4.1 Weather Factors
A drone is a tiny aircraft; it's subject to all the same forces that larger aircraft have to contend with. In this lesson you'll learn about suggested drone flying conditions and how to fly in different types of weather.

4.1 Weather Factors
In this lesson we are going to look at the different types of weather you may encounter when you are flying your drone and how this can affect your shots. We're also going to look at some suggested flying conditions and when you probably should not fly your drone. For the most part weather at a particular location is out of our control, aside from choosing a different day to shoot on. But in some cases this may not be possible with deadlines. So you'll need a good understanding of how different types of weather can effect your shots. Typically you're just gonna wanna fly on clear or cloudy days with little to no wind. On a clear day there will be numerous shadows cast down on the terrain and the time of day will play a factor in this. But, generally at midday the shadows will be at their smallest. On partially cloudy days, large shadows from different clouds will be cast down on the terrain. This can either help or hurt your short, depending on what you're looking for. I personally like these large shadows, cuz it gives the scene a good sense of depth and scale as it moves toward the horizon line. However, if you're getting shots of a location and part of the location is covered in large cloud shadows, this can be distracting and could even make the location look less flattering. It could also make it difficult to expose your drone camera properly, because of the darker areas and the shadows. On days if you completely overcast, your skyline's not gonna appear appealing, but overcast days act as a giant soft box for the sun's light. Scattering it more, which will actually give you the ability to capture some really saturated terrain shots without any harsh shadows at all. One of the drawbacks to this, though, is that the terrain can come off as looking very flat because there's a lot less contrast on the scene. Wind is also gonna be your biggest enemy when it comes to the dreaded Jello effect on your footage. If you can, avoid trying to get your shots on a windy day. I typically don't fly when the winds are over 20 mph, especially with heavy gusts. Most drones are rated to fly in up to 25 to 35 mile per hour winds. However, the footage probably won't even be worth your time. And if you fly a smaller drone such as the DGI Phantom 2 or 3, you'll really need to be mindful of the wind when you're capturing footage at high speeds. A basic rule is, the smaller the drone, the more sensitive it's gonna be to wind. Larger drones have a better time balancing and they won't be able to be pushed around quite as easily as a smaller drone. I also wouldn't recommend relying too heavily on programs like After Effects to remove the gel effect from your footage if you do end up using them. Although After Effects can do a pretty good job at removing these effects, I've never seen it remove the gel effects completely. Gel effects can be very distracting for viewer or clients, and it's a telltale sign that your footage was shot with a drone in sub par conditions. If you absolutely have to film on a windy day, keep your drone movements to a minimum. Honestly, I would not even move the drone at all, because your drone is gonna get bounced around by the wind even more while it's trying to move around. And if some shot movement is a must, only use your gimbal to rotate and not the actual drone. [MUSIC] And finally, on some days, you just gonna wanna avoid flying your drone altogether. Avoid flying when there's rain, misting, or real heavy fog. Particularly on colder days, since the condensation can develop on your drone and the props, which can freeze at higher altitudes. This can cause your drone have an unpredictable movement and be much less responsive. I myself, have actually witnessed the DGI Phantom 2 fly from the sky because of frozen condensation that developed on the props. You'll have to remember that a lot of wind is passing through the props of the drone and when this happens the props act like a filter capturing all the moisture on the prop blades. Even on warmer days when you fly your drone through heavy fog you're going to see moisture and condensation develop on the props and the drone. Recommended flying temperatures are between 15 and 100 degrees Fahrenheit, or -10 and 40 Celsius. And again, be very mindful of your drone when flying it at the ends of these spectrums. Often these extremes will have a direct effect on battery flight times. In the next lesson, we're gonna examine how flying at different times of the day can affect your footage.
