24x36 Black Single Scrim Open End Frames are made of spring steel with a 3/8" pin and support which can be used to hang the Scrim from a C Stand handle when not in use. The two upright arms of the frame are slotted at the two open ends to retain the piano wire woven through the fabric to make up the fourth side of the frame without causing a shadow.
Open Ends are used to control or manipulate light falling on certain areas of the set or subject. They can be used to soften or reduce light without a noticeable edge. A color coded binding is used around the frame to identify the fabric. Matthews Open End Frames are black powder coated to minimize unwanted reflections.
Black Bobinett in it single form will reduce light intensity without changing the color temperature of your shoot, with twice that as a double.
In order to ensure that lighting characteristics are consistent from one year to the next, Matthews Studio Equipment, Inc. always purchases fabrics from the same supplier - not the cheapest...
You can be certain that the light transmission and reflectance values of the sewing products offered by Mathews will be the same from lot to lot, month to month and year to year.
