Use a White Ball As a DIY Flash Diffuser for Portraits
Taking photos using your camera’s built-in flash can result in harsh lighting of unflattering photos, but if you’re in a dark place, you need something to light up your subject. Try using the white ball as a pocket flash diffuser that can be used in seconds.
As the name suggests, a flash diffuser takes the bright “spark” of a camera flash and spreads it over a wider area, like a lampshade. This will make your subject appear more evenly lit instead of looking like a spotlight is shining on it.In this video from the Kuldonov Brothers, we see how a white balloon can serve as a diffuser in a pinch. (You can buy a real attachment that fits over your camera’s flash, but this is usually for flash attachments, and it’s also an optional kit that you can carry with you.) I have experimented from time to time with holding plain white paper over the camera flash, and in fact you can try any white translucent surface. The white ball, on the other hand, is surprisingly effective.
