A parabolic softbox is a light modifier whose main purpose is to soften and more accurately direct the light from a flash or permanent light source. It differs from conventional softboxes by its specific, deep shape, which is based on the geometry of a parabola, similar to that of a satellite dish. This design allows the photographer to change the character of the light by moving the light source inside the softbox. When the light source is placed at the focus of the dish, i.e. near the back, the softbox produces a focused, contrasted and directed beam of light with a more pronounced transition between the illuminated area and the shadow. This light is often described as "crisper". Conversely, when the light source is moved towards the outer edge of the softbox, the light diffuses over a wider area, becoming very soft, even and enveloping, similar to a large traditional softbox. With this ability to change the character of the light from one extreme to the other, the parabolic softbox provides a high degree of control and versatility for creative lighting, especially in portrait and fashion photography.
