Then this is the right video for you, because in this video you're gon na learn the most important thing that separates beginners from pros hi i'm paul from dronesgrid.com and in this video we're going to take a look at my dji mavic air 2 and how nd Filters work in general and specifically how to use drone filters to skyrocket, the production and the video quality of your drone footage i'm. Also going to make another video focusing more on how to take long. Exposure'S photo with drones, which is a bit tricky, but don't forget to subscribe for that, because i do have a secret tip for you, as i mentioned in the beginning, i do have the dji mavic 2 here and i simply love it, but before we step into The specifics let's go over how nd filters actually work and why they're so important for drones in particular. Nd filters basically mean neutral density filter and is nothing more than a high quality and fancy pair of sunglasses for your camera or drone camera. In this case, there's. More to it, but the main aspect we're looking to cover is movement. Movement and blurriness has a really strong appeal when it comes to how cinematic something feels. The advantage of a neutral density filter is that it reduces the amount of light getting through the sensor of your camera. It has a variable opacity depending on the filter. To put it simply, the nd filter may be more or less black, depending on your choice, which determines how useful it is.
This relates to what videographers call the 180 rule, which basically means you should keep a constant ratio between shutter speed and frame rate, and the ratio is 2 to 1.. So if you record in 30 fps, you should have a shutter speed of 1 by 60 and if you record in 60 fps, your shutter speed should be won by 120 and so on. The most noticeable difference is when the camera you're filming with is moving or there are some moving subjects, and this is the most apparent in daylight since the minimum iso is 100 on most cameras, including the mavic air 2. The camera will try to automatically increase the shutter speed to compensate for the strong light outside and frames will look very sharp and jittery, not cinematic at all. As you can see right here and if you're using a drone, this is even more apparent as there's. More movement involved. Usually, however, if you have this pair of sunglasses for your drone, you'll get to choose one. So the aperture is double the shutter speed and you'll get results like these. As you can see, the image is blurred proportionally and is easier on the eyes. Everything is creamier and looks more cinematic just by following this rule, Music, Music, now it's a bit of a pain to choose which nd filter you have for which situation as they come with different intensity levels. But some great advice i can give you for drones, especially is the following: do not raise your drone and fly to test the nd filters simply test the filters on the ground and point the drone camera in a direction with similar lighting to what you would capture From above it's preferable to choose a strong nd filter and raise the iso afterwards, rather than a weaker one and having to Music change Music, oh Music, bye boom be Music.
Oh now, let's take a closer look at the filters i have here. You can find them linked in the description. There is a 4 an 8 16 32 and 64. and the higher the number the more opacity the filter has. In this case you can see there is a difference between the red circular ones and the standard black ones. The red filters also come with an adjustable polarizing lens. Its main purpose is to reduce reflections from glass and water and keep the cinematic effect without drawing attention to an unwanted portion of the shot it's very important, especially if you want to record or take pictures of water and glass, all in all, a good acquisition. If you want to be a professional, the standard, dji filters, won't come with polarization. Unfortunately, depending on time of the day, you might find that you'll need to use up to three filter densities and adjust correspondingly nd. Filters are also used in photography a lot to get those long exposure shots with waterfalls that look magnificent as if they're filled with gas or something i'll do a more in depth. Article and video soon about that. As a conclusion, you will want a good set of nd filters because they're simply in front of your camera and you don't want any imperfections or distortions or impurities there and most of all, you want to keep them clean and don't put any fingerprints on them. If you want to find more details about how to use nd filters and basically anything else regarding drone videography and photography, there's a link in the description to an excellent course that i recommend it will also teach you in detail how to make money with drones.
So i'm pretty sure it's worth it since i've done it myself, oh and you're getting 100 off with that link.
