The beauty dish is the most commonly used light modifier in fashion photography, and adding in flags and reflectors makes it even more versatile.

The beauty box is a great technique for using with a beauty dish, it's not as soft as a softbox and not as harsh as a silver dish. Grids give you more control in the falloff of the light.

The silver dish is a very contrasty and dramatic light that comes in a variety of shapes and sizes.

The ability to work with different light modifiers, from ring lights to black light, can help you stand out from the crowd.

A second light can be used to help separate the subject from the background.

Another use for a second light is to illuminate your subject with both lights from the front.

A focus on shape or color can be achieved by shooting the subject in silhouette or by gelling your lights to emphasize different colors.

Adding a second light can be used for more than just separating the subject from the background, while adding a third light gives you even more control.

Using more lights can give you a lot more creative freedom.
