I think the subject of photography and videography is far deeper than some/many may imagine. There is no easy way to learn it all at once. Typically when people start throwing out suggestions, as helpful as they may be; they can be confusing and cause more questions than they answer. I believe I could have gotten 2 or 3 four year degrees in the same time I have spent chasing imagery production and I am still learning.
Having said that, if you're new to photography and even drone photography here is the good news, cameras are getting much better all the time and the truth is you don't
need* to know as much as it took years ago. Start with the basics, let your camera run on auto settings in the beginning because believe it or not, the settings on auto will be about 75 to 80% of the way there and to get further you need to know exactly what to do and when for any given circumstance
* You may not
need to know to start but to progress and get better you will at some point have to learn the basics.
Drone Tip#1: Always establish a subject. If your photographing from a drone make sure there
is a subject and apply the rules. This can be difficult sometimes because we are moving and looking at many things. Video from a drone gets tougher for the same reason but always ask yourself - "What am I trying to show"? This will allow you better approach the task of getting the best picture.
Most of the improvements to one's photography comes from understanding the basics: Composition, rule of thirds, leading lines, framing the shot and so much more. To get started here is a great video showing the basics and how the interact with your photos. Now some of this is about portraiture and so fourth but these are the foundational rules.
