What is Freeze Function?Updated 21 days ago

The Freeze mode on FJ Westcott strobes allows photographers to record incredibly fast-moving subjects with precision. This feature helps you "freeze" motion efficiently by providing the shortest flash durations, making it suitable for high-speed photographic conditions.

• What does the Freeze function do, and when should it be used?

  • The Freeze mode creates the shortest flash duration possible. It is perfect for circumstances of very fast movement, allowing you to photograph fast-moving subjects like water drops with minimal to no motion blur.  To avoid light contamination, decrease or remove any ambient¸ light in your scene, and make sure the flash duration is quick enough to effectively freeze the motion.
    
    

• How does the Freeze function affect flash duration and power levels?

  • The lower the power setting, the shorter the flash duration in Freeze mode. You may need to adjust power settings and camera settings according to your shooting needs for optimal performance.
    
    

• What happens to the color temperature?

  • While FJ strobes are calibrated for a consistent 5500K color temperature. Using the Freeze function will make the light noticeably cooler. For the most accurate results, consider using a custom white balance and/or a gray card when activating Freeze mode.
