Master Flash Photography in Bright Sun with This One Technique
Shooting in bright sunlight can be tricky. Wide-open lenses, harsh shadows, and blown-out highlights often make photographers feel stuck. But there’s one technique that changes the game: high-speed sync (HSS) with your flash.
In this post, we’re breaking down a real behind-the-scenes session showing how to use HSS to get beautifully exposed images, even under the brightest sun.
1. The Challenge of Bright Sun
Shooting wide open in bright light is a challenge. Without HSS, you’re limited to your camera’s maximum flash sync speed—usually around 1/200–1/250 sec. Trying to expose at f/1.2 or f/2 at this shutter speed often blows out the background, making it impossible to capture the scene properly.
Here’s the problem:
- Shutter speed too low → background overexposed
- Shutter speed too high → flash can’t fire properly
This is where high-speed sync saves the day.
2. What High-Speed Sync Does
High-speed sync allows your flash to fire multiple rapid bursts, letting you raise your shutter speed above the normal sync limit.
The benefits:
- Shoot wide open for beautiful background blur
- Maintain proper exposure of bright scenes
- Keep your subject lit naturally without harsh shadows
In the session, we raised the shutter speed to around 1/2500 sec at f/1.2, keeping the background properly exposed while using flash to fill in the subject.
3. Setting Up Your Flash
Here’s a step-by-step breakdown from the session:
- Choose your light: We used a Profoto B10 with a beauty dish for soft, flattering light.
- Position strategically: Keep the flash on the same side as the sun, slightly feathered, so it blends naturally.
- Manual control: Dial in your flash manually, starting at full power if it’s bright outside.
- Adjust for flare: Move the subject slightly or adjust flash height to control reflections and avoid unwanted highlights.
- Check background: Use your shutter speed and aperture to blur distractions, like cars or harsh light, while keeping your subject crisp.
4. Posing and Natural Interaction
Even with technical mastery, natural posing matters. Tips from the session:
- Have your subject move slightly to feel relaxed
- Play with arms, hair, and subtle gestures to add natural flair
- Position them in slight shade or against reflective surfaces to balance the sunlight
The result is a perfectly exposed, beautifully lit image with depth, dimension, and personality.
5. Key Takeaways for Photographers
- High-speed sync is essential for shooting wide open in bright light
- Flash positioning matters—feathering toward the subject creates soft, natural light
- Manual settings are your friend—start full power, adjust as needed
- Movement and natural posing make the flash feel seamless, not staged
With HSS, you can combine the drama of a wide-open lens with the control of flash, even under the harshest daylight conditions.
6. Final Thoughts
Bright sunlight doesn’t have to be your enemy. Using high-speed sync flash opens up creative possibilities for outdoor portraits, engagement sessions, or any shoot in harsh daylight. It allows you to control light, exposure, and focus creatively, giving your images a professional, cinematic look.
If you’re ready to stop fighting the sun and start mastering it, high-speed sync is your secret weapon.
