BullsEye Camera-Alignment Mirror

       The BullsEye provides a quick way to avoid getting a keystoned image, when photographing flat artwork.

 

       The typical approach for squaring the camera with the art work is time consuming, taking measurements, using a carpenter’s square, T-square, etc.  Simply centering the object in the camera’s viewfinder does not guarantee a rectilinear image.  With the BullsEye, it is not necessary to know any dimensions or the angle of the painting to photograph it as a rectangle.

      The BullsEye™ is the shape of a hollow spool.  A mirror is attached at one end, facing inward.  A curved wire handle loosely holds the device by side holes at its center of gravity.  A strap attached to the wire handle, holds the BullsEye™ from above.  The pressure against the artwork is a small fraction of the weight of the BullsEye™.  A felt backing on the mirror prevents damage to the painting.
