Research the area beforehand. You need to know what aerial shots or landmarks to include. For example, how close a house is to the beach or some water. Or near a popular area downtown.
Ask your client if they want anything specific to be included such as golf courses, parks or anything else. On the flip side, ask them if there’s anything that they want left out. They probably don’t want industrial structures or cell towers to stand out.
Choosing the proper time to do the shoot is massively important. You need the sun to light up the home, but not to an extreme level. It’s going to be different for different areas and landscapes. A beachfront property is going to need to be shot a different time than a property near a bunch of trees.
You should want 10 seconds or so of smooth video at a time. Higher frame rates will allow you to slow shots down even more without losing the smoothness of the video. Plan out the best routes around what you want as well, to make sure you get the best out of your battery.
