Underwater portraiture is a beautiful medium with many factors to consider that can’t be addressed within a single post, so we’ll start off here by focusing on one aspect: directing the light. Just like above water, the direction and quality of the light dramatically change the look of the portrait.
Choosing a Lighting Source for Underwater
Underwater strobes and lights get expensive and require special camera housings to truly be effective. I’ve seen ingenious ways to get strobes fired from above the pool to be reflected down into the pool, and these can be a novel, but difficult, solution without equipment specially designed for it. However, a simpler solution is to use the power of the sun to our advantage in lighting our underwater portraits.
When to Shoot Underwater?
As photographers, we often crave the Golden Hours of sunrise and sunset, for good reason. The light is soft, and the low long shadows and softer warm light can be used to great effect. This happens to translate into the underwater environment as well. It is the easiest time of day to work as it provides the most control over the lighting.
For underwater photography, we can use this to our advantage in a way that is unique due to how the light bounces when it hits the water’s surface. I want to control the light for a portrait even when shooting underwater, I don’t like having the sun hitting the surface of the water directly, causing refractive patterns that scatter the light. This happens when the sun is shining directly on the surface of the water and is disturbed through waves, splashes, or even slowly moving around in the pool.
The light can hit the skin in unflattering ways that are difficult to control, even if the result is as beautiful as the image on the right shows. So, for the left image of the bride we waited until the sun was low enough on the horizon that the pool was fully in the shade. I wanted that soft light. I really can get a fantastic image with just the soft light from the shaded pool. It creates a dreamy look, almost ethereal.
Directing the Light
To add dimension, and depth that comes from a more directed light, I would need to add light to the underwater environment. In this case, it comes from a giant reflector (4feet by 8 feet). My assistants and I are directing the sun on her creating a spotlight of bounced light. Normally, if we are going through a photography catalog, a reflector that size would be prohibitively expensive. However, home improvement stores often have “photography” equipment for a bargain basement price. A piece of foam insulation paneling with a silver reflective surface in a variety of thicknesses is less than $15. It’s big, it’s bulky, but it is light and disposable (or can be saved for your next project). You can’t do this alone. It isn’t a solo endeavor, but with two assistants on the side of the pool, holding the reflector we have a moveable spotlight to direct on the subject, controlling the light.
