Mountain Lodge Light and Shadow

由专筑网李韧，王帅编译

我最近在进行山地小屋项目，其中有几个场景，我将其进行可视化表达设计。其中的一个关键场景便是连接山地和建筑的桥体，我将这个空间构思为沉思的场所，这个角度的选择比较特殊，因此我会介绍一下自己的想法，说明如何保持画面平衡等问题。

对于此类图像，光线的运用非常重要，下面我将着重介绍其中的光影表达。

As I continue to develop my Mountain Lodge Project, there are a couple of areas that I am using visualization to study the design a little more closely. One of the key moments is a bridge that connects the tower to the mountain side. I had envisioned this space to be an intimate and contemplative place. Picking the viewpoint was difficult because I am trying to narrate several ideas such as the procession from the clean and minimal architecture to the wild mountain side. The bridge landscape needed to strike a balance somewhere between the two to soften this transition.
For an image like this, light ended up being the primary driver to manage hierarchy and eye movement. Below is a little breakdown of how I used light to place the focal point exactly where I wanted it to be.


1、模型与基础渲染

如上图所示，这是SU模型的截图，模型自身非常简单，我只是添加了一些肌理而已。

1. Model and Base Rendering
Above, a screenshot of the Sketchup model. The model itself is simple and much of my time went into building some textures.

然后通过V-Ray基础渲染，来表达一些基本的光影。因为在后期我会通过PS来进行调整，因此在此时我只关注光影的正确性。

Above, the V-Ray base rendering shows the dappled light effect obtained by adding some simple, light low poly trees. I knew I would be replacing these out with Photoshop trees, I was only concerned about getting the shadows to read properly.

在设置太阳位置时，我比较关注的是桥体的定位，1、因此，我让建筑的背面位于阴影之中，2、桥体的左侧位于阳光之下，3、然后光线逐渐移动，再通过树影来增加画面景深感。

When setting up the sun location, I was focused on drawing attention to the bridge. 1- Therefore, I placed the back of the building in shadow, 2- left a portion of the bridge directly in the sun, 3- and then slowly fading the bridge back to dark using the tree shadows.


2、加入背景信息

然后我为画面添加了一些背景信息，例如一些山峰，以及桥体两侧的树木。

2. Inserting some Context
Next I added in some context. I stitched in some mountains and followed that with trees flanking both sides of the bridge.

背景树木对于图像来说至关重要，因为这样能够将人们的注意力吸引在主要桥体之上。1、我让树木呈现暗色，这样能够突出画面重点，2、同样运用树木来形成图面的对角构图方式，让人们的视觉焦点集中在图像中央的桥体上。

The context trees are crucial to this image because they provide the frame that help draw attention back to the bridge. 1-The trees themselves were darkened considerably so that the bridge and background mountains remained the only objects in direct light. 2- I also used the trees as a way to create some strong diagonals in the composition to help naturally draw the eye back to the bridge in the center of the image.


3、植物的添加

接下来我在图像中添加了一些植物，但没有调整不同图层的色调，我主要想要展示图面的色彩、对比度，以及不同树木和植物所产生的肌理层次感。另外，这也可以显示出，在未添加光影之前，整个图像看上去便相对缺乏一些细节。

3. Vegetation
I am showing the image with all of the vegetation in place, but no toning done to the individual layers. I wanted to show just how much some of the colors, contrast, and levels were adjusted from the original tree and shrub textures. More than anything, it shows how flat an image can be if time is not spent thinking about light and shadow in vegetation.

这张图与上面那张图的布局完全一致，只是添加了一些光影，例如有的树木呈现为深色，这样看上去图像会更加有细节，例如在绿色桥体旁侧的一些光线亮点，这给植物带来了新的活力，同时也让桥体焕发出清晨的舒适感。

Above is the exact same image, but now with the vegetation fully toned. Some of the trees moved to almost pure black, with just a little detail. Little things like adding small highlights along the edge of the green wall give the vegetation dimension, but also add to the cozy feeling of the early morning bridge experience.


4、简约、微妙的效果表达

最后，我添加了一些小效果，例如将桥体和植物上的光线亮点增大，并在图像的右侧增加了一些眩光效果，同时让建筑的顶部刷亮一些，提升画面饱和度，这样能够让画面更加引人注目。这样做的好处还在于我能够从中构思出新的设计想法，以及对材料运用的理解。另外，在这个项目中，我运用了大量耐候钢，这样能够让图面看起来具有暖色气息，同时与周边的绿色景观环境形成呼应。

4. Simple, Subtle Final Effects
Finally, I added just a few small effects at the end. I amped up some of the highlights on the bridge and vegetation, and added a touch of glare to the right side of the image. I also lightened the top of the tower and increased the saturation to avoid the architecture feeling too heavy and uninviting. The best thing about the image is it helped me make quite a few decisions regarding the direction of the design and some of the materials that I wanted use. Most notably, I ended up using Corten Steel for much of the project which brings in a ton of warmth and also works well with all of the green tones of the surrounding landscape.
