Crime Scene Photomacrographic Scale No.2 Metric

The Crime Scene Photomacrographic Scale (No.2‑Metric) is an L‑shaped, 105×105mm laminated plastic scale with 1mm thickness that provides precise millimeter measurement and tonal reference for forensic close‑up photography.

When documenting small evidence, consistent size and reflectance references are vital. This compact, rigid photomacrographic scale combines fine metric graduations, high‑contrast 1 cm alternating bars, and a neutral gray patch to help photographers and investigators capture images that support accurate measurement and better visual comparison in reports and court exhibits.

How accurate and durable is this photomacrographic scale?

The scale is made from a rigid, 1 mm laminated plastic designed to resist bending and hold its printed markings under repeated field use. Millimeter markings are produced to an accuracy of 0.1 mm or better, so measurements taken from photos remain trustworthy when photographed at appropriate angles.

• Rigid L‑shaped construction resists flexing during placement
• 1 mm thickness for stable, repeatable positioning
• Millimeter markings accurate to 0.1 mm or better
• Durable lamination protects printed graduations from wear

Can it be used with challenging exposure or lighting conditions?

Yes — the alternating black and white 1 cm bars provide clear high‑contrast reference even in overexposed or underexposed images, helping digital processing and human review. A neutral gray area with roughly 18% reflectance offers a consistent tonal reference to assist white balance checks and visual comparison.

• Alternating 1 cm black/white bars for contrast in extreme exposures
• Approx. 18% gray patch for tonal and reflectance reference
• Useful for white balance checks and post‑processing normalization

How large is the scale and how do I position it for macro photography?

The overall L‑shape spans 105 mm by 105 mm, making it compact enough for close quarters while still showing a clear scale in frame. Position the long arm of the L parallel to the plane of the evidence and keep the camera axis as perpendicular as possible to the surface to reduce parallax errors.

• Overall footprint: 105 mm × 105 mm for tight scenes
• L shape allows edge alignment against objects and surfaces
• Place flush with the subject and keep camera angle perpendicular to minimize distortion

What materials and markings should I expect on this forensic scale?

The scale is printed and laminated on a stable plastic substrate with crisp millimeter graduations and contrasting bars. Gray printed areas have been specified to a reflectance near 18% to provide a predictable visual reference under photographic lighting.

• 1 mm thick laminated plastic stock for longevity
• Fine millimeter graduations with verified accuracy
• High‑contrast black/white centimeter bars and neutral gray patch

Who is this for? This Crime Scene Photomacrographic Scale (No.2‑Metric) is built for crime scene technicians, forensic photographers, laboratory personnel, and anyone who needs a compact, accurate measurement and tonal reference for close‑range photography. Its small footprint and precise markings make it useful in tight field conditions, evidence trays, and microscopy setups where consistent, reproducible photographic documentation is required.
