A collapsible light modifier includes a plurality of rods mutually interconnectable one after the other between a first terminal portion and an opposite second terminal portion to form a frame of the light modifier and which can be mutually disconnected to disassemble the frame, and a fabric connected to the frame. Each rod is bound to at least one adjacent rod by a binding element provided between each pair of adjacent rods so as to keep the rods bound to each other when the frame is assembled and when the frame is disassembled, and, both the said first and second terminal portion includes a first end, connected to a respective rod, and an opposite second free end. When the plurality of rods is mutually interconnected, the respective second ends of the first and the second terminal portion can be connected to each other in order to form a closed frame.
