Lighting for photography and video
As a rule, there are three main types of light for photographers. Studio flash normally means either a self-contained unit known as a monobloc, or a flash head with a separate power pack that’s connected via a cable. These flashes are mainly used in studios where there is a mains AC power supply and semi-permanent or permanent set-ups. The flashes can vary in power from 125Ws to as much as 3200Ws from some studio power pack units. Some have flash durations as short as 1/80,000th second which can be used to freeze motion. Power-pack based units have the advantage of taking weight away from the top of a light stand. This is especially important when using larger light shapers.
Speedlites and portable battery flash are probably the most popular form of lighting for photographers. The flash and battery technology has evolved leaps and bounds over the last ten years. Lithium Ion (Li-ion) batteries have replaced lead gel cells and flash sync speeds now exceed the camera ‘standard’ of around 1/200sec with the advent of HS and HSS High Speed Sync technology. Portable battery flashes range in power from 60Ws to 1200Ws.
LEDs are compatible with any brand of camera or smartphone. There are many advantages over traditional hot lights and fluorescent lights. Continuous lighting is WYSIWYG (What You See Is What You Get) and most of the time the camera will handle exposure metering. LEDs have a much longer expected working life in excess of 10,000 hours and are energy efficient.
