《Negatives: Scans》（底片：掃描）是中國藝術家徐勇繼出版《Negatives》之後，將他於八九民運留存下來的負相系列再度呈現之作。本書皆為前版未收入的影像，並在此新作中保留了底片原本的齒孔，以及因底片掃描所產生的液體痕跡。  1989年，當時35歲的徐勇在北京街頭與天安門廣場拍攝了近代中國最大規模的民主運動，然而由於中共當局的政治禁忌，這批底片從未公開。數十年過去，徐勇決定將這些影像以負片型式發表，並留下了因歲月封存而造成的底片氧化變貌，進一步地展現了攝影的物質性與時間性。  2014年於香港出版的《Negatives》中，徐勇曾指引讀者如果想要觀看正常的顏色，可以打開手機或平板內建的「反相顏色」按鈕，然後開啟相機功能，用照相方式觀看，將書中影像的色彩反轉再現出來。透過這個過程，讀者將發現自己正經歷著影像、歷史與真實之間的關係。  「對中國或世界來說，天安門事件並沒有結束。」徐勇說。在八九民運與六四事件三十年過去，這些底片並未沉默，仍然發人省思。  本書另收錄策展人Gérard A. Goodrow與舒陽的評論文字。  購書請至VOP BOOKSHOP Buy: bookshop.vopmagazine.com  Xu Yong (b. China, 1954; lives and works in Beijing, China) makes art that scrutinizes the photographic medium and its documentary variants and interpretations. An autodidact with a background in advertising, the artist is fascinated by the influence that images have on our collective memories. In 1989, a 35-year-old Xu joined the protesters on Tiananmen Square and used his camera to record the events on celluloid. The publication Negatives: Scans is the second series he presents in the form of unprocessed film. As in the earlier Negatives series, released in 2014, Xu uncovers a censored history, testing the hypothesis that the photographic negative—a preliminary stage on the way to the photograph properly speaking—provides more cogent evidence than analog or digital photography. This focus makes his compilation of documentary pictures an analytical study in the power of images and their ability to shed light on cultural taboos and historical amnesia. With essays by Gérard A.
