When you start getting serious about documenting your projects, getting lighting correct can make a huge improvement. Like many Tindarians, much of my work takes place in a garage, where lighting isn’t usually a priority. My solution was to put up several clamp lights to illuminate the area. While this generally works well, when you need to get really close to your subject to photograph or record video of small parts, the actual camera can get in the way of your illumination.
To solve this problem for photography, a ring flash is a great option where a series of LEDs forms a ring around your camera’s lens. This eliminates the shadow of the camera since the light source is in front of it. Unfortunately, the portable versions of this type of lighting are generally setup as a camera activated flash, not a continuous light source.
In order for more control over his shooting, Balearic Dynamics’ Enrico Miglino came up with a battery powered LED ring that emits light continuously, and can even be dimmed as needed. While meant for still photography use mounted on a DSLR camera, this type of lighting would also work for closeup videography work, such as showing how components are soldered onto a circuit board.
