vray物理相机教程 VRay Physical Camera Tutorial/vray物理相机教程 翻译by: If you haven’t used a manual photo camera in real life, this tutorial is for you! 如果你还没有使用过相机在现实生活中,那本教程就是给你的! As a photographer, I’ve always found the settings for VRay Physical Camera very natural and self-explanatory. 作为一个摄影师,我经常发现,设置VRay物理相机效果很自然且不言自明。 So it came as a bit of a surprise to find out how many people actually find them frustrating and hard to understand! 但是发现有不少人觉得它难和难以理解! So here’s my attempt to simplify it a bit! 所以我试图简化一点解释这个! Focal Length/焦距 This is the first parameter you should pay attention to. 这是第一个应该注意的参数。 It is set in millimeters and works just like changing a lens on a SLR camera. 它被设置为毫米，工作原理就像改变一个单反相机的镜头。 Low value = large angle of view (Wide Angle lens in photographer lingo) High value = small angle of view (Tele Photo lens). 低值=大视角(广角镜头在摄影师行话里)高值=小的视角(Tele照片镜头)。 Just look at this image to see what I’m talking about! 看看这张图片就像我所说的那样! Keep it realistic!\保持真实! It is scientifically proven that the focal length of a human eye is ~45mm so images rendered with this value will look most natural to people. 科学证明,人类的眼睛的焦距是45毫米所以图像渲染与该值相近将看起来最自然。 Wide angles will make rooms look larger, objects further away and distorted and stretched out. 宽角度将会使房间看起来更大、物体更远并扭曲。 Tele photo lens (50mm+) will make objects appear closer to viewer and to each other as well as make spaces seem smaller. Tele照片透镜(50毫米+)会使物体看起来更接近镜头，使空间显得更小。 SLR cameras use lenses from 6mm to 800, but most of the time it’s more like 16mm to 300mm. 使用单反相机镜头从6毫米到800,但大多数时候使用16毫米到300毫米。 The extremely wide or tele lenses can cost as much as a nice used car, so most people don’t have a chance to buy them. 宽屏或电视镜头的售价高达一辆不错的二手车,所以大多数人没有机会去买他们。 This means that 99% of the photos you see everywhere are taken with a lens in 16-300mm range. 这意味着99%你看到的图片都是用一个16 - 300毫米的范围镜头拍摄的。 That’s why you want to stick to this range in your 3D renderings. 这就是为什么你要要坚持这个范围在你的3d渲染里。 Sure, it might be fun to use very wide le
