摘要 A camera attachment adapted to be mounted about the lens of a camera comprising a hollow tubular or conical device having a plurality of concentrically or coaxially disposed rings or annular elements. Each ring comprises a plurality of colored sectional pieces or segments. All of the ring segments are fabricated from differently colored translucent materials and the segments of any ring may comprise equally sized angular segments or unequally sized angular segments. The device may comprise, for example, a plurality of rings forming a hood-like device having semi-circular segments or rings having more than two 180 DEG segments, such as 90 DEG , 120 DEG , 30 DEG , 5 DEG or any other angular segment. With such a device, a plurality of randomly or uniformly spaced angular segments forming a multi-colored band of concentric rings may be formed about an image filmed with a camera having the device mounted about its lens.
