@30pics4jackiesdiamond extremely easy. All you need is a room where the sun comes in . I used two pieces of black poster board but anything black will work, to block off the space and give a clear bg. I stick the incense in a candle for easy moving. You need to play with it a bit to figure out exactly where you want the light to hit, but the process is lots of fun. I find the actual sunlight gives the best results. I lower my brightness to tone down the excess and give a deeper black.
@30pics4jackiesdiamond PS. Take a lot of shots. Take them up close. Take them far back. Take them turning the camera. You just never know what will come out.
