Abstract: A universal, filter holding apparatus provides an adjustable filter assembly which can hold different size filters. The versatile filter assembly is also constructed and arranged to facilitate tilting, pivoting, and rotation of the filter in different directions and can be guided upon a boom towards or away from a light source, as desired by the photographer. In the preferred form, the filter assembly has symmetrical L-shaped slide members which slide towards or away from each other along the rails of a track to expand or contract the size and span of the filter assembly. The filter assembly can also have a rotatable bracket which can be secured to and rotate the filter. The filter can have an aperture and grommet to facilitate its attachment to the bracket via a fastener. The filter assembly can further be equipped with an articulated tiltable unit which can slide upon and be rotated about the boom to further adjust the position of the filter.
