Tendrils of smoke and dye drops in water have a similar elegant appearance, beautiful for abstract photography. Both are unpredictable, however, so you’ll time for trial and error while shooting. For smoke, you’re best off using a black background and incense instead of matches, as incense will burn for longer. For dye in water, you’ll need a white background, some food coloring, and a clear glass container with straight sides, like an aquarium or square vase.
