It’s all about the Golden Hours. Often you may not have a choice when you are going to film something, just because shoots are usually set up far in advance and have many unpredictable factors involved. However, if you do have a choice, by now, the best hours for cinematic drone imagery are the Golden Hours of the day at Sunrise and Sunset. The long shadows during the golden hour will help define terrains’ features.
It should also be noted that fewer people typically film at these times, so just by doing this one essential step, you are already helping to differentiate your drone footage.
