Which two items help produce good quality enlargements of evidence photographs?

Producing high-quality enlargements of evidence photographs is crucial in crime scene analysis, as these images may be presented in court. The use of a ruler and a parallel film plane plays a significant role in achieving this.

A ruler ensures that there is a known scale in the photograph, allowing for accurate measurements when the images are enlarged. This is important for demonstrating the size and dimensions of evidence in a clear and measurable way. Furthermore, having a parallel film plane means that the camera’s sensor or film is perfectly aligned with the subject being photographed. This alignment minimizes distortion and helps maintain the sharpness and clarity of the image, which are essential for producing high-quality enlargements.

Other choices may provide useful tools or settings, but they do not directly contribute to the overall enhancement of image quality for enlargements in the same manner as the combination of a ruler and a parallel film plane, which directly addresses both scale and focus.
