How is a background light used to separate the subject from the background? What is the palette? How tight is the framing? What is the angle of view?
Lighting Pattern: Flat light
How much fill is used to brighten the shadows? The fill is used to help neutralize the picture instead of brightening it. Since the background has a lot going on there are no shadows.
How is a background light used to separate the subject from the background? The background light is only evident in the first example where you can see that the model’s hair is backlit other than that the background in other pictures is natural light.
How tight is the framing? The framing is pretty open the pictures have been taken from a further angle where you can see the almost upper half of the body.
What is the angle of view? The angle of view is mostly eye level.
You are right about flat light. Note that one is shot at night, one on a cloudy day and one on a sunny day but all have very soft light on the model’s face.
