Final answer:
The best overall angle for underwater photography is 45 degrees relative to the water's surface.
Step-by-step explanation:
The best overall angle for underwater photography is 45 degrees relative to the water's surface.
At this angle, the light from the subject underwater will undergo total internal reflection when it reaches the water's surface. This means that all the light will be reflected back into the water, resulting in a clear and vibrant image.
To achieve this angle, the photographer can use a combination of diving techniques and camera positioning to ensure they are shooting at the optimal angle.
