I posted some images in the 60D thread and someone ask for a tutorial. So I decided to make a new thread since I tried to search for old threads, I didn't find this topic. So here it is.
1. material used to produce smoke is an incense stick (kanang gamiton sa mga insik for prayers).
2. any lens will do, but for best results, you may use a macro lens.
3. lighting: in these photos, i used 2 flashes (right and left side of the smoke) with blue and orange gel. it is also ok to use one flash. if you don't have a gel, you may tweak the colors in LR or PS.
4. black background is recommended.
5. i used a study lamp to brighten the tip of the incense stick and also the area where the smoke will be so you can focus easily on the subject since the area (room) should have minimal ambient light.
6. camera settings: ISO 125, 1/200, f9, handheld
7. flash settings: manual @ 1/4 power
8. light up your incense stick and take your shots. minimize any air movement so the smoke will be on one area only. you may blow some air to cause some desired (controlled) movement on the smoke.
9. Post Processing: basic adjustments in LR3. making the background solid black makes the smoke pop out on your image. bring your image to PS (i used CS2). make two layers from the original image and flip one of the layers horizontally or vertically depending on your desired output. merge the 2 layers making some sort of a mirror image of the original photo. then tweak the colors. i used NIK plug ins for the final photos. here are my sample photos.
