Should I use a CPL filter on my drone?
I shoot a lot of aerial photography near lakes and coastlines. Someone told me a CPL filter would help with reflections but I am not sure if it works the same way as on a regular camera. Is it worth buying one for my drone?

Yes, a CPL filter is one of the most useful drone accessories for photography near water, glass buildings, or anything with strong reflections. It works by blocking polarized light, which cuts glare and boosts color saturation in ways that cannot be replicated in post-processing.
The key benefit: when shooting lakes, rivers, or the ocean from above, a CPL can make the water look deep and rich rather than washed out. Skies also get a noticeably deeper blue, and foliage becomes more vivid. For real estate photography with pools or windows, it is almost essential.
The main trade-off is light loss. A CPL typically reduces incoming light by 1.5 to 2 stops, so you need bright conditions. On overcast days or at dusk, skip it. Also note that the polarizing effect changes depending on the angle of your drone relative to the sun, so results vary throughout the day.
Make sure you buy a CPL made specifically for your drone model since the thread size matters. Generic filters often do not fit well and can cause vignetting.

I use a CPL almost every time I shoot video near water. The difference in footage quality is dramatic. Without it, a bright lake looks like a mirror and you cannot see into the water at all. With a CPL, you get depth, color, and clarity. Just remember to rotate the filter slowly until you get the maximum polarization effect before recording.

For real estate work I always carry a CPL. Shooting properties with pools or large windows, the glare reduction makes a huge difference. Clients notice it even if they do not know what caused it. I pair it with an ND filter set so I have both covered depending on the scene. The CPL alone does not replace ND filters for video work though.

One thing people miss is that a CPL is less effective when the sun is directly behind you or directly in front of you. It works best when the sun is at roughly 90 degrees to your lens. So plan your shots accordingly. Also, some CPL filters designed for small drones use fixed polarization instead of rotating, which limits how much you can dial in the effect.

If you mostly shoot in overcast conditions or at golden hour, a CPL might not be worth the light penalty. For bright midday coastal shots though, it is absolutely worth it. I bought a budget CPL set and even those made a visible improvement for my beach footage. Start with an affordable set before investing in premium glass.
