The Octobox creates a different approach to your lighting. The Octobox is the perfect answer for portrait or fashion work as the light delivered from the eight sided box wraps around the subject to produce an even spread of light. The external diffuser softens skin tones whilst the internal baffles eliminates hotspots & specular highlights & produces an even head to toe illumination of the subject. Maximum Light loss=1 stop with both baffles inserted. Produces an excellent " Catch light" in the eye. & can be used successfully with the Interfit Portrait reflector kit to create a simple but highly effective " Butterfly Lighting". To fit a softbox to a head you will need to know the fitting type. If it is an intermit head it is likely to be the ASA1000 ring (S Type Fitting).
