Proper lighting is a staple of good photography and videography. Whether you're a beginner, enthusiast or professional, flashes and on-camera lights should be integral tools in your work. Flashguns have the ability to illuminate objects, create special effects, and set a certain mood.
What's an On-Camera Flash?
An on-camera flash or flashgun is a piece of equipment that produces a beam of light for a very short period of time when you release the camera shutter. You can use it to lighten shadows and to brighten your subject without having to decrease the shutter speed or increase the ISO settings. External camera flash accessories out perform internal camera flashes because they're more powerful and thus can be used at greater distances. They can also be pointed in many directions for greater artistic control, and can even be used to creatively to produce unique effects. Additionally, external flashes have an internal flash battery instead of running off your camera's battery, allowing you to take more photos.
Types of Camera Flashguns
There are various types of camera flashes available. Regular, on-camera flashguns often have a rectangular-shaped light that can be directed straight or moved vertically and horizontally. You can use on-flash light modifiers, such as soft boxes and dome diffusers, to soften and disperse the light. Macro and ring lights fit around the camera lens to illuminate objects at short distance. Ring lights are popular in; portrait photography, macro photography, interviews and vlogging because they deliver even, diffused light that eliminates hard shadows. They also create a distinct circular reflection in the pupil of your subject's eyes. Battery-powered heads are a type of flashgun that can be used on and off the camera. They have an incredibly quick recycling time, and you can combine them with a great range of light shaping tools.
Flashguns are designed specifically to a particular brand of camera.
