Photographers use the phrase “available lighting” when talking about how a picture was made using whatever illumination was there at the time. Using available light usually leads to a quicker, more fluid way of working than, say, setting up in a studio full of lamps, or rigging portable lights on location.
When I teach lighting, I prefer to talk about light sources. A source of light can come from a window, or a cloudy sky, or a bare bulb hanging from a ceiling. I wrote about on-camera flash recently, a light source I use as only as a last resort.
If you look around you carefully, you’ll begin to recognise many kinds of light sources. Using available light creatively can be fun, as it was for this informal portrait.
Ruby was one of many people at a family gathering on Christmas Day. She was intent on grappling with some badly behaved software, when I noticed her striking hair style. Although the room lights were on, it was the glow from the bright screen in front of her which caught my imagination. Turning off the overhead lights and turning up the ISO speed on my point-and-shoot to 800 allowed me to use the computer screen as an available light source, at the same time throwing the background walls and furniture into darkness. I removed the colour afterwards, preferring this monochrome version.
If you’d like to try this approach, but don’t know how to change the ISO speed on your camera, look for a “night scene” setting instead. Or keep it on “Auto” and remember to switch off the flash. If that’s not easy, and menus can be a pain, simply block it off with a spare finger.
