The cultural events of Qajar historical period in Iran are intermingled with the art of photography. The remaining photographs, from this Qajar period, are a narrative of the life of Iranians in that period of history. In these photos, mostly adults are depicted; But sometimes the image of children has been recorded as the subject of photography. The main question in these remaining photos is, what components were influential in the beauty of children's self-decoration in the photos of the Qajar era? In this study, with a qualitative method and using the analytical-descriptive method and benefiting from the theories of native aesthetics, more than 154 pieces of photos from the collection of photos of the book have been examined. The findings indicate that the native aesthetics of children's self-decoration in photos is influenced by the changes in the structure of Iranian society during the Qajar era, and the "desired body shape of the era" is related to the two components of traditional and modern beauty, children are rarely showing their true states, meaning "I am free". According to power and wealth, they try to display their distinctions with pride towards other society and adapt themselves to the advanced idealism of the "Western other", but the look and body shape of children in front of the camera as a government tool or alien. It indicates that they are worried about their judgment and children were like small adults in decorating and living.
