What is off- camera flash and why should you use it?
Off- camera flash means that you are using either one or more external flashes to provide light to the scene, and your camera will be interconnecting with these flashes via some remote method either wireless or a hard- wired link. Beyond this, there are two distinct ways of determining how to expose accurately using flash i.e. the TTL (Through- the – lens) and the manual flash. TTL is analogous to the way a camera works out its spontaneous exposure information.
On the other hand, manual leaves all the settings up to the photographer and has no automatic interface that determines the exposure settings. Working with the off- camera flash requires one to be equipped with several techniques that would enable him or her to operate efficiently. Professional photographers such as this essex wedding photographer who have used the off- camera flash have liked it, and they also recommend to others.
What are the reasons for using off- camera flash
Off- camera flash creates fascinating shadows which translate into interesting pictures. It is poised that to generate interesting photos you require an unusual light. And to create interesting light, you need exciting shadows. These shadows can be set up by just moving the flash off- camera. Unlike on- camera flash which produces coarse light that draws flat and shapeless subjects with harsh highlights and black shadows, off- camera flash conveys dimension, shape, and mood via the interplay of shadow and highlight.
Off- camera flash also allows for full Through- the- lens (TTL) exposure control. This, therefore, allows for automatic exposure information of the camera as the camera has a spontaneous interface that determines the exposure settings.
Working with an off- camera flash system is one of the most important techniques of lighting multiple scenes. The use of ambient light as the primary source is often preferable but in situations such as a wedding, time is usually a limiting factor and the photographer has to know how to expose all the varying scenes using both artificial and natural sources of light. Being resourceful with your lighting setups offers greater efficiency and having a lighting system that can be moved easily from one situation to another as quickly and efficiently as possible is vital. It is for this reason that that off- camera flash system comes in.
This system can be set in a modular manner to fit best the spontaneous nature of a wedding. Multiple flashes can be used in this system thereby guaranteeing creative possibilities and freedom by not having to relegate the flash to the top of the camera. This enables the photographer to be in control of how the lighting system is placed, and also he or she can manipulate the lighting system which puts him or her in control of how the resultant image appears.
When building an off- camera lighting setup requires you to put into consideration the kind of environment you will be operating in and also pre- visualize the light you would like to attain. The key goal of shooting a wedding is to be s unobtrusive as possible. Therefore, working with an off- camera flash is a guaranteed method to accomplish refined lighting in a low- profile manner.
