After reading this article; www.photopoly.net/smoke-photography-made -easy/ I tried these smoke shots. I don't like incense so I kept lighting and blowing out a small votive candle. My first attempts didn't turn out well so I reread the article and realized my aperture wasn't set correctly so I tried a few more shots and was happy with these results. Learning how to add the gradient fill layer in Photoshop was a new skill for me. It felt great to learn something new today!
This shot is cropped but no special Photoshop effects:
