Mastering High-Speed Sync with the Fujifilm GFX 100 II and Profoto Air Remote TTL-F
When Fujifilm unveiled the GFX 100 II, it brought a blend of medium format quality and cutting-edge features that have photographers buzzing. Pair it with Profoto’s Air Remote TTL-F, and you unlock the full potential of High-Speed Sync (HSS) for creative lighting. But how do these two powerhouses work together? Let’s break it down and explore how to take your photography to the next level.
Why High-Speed Sync on Medium Format?
The GFX 100 II’s 102MP sensor and expanded video capabilities make it a versatile choice for both stills and motion. However, its focal-plane shutter limits native flash sync to 1/125 second—a typical challenge for medium format systems.
Enter High-Speed Sync (HSS): By pulsing light at incredibly high speeds, Profoto flashes allow you to sync your flash at shutter speeds up to 1/4000 second. Whether you’re shooting outdoor portraits in bright sunlight or freezing motion with a wide aperture, HSS opens creative doors once thought closed for medium format users.
The Gear Setup
Here’s what you need to get started:
• Fujifilm GFX 100 II: With improved autofocus and processing power, it’s perfect for fast-paced shoots.
• Profoto Air Remote TTL-F: Designed for Fujifilm, this remote integrates seamlessly with the GFX 100 II.
• Compatible Profoto Flash: Popular options include the B10X, B1X, and the studio-grade Pro-11.
Pro Tip: Update the firmware on both your camera and the Air Remote TTL-F to ensure compatibility and optimal performance.
Getting HSS to Work
1. Attach the Profoto Air Remote TTL-F
Slide the remote into the hot shoe of your GFX 100 II. Set the remote to TTL mode initially for quick, accurate flash output.
2. Activate HSS Automatically
On the GFX 100 II, set your shutter speed beyond 1/125 second. The Profoto system will automatically switch to HSS mode.
3. Switch to Manual for Fine Control
Once you’ve dialed in your composition, switch to manual mode on the Profoto remote to tweak power settings. HSS can be power-hungry, so consider increasing the flash output or bringing the light closer to your subject.
Creative Applications of HSS
1. Balancing Sunlight with Flash
Medium format excels in dynamic range, but even the GFX 100 II struggles to tame harsh midday sun without help. With HSS, you can shoot at 1/2000 or 1/4000 second, darkening the ambient light while keeping your subject well-lit with flash.
Example: A fashion shoot in broad daylight where you want to isolate the model against a moody, underexposed background.
2. Freezing Motion
HSS lets you freeze motion, whether it’s a dancer mid-leap or water splashing dramatically. The GFX 100 II’s autofocus enhancements ensure you won’t miss a moment.
Example: Capture a dancer backlit by the sun while maintaining sharp detail and a dramatic wide aperture.
3. Creative Depth of Field
Shooting medium format with fast lenses (like the GF 80mm f/1.7) creates dreamy bokeh, but bright environments often force you to stop down. HSS enables you to shoot wide open even in full sunlight.
Example: A cinematic environmental portrait with creamy bokeh in a bustling urban setting.
Challenges and Solutions
• Battery Drain: HSS uses more power, both from the flash and the camera. Bring spare batteries for longer shoots.
• Limited Flash Range: HSS reduces effective flash range. Solve this by positioning your light source closer or using a modifier like a beauty dish or softbox.
• Timing Precision: The GFX 100 II’s advanced metering and improved processor minimize HSS timing errors, but test your setup beforehand to avoid surprises.
Conclusion
The Fujifilm GFX 100 II paired with the Profoto Air Remote TTL-F brings a world of creative possibilities to medium format shooters. Whether you’re a portrait artist, commercial photographer, or fine art creator, mastering HSS gives you the tools to conquer challenging lighting scenarios with precision and style.
So, grab your gear, find your light, and take full advantage of what HSS can do for your photography.
