What the AI looks for in Underwater Strobes & Flashes
- Guide number vs. lens
- Use more output for wide-angle at distance. Macro needs far less power and benefits more from recycle speed. Water absorbs light quickly, so wide scenes need much more power.
- Beam angle
- Strobe coverage should match your widest lens, with diffusers as needed. A narrow beam leaves dark corners on fisheye shots.
- Triggering
- Use fiber-optic for most housings and electrical sync only with matching housings. The triggering method must fit your housing's ports.
- TTL support
- Confirm the strobe and housing trigger (optical or electronic) support TTL for your camera, or plan on shooting manual. Not every combination gives working TTL.
- Recycle and batteries
- Check recycle time at the power you will use, and AA versus proprietary battery availability on trips. Slow recycling makes you miss moments, and odd batteries are hard to replace at remote dive sites.
Brands that matter
- Sea & Sea: Mainstream fiber-optic strobes with broad support.
- Inon: Compact, wide-beam strobes with good accessories.
- Backscatter: Modern compact and high-power strobes.
- Retra: Premium strobes with strong light-shaping options.
- Ikelite: Electrical-sync strobes for Ikelite housings.
- Kraken Sports: Lower-cost strobe options.
What to avoid
- A strobe that cannot be triggered by your housing type
- Buying one tiny strobe for wide-angle scenes
- Skipping diffusers on wide-angle shots
Questions
One strobe or two?
One works for macro. Two give even wide-angle coverage and fewer shadows.
