There are 4 types of softboxes: square, rectangular, octagonal and striplights. Each has a different utility. The square softboxes are ideal for portraits and nature. The rectangular softboxes are useful when wanting a source of constant light from head to toe of a person. The octagonal softboxes / octaboxes reproduce the effects of umbrellas, whereas the striplights allow narrow lighting for a ‘spotlight’ look. The main advantage of softboxes is that, they produce very soft shadows, almost to non-existent. You will also find beauty dishes of various compatibilities (Bowens, Broncolor and etc) and sizes.
