This photo is another one from the “scent smoke series” I took not long ago. This time I reversed the colors, to the black background became white and the bluish smoke got some weird brownish color. In Photoshop I was changing that color to a light blue.
Photo data: Pentax K20D, 18-55 mm lens at 55 mm, f5.6, 1/100 second and ISO 400.
