A single 4 by 4 grid containing sixteen portraits of the same person at different stages of life. Each square shows a clear shift in age and physical detail.
Top row: age 1, age 11, age 21, age 31.
Second row: age 41, age 51, age 61, age 71.
Third row: age 81, age 91, age 101, age 111.
Fourth row: age 121, age 131, age 141, age 151.
Maintain consistent facial structure, skin tone, and general features so the viewer recognizes the same individual. Let clothing and background stay simple to keep the focus on aging. Use steady lighting and a neutral backdrop. The style should resemble a clean photographic study with natural expression and clear detail.
