《HDR高动态光照渲染技术教程》xTrain High Dynamic Range (HDR) Mastery Ben Willmore

本视频教程是由xTrain机构出品的HDR 高动态光照渲染技术教程,xTrain High Dynamic Range (HDR) Mastery Ben Willmore,Photoshop 大师 Ben Willmore 将透过本教程,逐步讲解如何掌握高动态光照渲染技术 (HDR)。
高动态光照渲染 (High-Dynamic Range,简称 HDR),是电脑图形学中的渲染方法之一,可令立体场景更加逼真,大幅提升场景的真实感。

现实中,当人由黑暗地方走到光亮地方,眼睛会自动眯起来。人在黑暗的地方,为了看清楚物件,瞳孔会很大张开,以吸收更多光线。当突然走到光亮地方,瞳孔来不及收缩,所以唯有眯上眼睛,保护视网膜上的视神经。

但是电脑是死物,唯有靠 HDR 技术模疑这个效果——人眼自动适应光线变化的能力。方法是快速将光线渲染得非常光亮,然后将亮度逐渐降低。HDR 的最终效果是亮处表现为鲜亮,而黑暗处的效果则是能分辨物体的轮廓和深度,并不是以往的一团黑。

HDR 是目前追求画面逼真度最新最先进的手段,在 HDR 的帮助下,我们可以使用超出普通范围的颜色值,因而能渲染出更加真实的 3D 场景。

xTrain High Dynamic Range (HDR) Mastery Ben Willmore
Ben Willmore shows you step-by-step how to master High Dynamic Range (HDR) imaging. This is currently one of his best-selling online classes, and it’s now available on DVD!
HDR Mastery offers digital photographers the training they need to take their digital photographs to a new level. HDR is the process of taking a sequence of exposures, and then combining them while lightening underexposed areas and darkening 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.
There are 4 classes included in this DVD course:
• Shooting for HDR
• Merging Exposure
• Processing HDR Files
• Enhancement
