Why and how do you use ND filters for video, and what exactly do polarizing filters do? In this video, I'll show you which neutral density filter you should use for your videos and when. ▶ Free training: http://hochzeitsvideopro.com ▶ Polar Pro Variable ND Filter Peter McKinnon (2-5 stops): https://amzn.to/3U01riw ▶ Polar Pro ND16/POL Filter: https://amzn.to/2Zzaz1Q ▶ My equipment and recommendations: https://kit.co/walterweber 00:00 Intro 00:28 Shutter speed rule 02:02 When to use neutral density filters 02:42 Camera settings 03:33 Polar Pro ND filters 04:38 Cheap neutral density filters 05:25 How to use polarizing filters correctly 06:43 Thread size 07:44 Outro Let's first talk about ND filters for video. ND filters or gray filters are like sunglasses for your camera and help darken the image. But why exactly should you use ND filters? 1. 180° Shutter Rule / Motion Blur 2. Depth of Field The 180° shutter rule states that you should set your exposure time so that it's twice your frame rate. At 24 FPS, that would be 1/48, and since this is often not possible with DSLR or DSLM cameras, the closest you can get is 1/50. This has the effect of creating natural motion blur, which gives the image a cinematic look, in contrast to filming with an exposure time of 1/1000. Now let's get to the problem: A scenario you often encounter, especially when filming on vacation: You're outside and the sun is shining. If you want to set a very wide aperture here—let's say 2.8—and at the same time adhere to the 180° rule, for example, because you're filming at 24 FPS and setting the exposure time to 1/50, your image will be very overexposed, even if your ISO is set to 100. To compensate for this, use an ND filter. This allows you to keep the same settings but darken the image correctly. Of course, you can also solve the problem differently, by simply closing your aperture and going to f/8, for example. While you'll still adhere to the 180° rule, you'll lose the beautiful depth of field. Therefore, the solution is to use an ND filter. So, which ND filter should you use? This depends on two main factors: 1. Time of day & light intensity 2. Camera settings Let's talk about the time of day: When the sun is shining outside, it's brighter than when it's cloudy. Therefore, you have different light intensities and need a different ND filter strength each time. You also have a different light intensity when the sun is about to set or has already set. If you're filming inside a building, it's usually dark enough that you don't need an ND filter, but there are certainly exceptions here too. 2. Camera settings: As just discussed, you should try to follow the 180° rule. So, if you're filming at 24 FPS, your exposure time should be 1/50. However, if you're filming at 60 FPS, your exposure time should be 1/120 or 1/125. Therefore, the shorter your exposure time, the weaker your ND filter should be. Your chosen aperture is also crucial. An aperture of f/1.8 lets significantly more light into your lens than an aperture of f/4. The more light you let into the sensor, the stronger your ND filter should be. A variable ND filter is very useful for precisely these situations. This filter offers different strengths for different situations. Really good ND filters that I can recommend are those from PolarPro, and the Variable ND Filter with 2-5 stops makes the most sense, as it covers ND 8, ND 16, and almost up to ND 64. You can cover exactly these strengths quite well if you use a shutter speed of 1/50 and a maximum aperture of f/2.8. This allows you to cover all situations, whether it's sunny, cloudy, or a sunset. Now let's talk about polarizing filters: A polarizing filter helps you block the sun's reflections. This makes colors more saturated, highlights are reduced, and overall the image looks as if it has more dynamic range. To set the polarizing filter correctly, proceed as follows: Turn yourself or your camera towards the sun. Then turn exactly 180° and continue looking up at the sky. From here, adjust the polarizing filter and try to find the sweet spot. The ND filter strength I use most often for videos is ND16. Personally, I usually film at 60 FPS and thus have an exposure time of 1/125.
