You’d be glad to know that doing is a lot less hassle than doing it indoors. Firstly you don’t have to worry about lighting as natural light alleviates a photograph like nothing else. Also, you don’t have to worry about setting up a studio as you are free to choose from the background that you want. It could be in front of a river, a bridge, or a carnival. There are endless possibilities when it comes to doing outdoor fashion photoshoots.
You’re shooting outdoors for a reason – make sure that reason is evident in your shots! A photographer with a good eye should be able to spot elements in the environment that can play well into photographs. For example, use a tunnel of trees to frame your model, or take advantage of reflections on the water’s surface to highlight details in the clothing. If your model is wearing a very long dress, emphasise its length by having her hang (gracefully, of course) off a low branch or ladder. Safety first though!
