The YE083 is designed for the evaluation of the halftone reproduction of an electronic camera. Two 11-graduated counter current gray scales are arranged on a gray background(D=0.62) . The gray scales being graduated logarithmically (gamma = 0.45).The output signal of an optimal gamma-corrected camera yields two 11-graduated counter current linear step signals. The contrast range of the gray scale is 40:1.

The values of the 11-graduated gray scale are as follows:

Step Density Reflectance in %
1 0.05 89
2 0.13 74
3 0.22 60
4 0.32 48
5 0.43 37
6 0.55 28
7 0.69 20
8 0.86 14
9 1.06 9
10 1.31 5
11 1.65 2

The density of the white field between the gray scale is D=0.05 (reflectance = 89%).

FAQs About  Grayscale Charts

In the study of chemical reactions, calorimetry deals with changes in heat (energy and enthalpy). Spectrophotometry is the measurement of the light absorbance or light transmittance to determine the concentration or color of a solution. The first one monitors the thermal processes, whereas the second one addresses the aspects of light and color.


The concentration of colored compounds in a solution is determined by the use of a colorimeter test. It can be used to measure the quality of the product. The colorimeter test determines the presence of contamination or observes chemical reactions by measuring the extent to which a solution absorbs light at a given wavelength.


The accuracy of colors is determined by comparing the values of the colors (L*a*b*) of a sample with a standard reference sample using tools such as spectrophotometers. The variation is measured as ΔE. The smaller the value of ΔE, the more accurate, the nearer to the target color.


To take care of a haze meter to make it last longer, ensure that it is cleaned, recalibrated regularly, and stored in a dry, dust-free place. 


Depending on the scale of the manufacturer, its matte, low-sheen finish can be called gloss level 3. Overall, gloss levels in certain standards go between 1 (flat) to 7 (high gloss). Level 3 is considered low-gloss or satin-like.


A spectrophotometer and colorimeter are certain instruments used by scientists to measure color by quantifying reflected or transmitted light. The results are presented in color spaces, such as L*a*b*, RGB, or XYZ. This enables the accuracy of comparison and tracking of the changes in color in chemical or material research.
