How to use fill flash
In one of my posts I had given a brief idea on fill flash and when to use it. Before reading on, I would recommend you to read
In this post, I am going to illustrate this technique. This is completely different from Full flash – which is used during night and very low light situations. In full flash photography, the main light source is flash itself. While in fill flash photography, the flash is used to fill the shadows.
How to use fill flash? — Fill Flash Photography
The above picture of sunflower is a high dynamic range scene. This photo is taken by exposing for the background. As a result, the foreground subject — the sunflower — becomes dark. If one exposes for the sunflower, then the background will be over-exposed. So, [one of] the solutions for getting a proper exposure is make a double exposure. i.e.
- Use flash to light up the flower/fill the shadow areas with your flash — Exposure #1
- Properly expose for the background — Exposure #2
So I used my external flash on low power and filled the shadows on the flower with the flash light. And here is the result:
As you can see, now the image is properly exposed — both for the background and for the foreground. Here, I fired my external flash from the left side of the camera to properly fill shadows. So you have to target the light to the shadows areas. You will find it very useful while taking portraits.
From this example, I hope you have got an idea about how to use a fill flash. If you have any queries, drop them as comments.
