The DJI Action 3 camera already takes really good pictures by default, but using ND filters makes the pictures even more intense. The set was delivered in a practical box, ideal for storage on the go.

A CPL filter is used when pictures are to be taken despite strong sunlight and reflections from water or windows. This prevents details from being lost due to overexposure. A polarizing filter (or polarizing filter for short) is a polarizer for light. Polarizing filters are known to be a "must have" for every photographer.

The filters CPL + ND) are only screwed, like the original, so a quick change is possible. The CPL filter is my favorite for photos and videos, whether with my drones, my DJI Pocket2 and now also with the Action 3. Because it gives the colors more contrast and minimizes reflections considerably. The ND8 and ND16 are often used for the ND filters. The ND32 when it's extremely bright, in winter when it's snowing, on days with clear skies and clear sunshine. The ND 64 softens the fast movements in waterfalls and clouds, which comes across really well. Because everything else is razor sharp. Try it yourself and compare the results.

The quality of the materials is impeccable and the processing of the filters is perfect. The attachment is easy, they hold reliably, fit exactly like the original. The filters are also tight underwater, which I tested yesterday in a body of water with a stick extension.

Explanation of the ND filter: I use them for long-term exposure and depending on the sunlight. This allows you to take softer shots. For example, gently blurring waterfalls and clouds.

What is a neutral density filter/ND filter? A neutral density filter is a filter where the glass is completely darkened so that less light can enter the lens.
So it is possible to choose longer shutter speeds and to achieve the corresponding effects, such as foggy water or soft, long-drawn-out clouds. This would not be possible without a filter, as the image would be extremely overexposed or even completely white.

I am very satisfied with this filter set and can recommend it unreservedly.

Thank you for taking the time to read my review. I hope that I could be of some help.
