xTrain - High Dynamic Range (HDR) Mastery，高動態光照渲染技術教程。Photoshop 大師 Ben Willmore 將透過本教程，逐步講解如何掌握高動態光照渲染技術 (HDR)。
高動態光照渲染 （High-Dynamic Range，簡稱 HDR），是電腦圖形學中的渲染方法之一，可令立體場景更加逼真，大幅提升場景的真實感。
現實中，當人由黑暗地方走到光亮地方，眼睛會自動瞇起來。人在黑暗的地方，為了看清楚物件，瞳孔會很大張開，以吸收更多光線。當突然走到光亮地方，瞳孔來不及收縮，所以唯有瞇上眼睛，保護視網膜上的視神經。
但是電腦是死物，唯有靠 HDR 技術模疑這個效果——人眼自動適應光線變化的能力。方法是快速將光線渲染得非常光亮，然後將亮度逐漸降低。HDR 的最終效果是亮處表現為鮮亮，而黑暗處的效果則是能分辨物體的輪廓和深度，並不是以往的一團黑。
HDR 是目前追求畫面逼真度最新最先進的手段，在 HDR 的幫助下，我們可以使用超出普通范圍的顏色值，因而能渲染出更加真實的 3D 場景。
Course: High Dynamic Range (HDR) Mastery
Instructor: Ben Willmore
Photoshop Guru, Ben Willmore, shows you step by step how to master High Dynamic Range (HDR). HDR is the process of taking a sequence of exposures, allowing you to lighten your underexposed areas and darken your overexposed areas to better simulate what your eye would actually see. You will see how to best choose subjects for HDR, such as watching for movement, clouds, sensor dust, and when you can find the ideal light to master HDR. Ben will show you how to merge exposures to enhance or add an illustrative effect to your photographs.
