Answer:
Q1. Highlight is the lightness of object in graphic design and photography.
Q2. Highlights increase with reflectivity.
Step-by-step explanation:
Question 1:
In photography or graphic design there is an element called 'Value'. Value is defined as lightness or darkness of an object. The value is calibrated on a scale ranging from 1 to 9, from the lightest (1) to the darkest (9).
The value of 1 to 3 on this scale is termed as 'Highlight'. Next three from 4 to 6 are called 'Mid Tones' and the last three (7 to 9) are termed as 'Shadows'. A picture is attached to illustrate this.
Question 2:
The object that has high reflectivity, reflects higher amount of light. Due to this reason the object becomes more brighter and its highlights increase.
