In the captivating underwater world of shipwrecks, photographers face unique challenges when it comes to capturing striking images in low light conditions. Here are some techniques that can help you create atmospheric wreck photos under challenging circumstances.

Firstly, using a wide aperture (low f-stop) is recommended to maximize light entry, while carefully lowering the shutter speed to balance light intake without causing motion blur, and increasing ISO to improve exposure while managing noise. Mastery of your equipment to operate settings efficiently in the dark is crucial.

For lighting, combining artificial light sources such as strobes, diver torches, and continuous video lights is essential. Positioning the light to create interesting silhouettes, contrasts, and shadows adds drama to wreck compositions. Using custom white balance settings helps maintain accurate colours under varying light sources.

When it comes to colour correction filters, they can help restore warm tones lost at depth, but their effectiveness in very low light may be limited. Black and white photography is often an excellent choice for wrecks, emphasizing strong shapes, form, and contrast. Shooting in RAW allows for greater post-processing flexibility, and emphasizing contrast, texture, and composition is key.

Ambient light is often the best choice for capturing the entire wreck with a wide-angle lens. Strobes should be pushed out far to the side to reduce backscatter. Good buoyancy and fin kicking technique (frog kicks) are important when inside a wreck to avoid silting up the area.

For large wrecks, having a diver in the photo can help show a sense of scale. The Japanese fishing wreck in Bali was photographed using a Nikon 10.5mm fisheye lens, F10, 1/125th, ISO 100. The wreck of the Ann was photographed while diving Solomon Islands.

Black and white photography is often an excellent choice for wrecks, emphasizing strong shapes, form, and contrast. The best lenses for wreck photography include ultra-wide lenses such as a 10.5 or 10-17mm fisheye, or a 10-20 rectilinear.

Close-focus wide-angle (CFWA) is effective for soft-coral encrusted wrecks. Even at 1/25th, a wreck photo can be sharp when shooting very wide, as demonstrated in a photo from the Catalina Island dive park. When shooting wrecks from far away, it's important to turn off strobes.

For example, the Nippo Maru wreck in Truk Lagoon was photographed using a Nikon 12-24 lens, F6, 1/25th, ISO 500. The challenge was to get the entire bow of the wreck and still show detail of the diver. Having a very wide angle lens for this shot made it possible.

In summary, the key techniques are:

• Wide aperture, slower shutter speed, and balanced ISO for exposure
• Artificial lighting (strobes, torches) to restore colour and contrast
• Experimenting with white balance for natural tones
• Using filters selectively, mainly for colour correction
• Strong focus on composition and contrast for black and white images
• Mastery of buoyancy to avoid disturbing sediment that reduces clarity

These approaches will help create striking, atmospheric wreck photos under challenging low-light underwater conditions.
