The benefit of ND Filter for Videography

Today's videography is in great demand because of the availability of income fields such as YouTube and other social media. To support good video results, various tools are needed. For vloggers, a camera with a flip screen model may be needed. Gamers, maybe they need HDMI Capture and a green screen. 

Here, I who usually shoot videos while traveling at least need a lens filter. And what I discuss in this post is the ND (Neutral Density) filter. The way the ND filter works is to reduce the light entering the camera lens. Suppose we want to shoot a photo with slow shutter speed, the camera will capture a lot of light so that it becomes an overexposure or too bright photo. Well ... this is where an ND filter comes in. So that a long exposure photo will be created as below.

ND filter consists of several levels starting from ND4, ND8, ND16, etc. The higher the level, the more filtered light is so that less light enters the lens. But there is another type that covers these levels, namely the variable ND filter. The variable ND filter feature is that it can be set the ND level so it is more practical. However, the disadvantage of a variable ND filter is that there are sometimes uneven parts, for example, a photo that looks vignette. However, a variable ND filter is still a pleasure to use. The ND filter that I use is the Fotga Variable ND Filter.

In the market, the filter I use is around $ 10. This price is included in the entry-level category because on it there is still an ND filter which is expensive and of better quality. Actually, the reason I bought this ND filter was for photography needs. However, because lately, I am more dominant in videography, I try to use it in videography. After using it, it turns out that ND filters are important for videography too. Among others are. 

1. Motion blur effect on footage

On a bright day, a lot of light automatically enters the camera. So we need aperture, ISO, and shutter speed settings. If the aperture and ISO are set to a minimum, but the video is still too bright, then the last option is setting the shutter speed to a high speed. The difference can be seen below.

 

2. Bokeh in high light conditions

For videography, the shutter speed is often used in the 1/100 range. So to prevent overexposure when taking videos in bright light conditions is to reduce the aperture (f is bigger) and a low ISO. With this, the bokeh cannot be maximized. This is where an ND filter comes in.

At least that's what the ND filter functions for videography. Most of these filters are used in high light conditions.
