An Exploratory Study on Ephemeral Photo-sharing of Korean Smartphone Users ; 스마트폰 휘발성사진 행태연구 :모바일 사용자의 휘발성사진 이용행태와 내용분석을 중심으로

학위논문 (석사)-- 서울대학교 대학원 : 융합과학기술대학원 융합과학부, 2018. 2. 이중식. ; With the prevalence use of smartphones, the practice and culture of taking photos and sharing them have dramatically changed. Todays users take digital photos using their smartphones and share them via diverse social media platforms. As this digital photo culture has matured, a new phenomenon of taking photos to share for a limited duration (e.g., 24 hours) has emerged. An introduction of ephemeral photos reshaped how people express themselves, live in the moment, and have fun together. The practice surrounding ephemeral photos has gained popularity and many social media platforms such as Snapchat and Instagram have introduced new functions supporting this practice. While previous studies provide sufficient evidence for ephemeral photography and traits of ephemerality, they lack an empirical approach with more quantitative analysis. The majority of studies were conducted based on the memory retrieval method, which is known to pose several limitations regarding participants untruthfulness and lack of retrospective ability. In order to overcome these issues, the current study uses a research-specific Instagram account for content analysis to obtain raw data of users photo sharing behavior. Data were gathered using mixed method approach: Photo Elicitation Interview (PEI) followed by ephemeral photo log data collection with semi- structured interviews. Among the research participants, 14 people participated in the interview, where a total of 37 participants ephemeral photos were collected. In order to understand what is captured (content) and its sharing strategy, this study observed a total of 14 participants in three different studies. The findings of this study explain characteristics of both ephemeral photo and non-ephemeral photos and understand user strategy of taking and sharing ephemeral photos. The study reveals that the content of ephemeral photos heavily relies on not only on editing formality, but also pertinence, timeliness, process-ability ...
