順應智慧型手機及隨身智慧裝置的普及，人人天天滑手機、對美食拍照、分享社群網站，成為儀式般的全民運動，亦是時下最夯的社會景象。本研究主要描繪影像食物戀者，透過拍攝美食上傳分享的行為，在社群媒介下演進的樣貌。 本研究將依據Meyrowitz媒介情境論及布迪厄資本理論，並透過文本分析法，直接以研究對象過去的美食分享文作分析內容，再以深度訪談法結果為依據，並與文本分析的社群內容作比對，瞭解影像食物戀者的行為演進現象觀察。最後以民族誌參與觀察法，實際驗證研究對象在餐廳用餐時的行為動作記錄，並與深度訪談結果作深度觀察交叉分析。 研究發現，影像食物戀者拍照分享的行為可分為兩大階段、六個歷程，包括基礎演進階段的記錄、分享、學習；以及進階階段的炫耀分享、美食意見領袖及形成自媒體。透過社群媒介的展演，影像食物戀者藉由美食圖文故事的包裝，持續依據自身品味資本在社群上傳播，達到提升個人獨特性及品味層次的目的。 關鍵詞：影像食物戀、媒介情境論、自媒體、社群傳播 / Nowadays, corresponding to the widespread of smartphones and mobile devices, the most popular scenes are that people keep on sliding and checking their mobile phones, taking pictures of fine food, and sharing them in social media communities, which has become a viral phenomenon. This research is based on the Medium Theory by Joshua Meyrowitz and Social Capital Theory by Pierre Bourdieu, in order to understand the behavior evolution of “food shooting addicts,” persons who love to take fine food pictures and upload them to social media communities. Its methodologies include content analysis, in-depth interview, and ethnographic participation and observation. The study finds that there are two stages and six phases in the behavior evolution of food shooting addicts. Primary stage includes: record, share and learn. Advanced stage includes: show-off, becoming opinion leaders and “we media” of fine food. Through their presentation in social media, packaged by beautiful fine food pictures and related stories, food shooting addicts build up their taste capital and achieve the goal of raising up their uniqueness and taste.
