Final answer:
Depending upon the artwork in question, the element or principle of art could be emphasis, contrast, or a distinctive use of color such as secondary colors. Factors like focal points and color wheel compositions (primary, secondary, tertiary) are critical in analyzing artwork.
Step-by-step explanation:
An element of art or principle of design that is prominent in a photo could be a variety of options, depending upon the composition and techniques used in the photo. Emphasis can be seen as a color, unity, balance, or other principle or element of art used to create a focal point in the artwork. For example, the use of contrast with a string of gold in a field of dark purple would cause the gold lettering to pop out, serving as the focal point. Considering color, the modern color wheel includes primary colors (red, yellow, blue), secondary colors (orange, green, purple), and tertiary colors. If the photo includes prominent use of orange, green, and purple, it would be centered around the concept of secondary colors. Finally, the integration of the elements and principles of art helps organize sensorially pleasing works of art, contributing to its overall aesthetic appeal and composition.
