The ProFresnel Spot is a huge Fresnel lens that can be mounted directly onto any Profoto head. Being a Fresnel, it creates what you might describe as your typical movie light with a directed, almost horizontal light spread that is perfect for fashion and product photography.
When used at a closer distance, shadows become wider and the light fall-off is reduced. This can be used to create crisp still life pictures, among many other things. Use the optional Barndoors to control its light spread with precision.
