Quite often drone footage is shot from high altitudes. When the subject is far away and there are no moving elements, the difference in motion blur is hardly noticeable, so in this case, ND filters are not strictly needed For hyperlapses and photos we use ND filters with values ranging from ND 64 to ND 1000, according to the light conditions. In the case of the DJI Mini 3 Pro on certain occasion, a ND2000 is useful, although not mandatory, due to the very wide aperture of the lens Which ND filters should I buy for the DJI Mini 3 Pro? The primary purpose of neutral density filters is to reduce shutter speeds even when filming in brightly-lit environments. ND filters are like sunglasses for your drone and can be polarized or non-polarized. In this case, we should use an ND128 filter to be able to use a shutter speed of 1/50 of a second Which ND filter is most useful for video? Weight: The filter weighs 1.5g and replaces the camera's lens protector, which weighs 0.7g. The drone therefore weighs 0.8 g more with the filter and therefore remains safely in the range of under 250 g total weight and can continue to be used without a drone license.

Long-exposure drone photography is also gaining in popularity. Capturing long-exposure photos on bright days would need a lot more filtering, for example, using an ND256 or higher filter. Third-party ND filters For example, in the UK, the weather can be bright sunshine one minute and heavily overcast the next. Usually, portraits require a complete focus on the subject. So, using the ND filters for the DJI Mini 3 Pro allows you to regulate the depth of field in extreme light conditions.So, the wide aperture helps you achieve a shallow depth of field from sharper shots. Subsequently, the reduced shutter speed blurs any unnecessary movement in your photo. Most importantly, the ND filters reduce the intensity of light entering the camera. This way, you can easily control the shutter speed and aperture. For photography with the Mini 3 Pro and with drones in general, ND filters are not a must. For someone really serious about photography, ND filters are a desirable item, but not a necessity ND or neutral density filters are filters that can be positioned over the lens of a camera to reduce the amount of light hitting the sensor for a given period.

For example, under this rule for natural motion blur at 24 frames per second, the shutter speed would be 1/48 seconds. DJI’s own filter set and any spares will likely be around for as long as that drone model is still actively supported. For example, using aftermarket propellers on a DJI Mini in the UK can deem it a privately-built drone as it is no longer built to manufacturer specifications. Whether DJI would honor any warranty claims when using third-party filters is unclear, especially when they offer their own set of ND filters.ND filters are the best-selling accessory for drones, but many users don’t know much about them and often ask if they should buy them and why For instance, to increase motion blur, you can slow the shutter speed and increase light filtering by using a higher-value ND filter. Based on previous experience with third-party ND filters, ND filters from the likes of Neewer and Freewell for the Mini 3 could be a good option. As mentioned, they offer various ND filter sets, which are around the same price as DJI’s own filter set. DJI offers a darker ND256 filter because of the larger pixel size on the Mini 3 when compared to something like the Mini 2. As an example, with the Mini 3 Pro on a bright day, using the minimum ISO value of 100, we obtain a shutter speed of about 1/8000 for correct exposure. Assuming that we want to use a SS of approximately 1/50 for the correct amount of motion blur. Let’s see which strength value we need

Glass ND filters are also advisable because they protect your lens better and are easier to clean. They are also less likely to impact the color of the light being filtered than plastic filters, as claimed. Other factors to consider

Still, if I want to keep objects in a frame looking sharp, then a shutter angle of 90 degrees can reduce motion blur, especially as the aperture of most camera drones is reasonably open and fixed, including the Mini 3. White balance: I did not notice any significant differences in the white balance value between the individual ND levels. The color chart was photographed in each case by Datacolor. The generally accepted rule for natural motion blur is to maintain a 180-degree shutter angle, which equates to the shutter speed being twice the value of the frame rate. Once you’ve decided on your frame rate and shutter angle, you’ll then want to choose an ND filter that gives you optimum exposure for those parameters. Knowing which to choose for particular conditions comes with experience. How to mount ND filters to the Mini 3 At present, there doesn’t seem to be much difference in cost between third-party and OEM ND filters, at least in the US.Cost may be a bigger factor depending on where you are.
