Using a flash can help maintain a good exposure of both the model and the background and give that extra punch to your outpoor portrait. A low winter sun as rim light can also create some extra dimension to the image. Here are photographer Hannah Couzens' tips for mixing ambient light with flash.
Step 1: Set the exposure in your camera for the background.
Step 2: Place and angle your Profoto A1X and a Umbrella Deep White to find the perfect position for your model and the light pattern you want to achieve.
Step 3: Turn on the flash and now set the exposure for the model.
In order to avoid the image looking too artificial or flashy, choose a large modifier relative to the subject. This will produce a softer light quality to match the natural conditions of the environment.
