Capturing beautiful aquarium fish photos can be challenging, especially when glare from the glass interferes with your shots. Glare can obscure details, cause unwanted reflections, and ruin the vibrant colors of the fish. Fortunately, with the right techniques and a few simple adjustments, you can take stunning aquarium fish photos without any glare. Here’s how to do it.

1. Choose the Right Camera Settings
The first step to avoiding glare in aquarium fish photography is adjusting your camera settings. Using the correct settings will help minimize the amount of light that reflects off the glass and ensure your subject is properly lit.
Use a Fast Shutter Speed:
Set your shutter speed to at least 1/250 seconds to freeze the motion of the fish and reduce the chance of glare caused by long exposure times. A faster shutter speed will also help reduce blur and ensure sharper images.
Adjust the ISO:
Keep your ISO low, ideally between 100 and 400, to reduce noise and maintain image clarity. However, in low-light environments, you may need to increase your ISO to allow more light into the camera.
Set the Aperture Correctly:
A wider aperture (lower f-number, such as f/2.8 or f/4) allows more light to hit the sensor and helps create a shallow depth of field. This can isolate your fish from the background and blur the glass reflections. Experiment with different apertures to find what works best for your shots.
2. Position Yourself to Avoid Reflections
Positioning yourself correctly is key to avoiding glare. Reflections often occur when the camera lens is too close to the glass or when the light source hits the glass at the wrong angle.
Avoid Directly Facing the Tank:
Instead of shooting straight on, move to an angle. This can help eliminate reflections and glare that often appear when the camera is too close or directly facing the glass. A 30- to 45-degree angle is ideal for minimizing reflections.
Stay Close to the Glass:
Being close to the aquarium glass helps reduce the chance of reflections. The closer you are, the less light bounces off the glass and enters your lens. However, don’t get too close to the glass, as it can create unwanted distortion in your images.
Lower Your Camera Position:
Shoot from a lower angle or even at water level. By positioning your camera near the water’s surface, you reduce the chances of reflections from overhead lighting and eliminate glare from the surface of the glass.
3. Control the Lighting
Lighting plays a crucial role in aquarium photography, and improper lighting can create glare or wash out your fish’s colors. Controlling the lighting source will significantly improve your shots.
Use Soft, Diffused Lighting:
Harsh lighting creates reflections and glare, so opt for soft, diffused lighting. You can use a diffuser or even a white cloth to soften the light before it hits the tank. This will help illuminate the fish without creating unwanted reflections.
Turn Off Tank Lights:
Aquarium lights can cause glare when combined with overhead or natural light sources. Turn off your aquarium lights and rely on external lighting, like a softbox or LED panel, to provide the necessary illumination. This will reduce reflections that often come from the tank lights.
Avoid Overhead Lighting:
Overhead lights are one of the main culprits of glare in aquarium fish photography. Try to avoid shooting when the room lights are on above the tank. If possible, shoot during the day when natural light from windows is available, or position external lights in a way that minimizes reflections.
4. Use a Polarizing Filter
A polarizing filter can be a game-changer when it comes to aquarium fish photography. This filter reduces glare and reflections by blocking specific light waves from entering the lens. By rotating the filter, you can adjust the amount of reflection you want to eliminate.
How to Use a Polarizing Filter:
Attach the polarizing filter to your camera lens and adjust it until you see the glare diminish. This filter works best when shooting at an angle to the glass, as it reduces the amount of light reflecting off the surface. It also enhances colors, making the fish look more vibrant in your photos.
5. Focus on the Fish, Not the Glass
To ensure your fish is the star of the shot, focus on the fish rather than the tank glass. When you focus on the fish, the glass will often appear blurred, making the glare less noticeable.
Use a Wide Aperture for Shallow Depth of Field:
By using a wide aperture (such as f/2.8 or f/4), you create a shallow depth of field, which blurs the background, including the glass. This technique helps keep the fish in focus while softening any reflections in the tank.
6. Take Multiple Shots and Edit Later
Even with the best setup, glare can sometimes still sneak into your photos. Don’t be discouraged. Take several shots with different angles, camera settings, and lighting to increase your chances of getting a perfect shot.
Edit Your Photos:
Use photo editing software, like Lightroom or Photoshop, to further reduce glare. You can adjust exposure, contrast, and highlights to enhance the details of the fish and minimize any lingering reflections.
Conclusion
Taking aquarium fish photos without glare requires a combination of the right camera settings, careful positioning, and proper lighting. By using these techniques, you can eliminate reflections, capture stunning details, and highlight the natural beauty of your fish. Remember to experiment with different angles, use a polarizing filter, and focus on lighting to create the best aquarium fish photos possible.
