The DJI Drones are capable of making some great photographs and videos, I have been amazed by the the quality of image I can get from the Mavic Air from such a small sensor. But there are limitations. My Mavic Air is fixed aperture, which means it limits some of this (another reason to buy the Mavic Pro 2!).
I agree with Dave that keeping it in automatic while you are starting to learn is a good idea as you will have more chance of success. Also only worry about shooting JPG. RAW needs additional editing skills to get the best and that takes more time to learn, and shooting jpg only give you lots of space on the memory card.
But as Jeff suggests, also start to look at others as well. Start to learn what they are doing and then try some of the ideas yourself, learning what adjusting settings can make to your pictures. Basically, you can beat lots of practice. For me, the a key thing to be aware of is what difference the location of the sun can make on the image.
If you are new to photography but have access to a digital camera, practice on that so you can try things out without worrying about flying at the same time.
