This combination helps ensure that your subject is beautifully illuminated without overexposing the background or other surrounding elements in the scene.

For those who prefer more control over their lighting setup, the strobe’s power can also be manually adjusted. This flexibility allows you to fine-tune the exposure based on the particular lighting conditions of your dive, ensuring that every shot is perfectly exposed, even in more challenging environments. However, it is important to remember that underwater environments often present low-light situations, and your lighting adjustments may vary depending on the depth, water clarity, and natural light availability.

Choosing the Right Aperture for Macro Photography

Macro photography with the Olympus OM-D E-M5 Mark II opens up a world of creative possibilities, and selecting the right aperture is one of the most critical aspects of achieving stunning results. When photographing small marine subjects like nudibranchs, shrimps, or coral details, a smaller aperture such as f/22 is recommended. This setting ensures a greater depth of field, which is essential for keeping the subject sharp from the front to the back, given the tiny scale of the creatures being captured. The resulting images will exhibit a high level of detail, revealing the textures and fine features that make macro photography so captivating.

However, it’s not always about maximizing depth of field. In certain situations, especially when photographing larger subjects like fish or marine plants, you may want to open up the aperture to f/8 or f/5.6 to allow more light into the lens. A wider aperture in such cases can help illuminate the subject and ensure that the image is bright enough for clarity. This setting also makes it easier to use the camera’s built-in strobe or external lighting effectively, providing a good balance between subject lighting and background exposure.

Another useful technique when capturing macro shots, particularly for those who enjoy creating artistic, visually striking images, is to use a wider aperture such as f/2.8 or f/5.6. These apertures help to isolate the subject from the background, creating a dreamy, blurred effect known as bokeh. This technique allows you to focus attention solely on the main subject, making it stand out against a soft, diffused background. When the background is blurred, it draws the viewer’s attention to the fine details of the subject, whether it’s the delicate texture of a seahorse’s skin or the intricate patterns on a coral reef. It’s a great way to emphasize the beauty of a subject and add depth to the image.

Working with Lenses and Close-Up Techniques for Macro Photography

The lens you use plays a vital role in how close you can get to your subject and the amount of detail you can capture. The Olympus OM-D E-M5 Mark II is compatible with a variety of lenses, each offering different strengths for macro photography. Popular choices include the 45mm and 60mm macro lenses, both of which are excellent for capturing fine details in small subjects like shrimp, starfish, or even the tiny bubbles that float through the water. These lenses allow you to get up close to your subject while maintaining exceptional sharpness and clarity.

When working with the 45mm or 60mm macro lenses, you can experiment with a wider aperture to create a shallow depth of field, further enhancing the bokeh effect and allowing you to isolate your subject. If you’re photographing larger subjects, such as fish, it is important to adjust the aperture to around f/8. This setting ensures enough light reaches the subject while still maintaining some depth of field for sharpness. Since the smaller apertures like f/22, will limit the reach of your strobes, adjusting the aperture to a slightly wider setting ensures well-lit images with proper exposure.

For a more versatile approach, the 12-50mm lens is also an excellent option, especially in its macro mode. This lens offers a wider field of view, which can be useful when photographing larger subjects or when you want to capture more of the surrounding environment along with your subject. The lens’s macro mode lets you zoom in on smaller creatures while maintaining a solid level of detail, providing flexibility in various underwater shooting scenarios. The 12-50mm lens allows you to quickly adjust between wide-angle and macro shots without the need to switch lenses, making it a convenient tool for underwater photography.

When working in close quarters with subjects in macro photography, particularly with a wet diopter, it’s crucial to zoom in fully to capture the subject with the highest level of detail. The working distance between you and the subject in such cases will be very limited, so being patient is key. Moving too quickly or causing disturbances can startle your subject, causing it to swim away or change its position, making it harder to capture the shot. To avoid this, take slow, deliberate movements and get as close as possible to fill the frame with your subject. This technique ensures that your shot is as sharp and detailed as possible, allowing you to showcase the beauty of the subject with minimal distractions.

In certain situations, you may find that even with the best settings, the subject remains too dark or lacks proper exposure. To address this, try adjusting the strobe’s output manually based on the available lighting conditions.

Choosing the Right Lens for Wide-Angle Shots

When it comes to wide-angle underwater photography, selecting the right lens is critical. Popular lens choices for these types of shots include the 8mm fisheye and the 9-18mm wide-angle lens. These lenses provide a wide field of view and the ability to capture expansive scenes, which is ideal when shooting large reef formations, schools of fish, or dramatic underwater topography. The 8mm fisheye lens, in particular, gives a unique perspective with its circular distortion effect, making it a favorite among underwater photographers looking to emphasize the immersive depth of the ocean.

