What is Flash Exposure Compensation? How to Use It?
Flash Exposure Compensation (FEC) lets you control your flash’s brightness without changing your camera’s overall exposure. It’s useful when your flash is too strong or too weak, allowing you to fine-tune the light for a more natural look. In this video, I’ll explain what FEC is, how it works, and when to use it for better flash photography. Whether you’re using TTL or manual mode, mastering FEC will help you get perfect lighting every time!
This video is from our Off-Camera Flash Photography Course.
Video Summary:
This tutorial explains Flash Exposure Compensation (FEC) within TTL (Through-The-Lens) flash mode. While TTL automatically determines flash power, FEC allows you to manually fine-tune it. If the auto result is too bright, you can apply negative compensation (e.g., -1, -2) to reduce the flash output. If it’s too dark, you can apply positive compensation (e.g., +1, +2) to increase it. This gives you creative control over the flash exposure without leaving the convenient TTL mode. The video demonstrates this with a series of photos showing the same scene shot at different FEC values.
Timestamps:
0:26 – Introduces the problem: You might not be happy with the automatic flash output from TTL mode.
0:50 – Contrasts this with Manual mode, where adjusting power is straightforward.
1:07 – Introduces the solution: Flash Exposure Compensation (FEC) in TTL mode.
1:19 – Shows how to access FEC on the flash, displaying values like +1 or -1.
1:44 – Explains FEC: It instructs the TTL system to fire slightly brighter (+ values) or darker (– values) than its automatic calculation.
2:49 – Practical demonstration with a series of images.
* 2:57 – Base TTL shot (0 FEC): The automatic exposure.
* 3:13 – FEC +1: The image is slightly brighter.
* 3:28 – FEC +2: Image gets brighter.
* 3:35 – FEC +3: Image becomes overexposed, showing the range of control.
* 3:52 – FEC -1: Image is darker than the base shot.
* 4:01 – FEC -2 & -3: Progressive darkening, demonstrating negative compensation.
