smoke Imagined. After repeatedly watching YouTube instructional videos to learn to use my new flash and trigger, I explored some YouTube smoke "how to's”. Fun. I’ll have many more sources of smoke (other than match sticks) to explore but flash created an errie reflection on this picture. Nikon D3400, M: ISO100, f14, 1/200th sec, 30mm with 18-55mm lens. Flash pointed through the smoke. LR adjustments of temp, tint, white and exposure. Some crop.
