Photography: Get the best out of the built in Flash

1. Get In Close

The main limitation of built in flash units is their power. Whereas external flash units have their own dedicated power source and can be quite large - a built in flash shares it’s power with your camera’s other components and it’s generally quite a bit smaller.

Knowing this should drive you to get in close enough to your subject for the flash to have some impact (usually within 2-3 meters). If you can’t get in close (for example if you’re at a rock concert and are sitting in the back row) you’ll probably achieve better results by turning your flash off and bumping up the ISO setting.

2. Try Slow Sync Flash

Another limitation with in built flash units is that they can produce quite harsh results that mean any other ambient light in a scene is lost. This is partly because the light they produce is unable to be directed/bounced indirectly onto your subject.

One way around this is to use Slow Sync Flash. You can read about this technique in our tutorial on the topic - but in short it involves choosing a slower shutter speed and firing the flash while the shutter is open.

3. Diffuse or Direct Your Flash DIY style

I’ve already alluded to the problem of not being able to diffuse the light produced by a fixed flash unit - however one technique that some inventive photographers use is to take a Do It Yourself approach and create their own diffusers.

Some photographers I know always have a roll of semi-opaque adhesive tape in their camera bag to put over their flash. This doesn’t stop the flash’s light but diffuses it.

Other friends take a little piece of white card with them which they put in front of their flash to bounce it up or sideways.

Using these techniques might mean you need to play with exposure compensation (you’ll probably want to increase exposure by a stop or two) as your camera won’t be aware that you’re taking some of the power out of it’s light.

4. Fill-in Flash

Don’t just use your flash when it’s dark. Often when shooting outdoors a flash can really lift an image up a notch - particularly when photographing a subject with strong backlighting or one with harsh downward light. A fill in flash lights up shadowy areas. Read more about Fill Flash.
