With just one or two electronic flash devices, interesting multiple exposures can be created. In addition to being aesthetic and fascinating, multiple exposure photos are frequently used to research subject motion and position. Even the smallest amount of action may add interest to most images. However, due to the brief duration of light from electronic flash, it is perfect for photographing any activity, from a fleeting smile to a sporting victory. Each sort of action requires a distinct camera approach. Most electronic flash units have a maximum flash duration (the length of time the light is on) of roughly 1/800th second, and a minimum flash duration as low as 1/20000th second, therefore you may freeze practically any activity with the flash. If done improperly, flash photography during the night outdoors might result in highly underexposed pictures. Flash does not travel very far outside, making it challenging to illuminate objects from a distance, but this constrained range also provides you excellent control. A portion of a flash’s power indoors is reflected back to the subject by the walls and ceiling. Some light is lost because such reflective surfaces are hardly found outside. When taking pictures of objects at any distance, you must widen your aperture to make up for the light that was lost. Opening up your aperture by two or three f/stops may not be unusual because so much light is absorbed in these substantial areas. Before filming in a large, indoor space, tests should be done. It is crucial that you put the fundamental ideas you now understand about photo graphic techniques into practice. You are constantly exposed to different composition and lighting styles whether you read a book, magazine, or newspaper, watch TV, or go to the movies. Every time you glance through a camera’s viewfinder, learn them and put them into practice. Always play around with different camera perspectives to produce intriguing views on your subject of interest. Consider the effects that the direction, intensity, and type of light have on your final work whether employing flash or available light. The effectiveness and aesthetic value of your photography can be significantly improved by persistently using and honing the principles of composition and lighting. t night a single on-camera flash produces stark lighting, and your subject is flatly lit and the background goes completely black. Close details become very overexposed, and it is better to exclude them. Such simple lighting is ideal for action shots; for example, capturing leaping karate experts in midair at midnight. Subjects such as these benefit by being isolated from the background, but you may get more interesting lighting by using the unit off camera on an extension cord.
