Knowing your background would be very helpful but since we do not I will keep it as simple as possible, figuring you know little about filming and flying.
DO fly at different heights, approach angles and closeness (base closeness to your "subject" on your comfort level)
DO fly smooth and straight
DO fly slower (speed can be ramped up based on knowledge of flying as well the understanding that with speed comes additional complexities of piloting as well as possibilities of ruining a shot due to erratic movements of the craft and/or gimbal.
DO avoid flying ->into<- direct sunlight. This is not as critical with the inspire but avoid flying directly towards the sun unless you want your subjects on the ground to be darker. If you truly understand filming/photography you CAN fly into the sun for a desired look on your footage.
DO Try to fly as much as you can during the hour or so immediately after sunrise or an hour immediately before sunset (
Golden Hour)
DO try to fly around (and close) to other objects that will ultimately lead you to "revealing" your subjects. This extra motion in your shot even if it is not related to your subject will give extra dimension to your image and make it WAY more interesting!! I live in South Carolina and when I think of a ferry I think of boats that operate in/around rivers that have marshlands around them so try to envision that in this example... Fly close (10 - 15' above) the marshlands with the wispy grass/weeds coming up. Frame your shot to where the ferry is in the top half of the frame and the weeds are in the lower part. then fly over them towards the ferry. The extra motion of the weeds going by will add extreme dimension and interest to your shot!!! You could also angle your camera down and move it up (smoothly) as you are flying over the weeds. This would create a "reveal" without actually moving around an object.
KNOW that with experience and confidence you can achieve spectacular results even when not adhering to ANY of the above steps!
