Adding a bit of motion to a portrait can completely change it, making it a dynamic image that encourages the viewer to look more closely and imagine what story it is trying to tell. One way to add motion is to introduce a breeze, and this great video tutorial will show you three ways to do that as well as how to work with the results.
Coming to you from Gavin Hoey with Adorama TV, this excellent video tutorial will show you three different ways to use a breeze to add a bit of motion to a photo. I generally prefer a wafting board for this. It requires an assistant, which can make it unusable if you work alone. However, they can be preferable simply because they only produce a breeze for the actual shot. The more time a subject has to spend in a breeze, the more likely their hair is to start to tangle and become difficult for them, so only introducing it for the shot can help to mitigate that issue. As Hoey mentions, be patient. It's an inherently unpredictable process, so it may take a lot of attempts to get the shot you want. Check out the video above for the full rundown from Hoey.
