SUMMARY
Photographer John Gress demonstrates how to backlight subjects at the beach to avoid harsh shadows and blown-out skies. His method involves setting aperture for depth of field, adjusting shutter speed to control background exposure, and then dialing in flash power. Gress utilizes high-speed sync, often at shutter speeds between 1/6,400 and 1/8,000 of a second, to freeze fast action while preserving sky detail. This technique, combined with matching artificial light to ambient conditions and using compositional elements, helps create well-exposed and visually appealing outdoor portraits.
TAKEAWAYS
Use a formula: aperture, shutter speed, then flash power for exposure.
High-speed sync is essential for fast shutter speeds outdoors.
Balance flash output with aperture and shutter speed to retain sky detail.
Match artificial light quality to ambient light for a natural look.
