ABFO No. 2 Photomacrographic Scale

MODEL: 6-3875 SKU: PART:

Designed by the American Board of Forensic Odontology (ABFO), this scale has become the standard for bitemark measurement and photography. The incorporation of three circles is useful in helping to compensate for distortion resulting from oblique camera angles. Graduations are all metric except for the width of the legs, which are 1" wide. The 1cm division lines are traced and extended across the photographic print to grid an image. Measurements within the image are then made relative to these inscribed 1cm grid lines to compensate for any distortion resulting from nonparallelism between the film and the object planes.

ABFO No. 2 Photomacrographic Scale is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from not for curved surfaces Nice little tool and I use it often. The rigidity is great for flat surfaces but not so much for curved ones. We take photos of inside pipeline and it does not always bend to the shape of the pipe so therefore creates unwanted shadows. Maybe its my photo skills but the camera always wants to focus on the ruler and not the actual pipe sample.
