Another flash tip for you today.
Say you are using a flash for a portrait outdoors. You want to decrease the ambient light, of course, and add flash to light your subject. But uh oh – you run out of enough power. You verify this with the full-power tip I gave you the other day. Not enough.
One option: concentrate the light more.
Your flash includes a zoom mechanism, to ensure the light goes as wide of the lens. If you have insufficient power, you can:
- go to manual flash zoom (press buttons on the back of the flash for this)
- zoom in to a longer setting then your lens (e.g. 100mm when in fact you are using a 35mm lens).
Drawback: only the centre of where the flash aims is now lit – so, aim carefully. The big benefit, however: the light is concentrated more, and hence brighter. You get more power when you need it!
