There’s a clump of these wonderful gladiolas that grow in my garden this time of year. I cut this stem, and photographed it in a dark room on black. The only light source was an LED headlamp that I used to “paint” with light to illuminate the flower. The trick with this kind of light painting is to never linger too long on any one spot.
