黄金分割:12世纪的意大利数学家可以教摄影师关于构图的知识

分享: 

A lost of people know about the 三分法则, the s-curve as well as other elements of photographic composition. Let's have a look at something that is a little more advanced in the world of image composition that was discovered by a 12th century Italian mathematician called 斐波那契.

黄金分割介绍

黄金分割只是一个合成规则,该规则规定通过将帧数除以1.6数倍即可获得构图良好的图像。

通过这样做,您将获得如下模式:

斐波那契最著名的是开发了一系列将前两个数字相加的数字序列:

0,1,1,2,3,5,8,13,21,34,55…

当您将连续的数字相除时,您会得出1.6,这是比例中数学的关键(因此它与摄影的关系)。当您将Fibinacci序列应用于矩形时,您会得到一个带有正方形的平铺,其边长为连续的Fibonacci数字。每个正方形大约是上一个正方形的1.6倍。像这样:

如何使用黄金分割

图像胜于雄辩,因此,请查看此图像及其下面的图像,以了解黄金分割在行动中的几乎完美应用。比例和成分是教科书《黄金分割》。

Now, this one is a lot more difficult than say, the 三分法则 to apply to your photos. However, with practice you will get better. The great thing is that the Golden Section adds another tool to your arsenal of composition.

The 三分法则 is a very crude approximation. So crude that it is basically wrong. Anyone doubting this please read Andreas Feininger’关于构成的书。

我真的很喜欢光语者的文章,但是这次“textbook example”是错的。可以看到/感觉到定位不协调。它没有’t even adhere to the 三分法则. The Mona Lisa is a 教科书示例 with many golden sections featured.

作为附录’d想补充一点,尽管“妈妈玛莎(Moma Lisa)”“golden rectangles”(对于比例),这可能不是使用黄金比例进行展示的最佳示例。

前一段时间我获得了两个“grid”覆盖与我一起“rule of thirds” overlays. One was a Golden Section overlay that divided into 9 sections like the 三分法则 overlay and the other was the Spiral overlay based on this concept. Often when cropping images before I varied from the 三分法则 overlays just on gut reactions and liking the image better with breaking the rule. So I went back with the 斐波那契 格 to see how it matched with these variations and nearly always it mapped perfectly to my gut instincts!!!! This really amazed me and made me much more aware of these 格s instead of 三分法则 which I rarely use anymore. Good luck to all. PS when beginning the 三分法则 is an easy way to get started in the correct direction, but as you advance it is worth looking at 斐波那契.

更多:斐波那契螺旋线是此概念的真正应用,因为它涉及到开放空间的比率平衡。斐波那契“grid I mentioned is a much simplified approach that is not a true application but is useful to get started on this road. To make one, you simply take a rectangle of the ratio you camera uses and make a parallel line to each side that is in from the edge 60% that results in a 格 that is very similar to the 三分法则 but has a smaller center rectangle. As you grow you start being more aware of the other content or lack there of (negative space). It really gets interesting when you have secondary points of interest or even more.

简洁地说,’有点割断了数学和在作曲中使用黄金分割的概念。您的图表骨架没有’不会使用图像的整个画面,这会使那些不了解图像的人感到困惑’我对黄金比例螺旋和成分了解不多。现在有几本关于工作室绘画的好书,详细讨论了组成部分,您应该参考。伟大的思想,良好的信息可以传递,但知识更深入。
