A device for controlling projected light beam from an electronic flash,
this invention consists of a tube of elastic material such as neoprene or
polyurethane (4), with a light side (6) and a dark side (5). The shape
and elasticity of this device allow its configuration to change by
rolling the snoot over on itself. Rolling the snoot partially upon
itself, changing its length, will thereby change the size of the
projected light beam. Rolling the snoot inside out will select a
different interior reflectivity, thus a different quality of projected
light.
