Made for the Indra500 and Indra360 TTL monolights, the Barndoors with Grid and Gel Set from Phottix contains a set of four-way barndoors, a 60-degree honeycomb grid, a set of red, yellow, blue and green gels, plus a carry bag. The grid controls spill and adds directional control to the output. It can be used with the barndoors to further direct which parts of the subject are illuminated. The barndoors can also be used on their own. The colored gels can be used creatively for edge lighting or to light backgrounds.
