What is an external flash and how does it differ from a built-in flash?
An external flash is a separate unit that can be attached to a camera, typically via a hot shoe or sync cord, to provide additional lighting for photographs. It differs from a built-in flash in several ways. Firstly, an external flash is more powerful than a built-in flash, allowing it to illuminate subjects at a greater distance. Secondly, an external flash can be positioned off-camera, allowing for more creative control over the lighting.
Additionally, an external flash often has more features than a built-in flash, such as adjustable power output, zoom head, and remote triggering. This gives photographers more flexibility and options when it comes to using flash in their photography. Overall, an external flash provides more power, flexibility, and creative control than a built-in flash.
When would I need an external flash?
You would need an external flash in situations where the built-in flash is not sufficient to provide the necessary lighting. For example, if you’re taking photographs in a large room or at a distance from your subject, an external flash would be necessary to provide enough light. Additionally, if you want to create a more professional-looking image with a specific lighting effect, such as a catchlight in the subject’s eyes or a subtle rim of light around the subject’s hair, an external flash would be necessary.
An external flash is also useful in situations where you want to freeze fast-moving subjects or capture action shots. The additional power of an external flash allows for faster shutter speeds, which is essential for capturing sharp images of moving subjects. Furthermore, an external flash can be used to overpower the sun or other bright light sources, allowing you to create a more balanced exposure.
Can I use an external flash indoors?
Yes, an external flash can be used indoors to add depth and dimension to your photographs. When used correctly, an external flash can create a natural-looking lighting effect that enhances the ambiance of the scene. For example, you can use an external flash to illuminate a subject in a dimly lit room, or to add a touch of warmth to a cold and sterile interior.
To use an external flash indoors effectively, it’s essential to understand how to balance the flash output with the ambient light.
