We can distinguish three ways of taking photos, each with its difficulties and risks.
The final price will depend, among others, on that method of capture.
Ground
When the photographer takes his shots with a "classic" camera from land, he is placed in the Ground category.
Agua
When the photographer shoots from the water, with his camera inside a waterproof case and fins (or from a boat). This mode of shooting is more physical and involves more risks than the Ground method.
Drone
When the photographer shoots with a drone.
