How does a photography course present a reflective object precisely through a lens-noreply

Photography course: how to show the reflection object accurately through the lens? Shooting reflective surfaces or objects is a challenge for many photographers and enthusiasts, and it can easily destroy your work and cause you to fall into despair. Although reflection is a beast that cannot be tamed, it is not difficult to overcome it if we can master the rules. In the following article, the author will show how to effectively control the reflection, use it for its own purpose, and create powerful photography. Just like this still life picture, just using simple shooting techniques and necessary skills and equipment, but it has achieved good results. Typically, with a reflective surface like a mirror like reflection of light, so if the main light source and the camera shooting angle we image coincide or from the same direction, then this will make the high light reflective screen and a substantial part of overflow, lost precious details, so that the whole body looks the lack of texture and layers, the effect looks like in the top flash directly shoot out. The key to solving the problem is to understand the basic principles of light and how to use them, and the most commonly used is the reflection law that we contacted in physics lessons in junior high school. Roughly speaking, when light travels from a uniform material to another homogeneous material, the incident light, reflected light, and normal line are in the same plane; the reflected light and incident light are separated on both sides of the normal; the reflection angle is equal to the incident angle. Well, put aside the stiff physics theorem, it’s easy to understand for photography, and it’s actually telling us that when you’re shooting objects with reflective surfaces, remember to keep your camera at the same angle as the light source. The trick of shooting a reflective object is to use a larger light source and place it relative to the camera’s seat. For better results, I recommend the use of a studio flash and a large Softboxes, of course, you can also use some small devices, and cheaper way to shoot, such as ready for some white cardboard, an independent type, and flash trigger. The picture below is what I use these devices when shooting the scene: through the reflection of the white board, a flash of light to form a larger light source, the light has become more gentle, and able to shoot the main body to create a uniform shading effect, so as to avoid high light overflow. As an additional benefit, this light also helps to highlight the texture of the background stone. This technique is simple, but it can simulate the effect of multi lamp lighting. After that, we can also adjust the overall effect of the picture by trying different shooting angles and changing the position of the light source, including the stones and water droplets in the background, which are very important to enhance the impression of the photos. The following is a set of my test images, you can see the change the position of picture showing a distinct effect. As we have already known, the reflection angle of the light after the reflective surface is fixed.

摄影教程:如何通过镜头精准呈现反光物体?   拍摄带有反光的表面或物体对于许多摄影师及爱好者来说都是一个不小的挑战,稍有不慎它便可以轻易毁掉你的作品,并且令你陷入到绝望中。虽然反光是一个难以驯服的野兽,但如果我们能够掌握规则,克服它们其实并不困难。在下面这篇文章中,作者将展示如何通过有效地控制反光,将其为己所用,并创造出富有冲 击力的摄影作品。就好比下面这张静物照片,只是运用一些简单的拍摄手法和必要的技巧及设备,却取得了很好的效果。   通常情况下,一个带有反光表面的物体会像一面镜子般反射光线,因此如果我们图像的主光源与相机的拍摄角度重合或来自同一个方向,那么这种反光就会令 画面的高光部分大幅溢出,并丢失掉宝贵的细节,从而使得整个主体看上去欠缺质感与层次,其效果看上去就好像是用机顶闪光灯直接拍出来的。   解决问题的关键在于了解光线的基本原则以及运用它们的方式,其中最常使用到的是我们早在初中物理课上就接触到的反射定律。大致上说就是当光从一种均 匀物质射向另一种均匀物质时,入射光线,反射光线,法线处在同一平面内;反射光线和入射光线分居在法线的两侧;反射角等于入射角。   好了,抛开生硬的物理定理,对于摄影来说这其实很容易理解,它实际上就是要告诉我们在拍摄带有反光表面的物体时,切记不要让相机的机位与光源处于同 一角度。拍摄反光物体的诀窍是使用比较大型的光源,并且把它放置在与相机机位相对的位置。为取得更好的效果,我建议使用一盏摄影棚闪光灯和一个大号柔光 箱,当然你也可以使用一些小型设备,并且以更便宜的方式进行拍摄,比如准备好一些白色纸板、一个独立式闪光灯、以及引闪器。   下面这张图就是我利用这些设备进行拍摄时的场景:   通过白色纸板的反射,闪光灯所发出的光线形成了一个更大的光源,相应的其光线也变得更为柔和,并能够在拍摄主体身上创造出明暗过度均匀的效果,从而避免高光溢出。作为额外的福利,这种光线同时也有助于凸显出背景石板的纹理质感。   这种技巧虽然简单,但是却可以模拟出多灯照明的效果。在这之后,我们还能够通过尝试不同的拍摄角度以及改变光源的位置,来调整画面的整体效果,包括 背景中的石头和水滴对于提升照片的观感都是十分重要的。下面是一组我的试拍样张,可以看到通过变换位置,画面呈现出了截然不同的效果。   由于我们事先已经了解到光线在经过反光表面后的反射角度是固定的,这就使得我们可以决定哪个拍摄机位和光源位置比较容易取得更好的效果。   在上面这张示意图中,处于“family of angles”位置的光线将会直接产生反射光,而身处“family of angles”以外且来自与相机位置同方向的光线,将不会照射到镜面反光物体上。即便有些时候我们遇到的是光线角度并不是很明确的漫反射 光,“family of angles”也能让我们有机会去根据相机的位置来决定如何放置我们的光源。刚开始看时,我们可能会觉得所有这些有关光的技术信息有些令人不知所措,但一 旦你真正开始着手布置并进行拍摄,你就会发觉这其实并不困难。因此,让我们放手尝试,我相信你能够拍摄出很好的作品。相关的主题文章:
