Product Information

So why do you need ND filters on a GoPro camera? There are a few situations where a good ND filter will have a huge impact on your videos or images. For the best results, keep your ISO settings as low as possible to minimize noise and maintain image quality. There are a couple of real-world uses for the ND filter—one involving aperture and one involving shutter speed. 1. Aperture — Shallow depth of field in brightly lit environments

Keep in mind that too much motion blur isn’t always a good idea, as it can make your video appear out of focus. That’s why it’s crucial to know the optimal amount of motion blur needed. It’s best to follow the 180-degree rule, which I will explain below. The 180-Degree Rule FPS (frames per second) is the frame rate, it can significantly influences your video’s look and feel. If you’re not using an ND filter, you can just set the Shutter Speed to Auto, the camera will handle it for you to get an ideal exposure. You may set Shutter Speed to a fixed value which will give you a more consistent look, but you should use ND filters to get a correctly exposed image. This post explains in more detail why you should use ND filter and how to select the correct ND.

Filter Shapes

ND filters come in various strengths: ND2, ND4, ND8, ND16, ND32, ND64, or even higher. The strength number indicates the amount of light reduction, with a larger number signifying greater reduction.

There is a useful term in videography and cinematography known as shutter angle.

ISO is the digital enhancement of light sensitivity in your camera’s image sensor. It helps adjust the exposure of the image by amplifying the signal. A higher ISO increases light sensitivity, which improves visibility in low-light environments, but it also introduces and amplifies digital noise, resulting in a grainier image. When using a fixed shutter speed, be sure to equip your GoPro with the appropriate ND filter for proper exposure. I recommend an ND16 filter for sunny days, ND8 for cloudy days, ND4 for early mornings and sunsets, and ND32 for snowy days. For reference, on a bright day, ND16 or ND32 filters give good results with GoPro cameras, however, this will vary depending on the frame rate and shutter angle selected.

Auto white balance can work effectively most of the time, but experienced users usually set it manually to match the scene, because there might be instances where the Auto settings is just off which compromises the overall look of your footage. Setting it to a fixed value ensures consistent white balance, and allows you to fine tune it later in post-production. For example, you may use 4500K when shooting on a sunny day or 5500K on a cloudy day. If you’re unfamiliar with adjusting white balance in post, feel free to just set it to auto and let the camera to handle it for you and save yourself some headache. The native aspect ratio for the latest GoPro image sensor is 8:7, while older models have a 4:3 sensor. Choosing the native aspect ratio makes use of the full sensor information, whereas using a non-native ratio results in cropping at the top and bottom of the sensor. When using Hyperview and Superview, the image is dynamically stretched from 8:7 or 4:3 to 16:9.

I use friction-fit ND filters on a GoPro on my FPV drones as well as on my helmet for mountain biking and motorcycling. I am yet to lose a friction ND filter in any of those scenarios. Here is an example: from left to right, the shutter speed is progressively lowered while using a higher ND filter to maintain the same exposure level. There’s more motion blur on the right. Get your ND filters for the GoPro here. A set of ND32, ND16 and ND8 will get you pretty much all covered:Your choice of ND filter depends heavily on the environment and lighting conditions. Here are my personal recommendations:

The 180-degree shutter rule works best with stabilized, such as predictable camera movements on a slider or gimbal. However, for dynamic, shaky situations like FPV drone or action-camera shots, it can lead to excessive blur. Instead, faster shutter speeds (90° or even 45° rule) might work better, reducing motion blur and facilitating better post-stabilization results, because footage that’s too blurry might not work well in digital image stablization. With 90° rule, set shutter speed to 1/120 for 30fps, or set it to 1/240 for 60fps (one over four times the fps). With 45° rule, set shutter speed to 1/240 for 30fps, or set it to 1/480 for 60fps (one over 8 times the fps). White balance determines the color temperature of your footage, it’s crucial for capturing accurate colors. You can leave your camera in auto mode with very good results. Just put an ND filter (ND4 or ND8 works great for cloudy or overcast days, or an ND16 if it is a sunny day) on your camera, and leave it. You would only need to remove it if you are filming video in low light (e.g. sunset) or dark conditions. This will smooth out your video and reduce jello.

Stacking Filters

Following this rule should provide an appropriate amount of motion blur. If you desire even more motion blur, you can try a shutter angle of 360 degrees (the maximum limit), which means setting the shutter speed equal to the inverse of the frame rate. For example, at 30 fps, set the shutter speed to 1/30. However, some people may consider this to be “too much motion blur.” You can also experiment with shutter angles between 180 and 360 degrees, but most individuals will likely be satisfied with the 180-degree rule. ND filters come in different strengths or darkness levels. For the photographer, the easiest thing would be to have ND filters that tell you how many stops of light they will darken your exposure. Designed by optical engineers, most brands of ND filters label their products with either an ND filter factor number or optical density number. Unfortunately, for the photographer, neither the filter factor nor the optical density number are equal to the number of stops by which the light is reduced. The foremost lens of these GoPro cameras can twist off and on. These are known as twist-on ND filters. For example, GoPro sells Polar Pro ND filters with this twist-on mounting system. The general rule of thumb is to set the shutter speed to 1/60 for 30fps, 1/120 for 60fps, 1/240 for 120fps, or 1/480 for 240fps. Using a lower shutter speed than the suggested value may result in overexposure and excessive motion blur.