For optimal results, it's important to set your camera to manual mode, which gives you full control over your exposure settings. Begin with an aperture of f/8, a shutter speed of 1/125th of a second, and ISO 200. These settings serve as a good baseline to ensure sharp focus and proper exposure. The key to great wide-angle photography is managing the balance between ambient light and artificial flash. The flash in TTL (Through The Lens) mode should be used to illuminate your primary subject, while the surrounding ambient light from the environment fills in the background, creating a natural sense of depth.

Balancing Exposure with Shutter Speed

Shutter speed plays a crucial role in wide-angle underwater photography, especially when it comes to capturing the right amount of ambient light. A faster shutter speed, such as 1/250th of a second, is perfect when shooting in well-lit conditions or in shallow waters where the sunlight can easily reach the scene. In these conditions, the fast shutter speed will ensure that your images are bright, with minimal motion blur. On the other hand, deeper waters often come with less ambient light, requiring slower shutter speeds, such as 1/60th of a second or even slower. Slowing down the shutter allows more light to hit the sensor, ensuring that your image is properly exposed despite the darker conditions.

When shooting near the water’s surface, especially if the sun is in the frame, using a higher shutter speed is vital to prevent overexposing the highlights. Direct sunlight can cause parts of the image, particularly those near the surface, to become blown out. By increasing the shutter speed, you can control the light coming into the frame and capture a more balanced exposure. If the sun is a prominent part of your composition, shooting at a faster shutter speed also helps preserve the bright highlights while maintaining detail in the shadows. In these scenarios, an aperture setting like f/16 or f/22 works well to avoid overexposure of bright areas.

Leveraging Ambient Light and Adjusting for Natural Conditions

While artificial lighting, such as flashes and strobes, can significantly enhance your wide-angle underwater shots, ambient light is an essential element in capturing the natural beauty of the underwater world. If you prefer to shoot with natural light, or if you're diving in areas with sufficient sunlight, you'll want to adjust your settings to make the most of what the environment offers.

In this case, opening up the aperture to f/5.6 or even f/4 can help gather more light, especially when the lighting is dim or when shooting at greater depths. Additionally, you may need to increase your ISO to compensate for the reduced light. Depending on the situation, ISO values of 400, 800, or even 1600 may be necessary to maintain a properly exposed image. Higher ISO settings can introduce some noise, but with the right post-processing techniques, this can often be minimized, allowing you to retain the atmosphere of the shot.

For optimal natural lighting, try to position yourself with the sun behind you. This ensures that the light evenly illuminates your subject, providing a well-lit scene without harsh shadows or overexposure. Shooting at the right angle to catch the light can make a dramatic difference, especially when you're aiming to highlight the textures and colors of coral reefs or marine creatures. Additionally, fine-tuning your white balance settings can help you achieve the desired color tones in the final image, ensuring the scene’s hues reflect the natural beauty of the underwater world.

Flash Settings for Wide-Angle Shots

Flash is a crucial tool when it comes to wide-angle underwater photography, as it helps to light up your subject while still allowing ambient light to fill the background. However, managing flash power and its positioning can be tricky, especially when using wide-angle lenses like the 8mm fisheye. This lens has a unique characteristic of exaggerating the distance between the subject and the background, which can result in uneven lighting or harsh shadows if the flash is not adjusted properly.

When using a fisheye lens, it's essential to ensure that the flash illuminates not only the subject but also the edges of the frame. Because fisheye lenses have such a wide field of view, the light must be evenly distributed across the entire scene to avoid areas that are too dark or too bright. Adjusting the flash power and experimenting with the distance and angle of the strobes will help you achieve a balanced exposure across the entire frame.

Flash placement is also crucial when shooting subjects that are close to the camera. If your subject is too close, the light from your flash can create harsh shadows or cause overexposure. To prevent this, try positioning the strobe at an angle, rather than directly in front of the subject, which will help diffuse the light and reduce the likelihood of creating unwanted shadows.

Getting the Most Out of Your 8mm Fisheye Lens

The 8mm fisheye lens is particularly popular in wide-angle underwater photography for its ability to offer an ultra-wide perspective, allowing photographers to capture large areas of the underwater environment. This lens is ideal for shooting expansive coral reefs, underwater caves, or vast schools of fish, as it provides a broader field of view compared to traditional wide-angle lenses.

However, because of its distinctive barrel distortion, the 8mm fisheye lens can present challenges in achieving even lighting. The light from your flash may not cover the edges of the frame effectively, leading to an uneven exposure. To mitigate this, make sure to carefully adjust the flash power to ensure that the entire scene is illuminated evenly. By experimenting with different strobe settings and flash positions, you can find the right balance and create dramatic images that capture the vastness of your surroundings without harsh light spots or overexposure.

The fisheye lens also requires you to pay close attention to the distance between the subject and the background. This lens tends to exaggerate the sense of space, which can create a dramatic, almost surreal effect. It’s important to adjust the positioning of both the camera and the strobe to achieve the desired perspective and lighting. The wide-angle capabilities of the 8mm fisheye lens, combined with careful flash management, allow you to capture images that are both striking and immersive.
