《正片與負片的曝光關係!》
#Darkroom

正片有許多名稱,像是反轉片、幻燈片或著是正像底片等等,在一般的沖洗流程當中,以柯達制定的E-6規範為最主要的沖洗流程,不過當年每個製作正片的公司,都有推出自己家品牌的沖洗藥水,譬如富士家的CR-56、愛克發家的AP-44,不過即便每一家的藥水名稱都不一樣,但是沖洗正片的藥水都是共用E-6流程,因此每一家的正片都可以使用同一種藥水沖洗。
負片就是大家最熟悉的底片,柯達制定的規範是C-41,那麼同樣的是每一家也有自己獨特的名稱,像是富士家叫做CN-16,大多數的負片沖出來都是琥珀色,有一層淡淡的紅褐色,現在已經很少有用C-41沖洗的燈光底片,不過如果你有幸找到古早時候的鎢絲燈白平衡,底片的片基會比較偏淡淡的黃色。
這次是Darkroom帶來的曝光測試,讓你可以直接了了正片與負片之間在曝光之間不同的差別!

#畫個重點
1.負片比正片更寬廣的寬容度,允許更大的光差進行拍攝。
2.彩色負片多曝光可以增加色彩的飽和度。
3.彩色正片則是要精準曝光,並盡量避免高對比的環境。
Exposure latitude comparison 👉🏼 E-6 Slide Film vs C-41 Color Negative! The first frame is was metered for the brightest highlights which resulted in underexposure and we opened up by 1 stop until the 6th frame which was metered for the shadows. As you can see, color negative film has much better exposure latitude than slide film does. When shooting with color negative it’s best to err on overexposure because it rarely blows out the highlights. When shooting with slide film you need to pay close attention to your exposure, metering for the mid-tones/skin-tones and avoid shooting in very contrasty light if possible. #tdr_meteredfor #thedarkroomlab
