Strobe Placement & 8 Easy Tips for Lighting Your Subjects

One of the most frequent underwater photography questions I hear is, "Where do I put my strobes?" While there is no single solution that works for every situation - and rules are meant to be broken - here are some tips that will help you get the light in the right direction.

Get Close

Try to stay within a few feet of your subject to get the most light, contrast and color from your strobes. Even at five feet away, your contrast and color will start to drop, even in the best visibility.

Strobe Placement Tight

One Strobe or Two?

For macro shooters, you can get away with a single strobe. Adding a second strobe will allow you to fill shadows created by the primary. For wide-angle photography, a pair of strobes is recommended. Dealing with shadows and a wide coverage area is much easier to accomplish with two strobes.

Keep 'Em Up

Natural light comes from above. Light from below is unnatural, which is why telling ghost stories with a flashlight under your chin is spooky. Keep your strobes above the level of your camera lens to avoid spooky lighting.

Wide-Angle Shooting

This is more difficult, as strobe placement becomes more critical the wider you go with your lens. As a general rule, keep your strobes pointed forward, not inward, and have about the same distance from the strobe to the housing as you have from the lens to the subject. This avoids lighting up the tiny particles in the water - backscatter- by creating a "dark zone" between the camera and the lens.

Strobe Placement Wide

Macro Shooting

Strobes have an angle of about 90 degrees or more; your subjects will be at 30 degrees or less. Like the scattered shot of a shotgun, you can aim strobes in the general direction and still hit the target. Strobes will be placed close to the camera, facing forward. With a single strobe, place it on top. With a pair, I like to have one on top of the camera and one on the side, allowing me to switch to a vertical composition, and still have one on the top and one on the side.

8 Easy Tips for Lighting It Right

  1. Always keep your strobes pointed forward, not inward.
  2. As you get closer to a subject, bring the strobes closer to the housing. (above, left)
  3. As you get farther away, push them out wider. (above, right)
  4. If you see backscatter while reviewing your image, push the strobes out wider for your next shot.
  5. Reposition your strobe if it is lighting an ugly area of the reef.
  6. If one strobe is significantly closer than the other, turn down the intensity of the closer strobe to avoid blowing out the exposure.
  7. For wide-angle vertical shots, try turning off one strobe and just use the one on top.
  8. For wide-angle shots with a wall on one side, position one strobe on top and another on the blue-water side.

Sunballs - 7 Illuminating Tips to Get Better Shots
Though they are beautiful to see underwater and they add a stunning element to your underwater photos, sun balls can be tricky, as you'll be shooting at the limits of your camera's capabilities. These tips will help you get the most out of your SLR or mirrorless camera.

The Best DSLR Camera Settings for Underwater Photos
Let's face it, while today's DSLR cameras have tons of features and menu items for customization, that can be overwhelming to the new shooter, or to one who makes only a couple of dive trips a year. Worse yet, some settings could give the false impression that your equipment is faulty, when a simple setting change solves the problem. Here are our best tips for getting started.

Mastering Macro Underwater
Generally, anything small enough to fit within a 5-by-7-inch area is considered macro. Lots of subjects fall into this category — fish, crustaceans, abstract details and more. Photographing subjects this small requires getting close and using special macro lenses.

5 Tips For Pro-Looking Photos From Your Compact Camera System
Shooting in RAW, adding a strobe, taking control of your exposure, getting closer, and using macro mode will be discussed in these 5 tips to get professional looking photos from your compact camera system.

Wide-Angle – Easy Tips for Underwater Photos
Anything that’s larger than a basketball should be considered a wide-angle subject. By using a wide lens with at least 100 degrees of coverage, you can get within inches to a few feet of your subject and still maintain an expansive background.
