If it is an underwater drone with camera, lighting will be an issue.
Lights being needed at night and at deeper depths.
Lights close to drone body will cause light to be reflected from any suspended material in water, ruining images.
Lighting correction with lights off will be needed due to loss of warm colors (Red at 5-meters, Orange at 10-meters, Yellow at 20-meters), deeper drone goes. Or with lights on distance to subject becomes an issue.
Examples:
Day time, subject down 5-meter in water, drone camera 5-meters away from subject reflected light, total total of 10-meters - loss of Reds.
Night time, drone 5-meters from subject, light from drone 5-meters to subject, reflected light 5-meters back to drone camera, total 10-meters - loss of Reds.
