OR reduce reflections (Polarizer).
It's up to you if you need that. |
