| 摘要: | 電影視覺色彩風格的調性（Tonality）長久以來都是一部電影給人第一印象的關鍵，其色彩應用包括了營造氣氛或是傳達意念等等。以往，精確的色彩調控流程只會出現在高階電影的製作，但隨著微電影的普及，更高的製作規格也開始投入了微電影的後製流程，因此專業的色彩調校技術已不再是好萊塢電影的專利。但目前市面上調色剪輯軟體眾多，專業調色人員的素質也參差不齊，因此如何自前製到後製的創作過程中，發掘出一套可以對電影的視覺色彩風格快速定調的工作流程十分重要。人對色彩或是對於色彩組合所產生的感覺便是所謂的色彩意象，其相關研究也在 40 年以前已經開始，而國內已有學者對電影的用色做了概括性的研究。本研究試圖探討不同色調之微電影是否會在人們心理上產生不同的感受？如果有不同，其影響是否有共通的趨勢？其研究目的在結合電影調色與觀者色彩語意空間之心理感受，擬定一套可依循的專業調色與後製工作流程。本研究以三種不同情境之影片作對照，分別以正向情緒（開心、溫馨）、負面情緒（悲傷、孤獨）與中性情緒進行色相、彩度之調整。實驗根據受測者作答由八對兩極化的形容詞，分別為：喜歡-不喜歡（Like-Dislike）、醜陋-美麗（Ugly-Beautiful）、溫暖-冰冷（Cool-Warm）、柔和-剛硬（Soft-Hard）、優雅-低俗 （Elegant-Vulgar）、花俏-保守（Loud-Discreet）、女性化-男性化 （Feminine-Masculine）、 愉悅-不愉悅 （Pleasant-Unpleasant）共計8 組語意詞組之色彩意象調查。以語意量表建立色彩意象模型，藉此分析歸納出電影用色的一些準則與調色的方法。其中以中性情緒之影片作為主要觀察對象，使用電影級攝影機Blackmagic Cinema Camera的Cinema DNG RAW格式進行拍攝，並在調色處裡時以DaVinci Resolve進行處裡，結合色彩度量的方法在電影後製的調色處理上有更進一步的分析與探討。
The color tone can be a crucial impression in a movie. In the past, accurate color tuning process for color tone adjustment is deployed only in the high-end film production. As micro film production is gaining popularity, more high-end color tuning processes are also used in the post-production process of micro films. Therefore, the professional color adjustment technique is no longer limited to Hollywood-type high-end movie production. However, there are many kinds of color tuning software on the market. How the professional colorists operate the software to tune the color is also lack of a standard reference. How to determine a good workflow from pre-production to post-production in adjusting color of the film is a topic deserved further study.
This study combines color measurement and color adjustment technique on the film production. Three film clips are used to generate the test objects for 138 observers to review and report the color impression. A semantic differential scale consist of 8 bipolar word-pairs which are Like-Dislike, Ugly-Beautiful, Cool-Warm, Soft-Hard, Elegant-Vulgar, Loud-Discreet, Feminine-Masculine, Pleasant-Unpleasant were used to rate all the film clips with Likert scales. The color tuning process is performed on the DaVinci Resolve software that comes with Blackmagic Design 2.5K machine. The results indicate that adjusting color can stimulate different impression while people view movie. |
