The softbox is one of the basic tools of lighting--softening, diffusing and directing the light in a controlled way. The Creative Light 1.3x2' Flat Front Softbox is 1.3x2' (40x60 cm). The size and shape of the subject dictates the size and shape of the softbox you use for a main light--smaller softboxes for smaller subjects, larger ones for larger subjects. The softbox can also be used as a fill light or an accent light. All-steel support rods are included. Dedicated speedrings for most popular brands of flash head are available separately.
