- Arrive early—as soon as the aquarium opens—to avoid crowds. And if you have the choice, stick with aquariums that permit the use of tripods.
- Avoid distortion by placing your camera parallel to the glass wall of the tank.
- Turn off on-camera flash to prevent distracting reflections.
- Focus on nearby creatures.The more water between your camera and your subject, the softer the focus will be.
- Include human silhouettes. They'll inject an important sense of scale and dimension.
- Concentrate on light, silvery fish rather than darker species, which can blend into backgrounds.
- Use a high-speed lens so you can set fast, action-stopping shutter speeds. Slow-swimming fish are easier to capture sharply than darters.
- Consider combining images with software, as Ford did for the image shown here. Because it's hard to catch multiple species attractively in a single shot, he made separate photos of the fish in this tank. He combined them in Adobe Photoshop later using layers and masks.
