When photographing underwater objects, where should the flash or underwater light be aimed?

When photographing underwater objects, aiming the flash or underwater light at the actual distance to the object is crucial for achieving the best results. This method ensures that the light effectively illuminates the subject by minimizing the amount of water between the light source and the object. If the light is aimed directly at the object from the correct distance, it enhances color saturation and reduces backscatter from suspended particles in the water, which can otherwise create a hazy image.

This approach allows for a more controlled lighting situation, helping to prevent overexposure or underexposure that can occur if the light is not appropriately positioned. This technique is especially important in underwater photography where light behaves differently than it does in air, losing intensity and color temperature as it passes through water.

Aiming light directly above the object does not adequately address the specific distance and angle required to illuminate the object appropriately. Pointing it outwards towards the surface or away from the object would result in poor visibility and lack of detail, as the light would not be directed where it is needed most, leading to dim and unappealing images.
