The softbox is one of the basic tools of lighting--softening, diffusing and directing the light in a controlled way. The Creative Light 1x4' Recessed Front Softbox is 1x4' (30x120 cm) This softbox has an external and an internal diffuser, both attached with touch fasteners. An optional soft grid can be attached to the front, reducing the angle of light to 50°. 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.
