Softbox
Light
A modifier for studio or flash lights that diffuses light into a large, soft source.
The larger the softbox, the softer the light. A 60×90 cm softbox is softer than a 40×40 cm one. Placing it closer to the subject makes the light even softer. Square and rectangular softboxes are versatile for portrait; octaboxes (eight sides) give a more circular catchlight.
