1. Avoid Oversaturated Color

1.避免饱和度过高的颜色

Oversaturation is an issue I see often. Many of the skyimages that I find online have this problem because the sky has beenenhanced or amplified to be more dramatic and catch viewersattention. However, too much color saturation in the sky willoverpower the colors in the architecture and ground plane ruining the hierarchyof the illustration. To fix this, I go into “Image>Adjustments>HueSaturation” and I move the “Saturation” slider to the left to remove some ofthe color.

使用饱和度很高的色彩是我经常遇到的一个问题。我在网上找到的天空图片通常都会有这个问题，因为这种饱和度高的颜色能够快速吸引观众的注意力。但是一张使用饱和度高颜色的天空将会破坏建筑和地平面的色彩层次感。为了解决这个问题，我们可以点击“图像/调整/色相饱和度”，将“饱和度”滑块向左移动到合适的位置。

2. Avoid Awkward or Unnatural Colors

2.避免诡异或不自然的色彩

Unnatural color brings with it similar issuesas oversaturation. Unnatural sky color can throw the whole imageoff from the start making it difficult to pull off a successfulcomposition. Not only that, it creates a “Photoshopped” look insteadof looking harmonious with the architecture and ground plane. Due tothe many gradients and color tones, I prefer just finding another skyvs. trying to alter or fix the unnatural colors. However, ifI really like the cloud forms or texture of the image, I sometimes willdesaturate the color, and then use the color of a different sky overlaid ontop.

使用不自然的色彩会带来和过度饱和类似的问题。如果使用一张有奇怪色彩的天空，则会在一开始就会使完成一张完美的作品变得异常困难。不仅如此，因为过多的色彩渐变和色调，奇怪色彩的天空会感觉到强烈的“photoshopped”感，同时也破坏了建筑和地平面之间的和谐。我宁愿重新找一张天空而不是尝试去调整这种不自然的颜色。但是，如果我真的喜欢这张天空中云彩的形状和样式，我会减淡色彩，然后使用不同天空的色彩进行叠加。

3. Minimize Overly Busy Skies

3.避免复杂的天空

As much as you may like clouds, too many will hurt the reading ofthe image. Simply put, they take all of the attention away from thearchitecture. However, there is a fine line between distracting anddramatic. I tend to like cloudy skies, but I will dilute the image bydesaturating the color and fading out the detail so that the texture issofter. An easy way to fade the detail is by finding a sky with no clouds,just color, and setting that as the base sky. Then take the cloudysky, set that layer on top of the just-color sky, and lower the opacity so thatthe clouds read much lighter.

过多复杂的云会影响我们对图面的阅读。简而言之,这些复杂的云会潜移默化的吸引我们的注意力，而不是在建筑主体上。但是,还是有一个很好的方法去平衡。我通常比较喜欢多云的天空,但我会减淡图片的色彩以及稍微模糊一些细节，这样让天空的质感更加柔和。方法是我们首先找到一张没有云的天空，并以这张只有颜色的天空为底图。然后将之前那张多云天空放在这张图的上面，并降低多云天空的透明底使云彩更加适合阅读。

4. Wrong Sun Direction

4.错误的太阳的方向

This is one of those situations where you look at an image,and something seems off, but it is not clear what is wrong. However, oncea light source issue gets corrected, the image reads dramaticallybetter. This holds true for other Photoshopped elements such asentourage shadows and trees shadows. The more that the light sourceof all of the elements relate, then the better the entireimage will read as a single cohesive illustration instead of a bunch ofsingle Photoshopped elements.

我们经常遇到一种情况，当我们在看一图片的时候，我们感觉到好像缺少了什么但是又说不清楚。但是，一旦将光源的错误纠正后，整个图片立马看起来好很多。同样的道理也适合其他的对象，比如阴影。当相关对象的光影一致性后，整张图片就会看起来更加和谐统一，而不会感觉到它们是一个个孤立对象组合。

5. Look for the Correct Perspective

5.找到正确的视角

This idea is more important or less important depending on theview. However, scenes showing a lot of depth will read muchbetter with a sky that shows the correct perspective. In the exampleabove, the clouds have almost no perspective, meaning the clouds don’t changein scale as they recede into the distance and get closer to the horizon whichcauses the background reads much flatter.
这一点的重要性取决于视野。然而,拥有一张正确视角的天空的场景在表现许多图片对象深度的时候会更加适合阅读。在上面的案列中，云几乎没有一个合适的视角，这就意味着这些云没有在形状大小上发生合适的变化，并且云与地平线靠的很近，这样会使背景图片看起来太扁平化了。

6. Don’t Be Afraid To Go Simple

6. 不要害怕简单

You don’t always need to show clouds. Sometimes, the perfectgradient is all that is needed to set the right tone for animage. This move creates a calmer scene and helps to highlight thearchitecture and ground plane.
你不是总需要去表现云，有时候设置一个正确的图像基调就已经足够了，这样就你创造了一个平和的场景，同时也凸显了建筑和地平面。

The Final Image

最终的图像

The sky I ultimately chose was a cloudy one with pockets ofblue. This allowed me to play up the sunlight coming from the left andgive the overall image a dramatic light to dark gradient. I combined twodifferent cloud images using a similar process as described in tip #3. Ifound a sky with no clouds and great color and then combined that with a cloudysky. By adjusting the opacity of the cloudy sky, I was able to zero in ona good balance of color and softness.

最终我选择了一张隐隐透露着蓝色多云的天空，这样我便可以随心将阳光放置在左边，给整张图片一个从亮到暗的一个色调的过度。然后我使用与第三点类似的方法结合了两张不同云彩的图片。我找到一张没有云彩但是有非常棒的色调的天空，然后叠加到一张多云的天空。然后通过调整这张多云天空的透明度，我能够专注于两张图片一个很好的平衡感和柔和感。

Once I had the sky, I amplified the warm and cool tones usingcolor overlays and added more shadow at the base of the image. All thesemoves help to start the viewer’s eye on the left side of the image, and slowlymove it to the right over the bridge and to the train on the right, mimickingthe path pedestrians take. In this way, I am using the light started bythe sky to help tell the story of the project.
一旦我有了天空后，我会使用颜色覆盖来增强画面的冷暖对比，同时在图面的底部添加更多的阴影。所有的这些操作有助于读者首先被左边的色彩吸引，然后会慢慢的将视线通过桥移到右边的火车上。通过这种方式，我使用由天空发出的光线去诉说了这个项目的故事。
