My flash seems to always lose power when I use High-Speed Sync Mode compared to when not using High-Speed Sync mode. Is there something that I'm doing wrong, or is there a problem with my flash?
- Losing about a stop of power when using High-Speed Sync (HSS) mode compared to the flash output when not using HSS mode is normal. HSS works by rapidly pulsing the light from the flash (quicker than the eye can see) so that light gets to all parts of the sensor, which gives you even flash coverage across the entire sensor. However HSS it does have a few drawbacks:
- Since the Light has to pulse, you do lose a fair bit of flash output, meaning that you will have to compensate by moving your flash closer to your subject.
- It also requires a fair amount of power to perform High-Speed sync, which drains your batteries quicker than normal.
To see a more in-depth explaination of how High-Speed Sync works, please refer to our True High-Speed Sync vs Long Tail High-Speed Sync Blog Post
Does the CITI400Pro offer manual adjustment in 1/10th (0.1) stop increments?
