With centimeter scale as the basic unit of measurement, the scale with the same subject photographed recorded, according to a scale to measure the original size
Its characteristics; prevent deformation, restitution of a shooting method.
Method 3 rule
3.1 Measurement of smaller exhibits, traces should be selected as the minimum measurement unit to mm-scale black and white, color scale and transparent scale,
The error rate can not exceed one per cent of its edges shall be legible scale.
3.2 Measurement larger exhibits, traces of tape should be used. Common are steel tape and leather tape measure, generally in cm measuring scale unit length
More than 2m.
3.3 before the shooting, would not reflective, crease-free flat scale, the subject is placed on one side of the body, pointing to the side of the scale subject. Take
When taken, the camera lens and the subject and should be kept vertical scale, the scale should be subject at the same focal plane.
3.4 When shooting lateral object, the scale should be placed below the subject, and the screen is proportional to the lateral placement; shooting longitudinal object scale should
Placed on one side of the subject, and the screen is proportional to the longitudinal placement.
3.5 black and white photography, as the subject is dark tone, choose black white stripe substrate dimensions; as a subject light colors, use white
