In the research article, we focus on research and data collection from the perspective of the child, where the latter is an active researcher. During the research, we sought to break the scientific effect of data collection, which can only be done through play and by including all children in research, or so-called experimentation. We offered them resources that encouraged a high level of motivation, and we guided the children through the research with open-ended questions. Qualitative research is presented with an emphasis on interview techniques. In the theoretical part of the article, we focus primarily on photography, which is a very common visual method in research with preschool children. Namely, it is one of the methods that encourages children to discuss, think and discover the unknown. We present the advantages of photography as a widespread method and the challenges we face when researching with younger children. In the empirical part of the research, a small sample of children (N = 9) was interviewed with a photograph taken by the child, and the purpose was based on the analysis of the child's perception and interpretation. The central theme refers to the child's experience of positive feelings expressed through the photograph. A descriptive causal non-experimental method of empirical pedagogical research was used.
