In bite mark analysis concern is expressed for the need to improve the precision in photographic evidence collection procedures. The use of a rigid ruler (which meets federal specifications) for scale, proper camera positioning in relation to the scale, and a method to evaluate the distortion in a two-dimensional print that records a three-dimensional object is suggested. Disregarding these factors makes metric bite mark analysis inappropriate.
在咬痕分析中，有人对提高摄影证据收集程序的精度表示关切。建议使用符合联邦规格的刚性尺子作为比例尺，使相机相对于比例尺进行正确定位，并采用一种方法来评估记录三维物体的二维照片中的失真情况。忽视这些因素会使咬痕的计量分析变得不恰当。
