How many lumens do I need for underwater video?
For underwater video, you’ll need lights that are 1,000-5,000 lumens or more, depending on the depth and visibility. Shallow, clear waters may only require 1,000-2,000 lumens, but for deeper or murkier conditions, brighter lights (3,000-5,000+ lumens) are necessary to illuminate your subject and counteract light and color loss.
Do you need lights for underwater photography?
Yes, lights are highly recommended for underwater photography, especially at depths where natural light diminishes. Without additional lighting:
- Colors appear muted or blue/green due to light absorption.
- Details can be lost in shadows, especially in macro photography or videos.
Strobes or video lights help bring out the vibrant colors of marine life and improve image sharpness.
Do fish like underwater lights?
Fish can be both attracted to and startled by underwater lights, depending on the species and light intensity. Some fish are naturally drawn to lights as they mimic bioluminescence, while others may shy away due to the brightness. Lower-intensity, well-positioned lights tend to disturb marine life less.
Should you use one or two lights for underwater video?
Using two lights is ideal for underwater video. Two lights:
- Provide balanced lighting, reducing harsh shadows.
- Offer better coverage and flexibility, especially for wide-angle scenes.
- Allow for creative effects, such as backlighting or highlighting specific areas.
A single light can still work but may create uneven lighting or shadows.
How to position underwater video lights?
Proper positioning ensures even lighting and minimizes backscatter:
- Place lights away from the camera lens: Position lights at a 45-degree angle to reduce particles reflecting light directly back into the lens.
- Adjust light distance: Keep lights close to the subject to maximize brightness and reduce the impact of water particles.
- Avoid overexposing: If your subject is brightly colored, use diffusers or lower light intensity to avoid washing out details.
- Use two lights symmetrically: For wide shots, angle each light slightly outward to cover more area evenly.
- Experiment with angles: Adjust the light positions for macro or wide-angle shots to create the desired effect and minimize shadows.
Practice and small adjustments will help you achieve optimal results in various underwater conditions.
