黑白照片变彩色照片工具
When you first start getting into photography, it’s very easy to fall into a habit of converting almost every image you take to black and white. I know I did it.
刚开始摄影时，很容易养成将几乎所有拍摄的图像都转换为黑白的习惯。 我知道我做到了
The thing is, while black and white images can look classy or cool, they’re not always strong images. Removing all the color can take away from a photo if you don’t do it right.
事实是，虽然黑白图像看起来很经典或很酷，但它们并不总是很强。 如果操作不当，则删除所有颜色可能会使照片无法使用。
So with that in mind, let’s look at how to take good black and white photos.
因此，考虑到这一点，让我们看一下如何拍摄优质的黑白照片。
是什么构成了好的黑白照片？ (What Makes a Good Black and White Photo?)
Unless you suffer from a really rare eye condition, you don’t see the world in black and white. Colors are a huge part of how our vision works, and are really important in how we see and interpret different things.
除非您患有非常罕见的眼疾，否则您不会看到黑白的世界。 颜色是我们视觉运作方式的重要组成部分，对于我们如何看待和解释不同的事物而言，色彩确实非常重要。
When you remove the color from an image, you’re separating it from the reality. A color photo is, at least superficially, a representation of a scene that existed, but a black and white photo can only ever be an interpretation of something. It can never show something as it actually was, but it can be a really good way to show how you felt about something. The best black and white images make that emotion very clear.
当您从图像中删除颜色时，就是将其与现实分离。 彩色照片至少在表面上是对存在场景的表示，但是黑白照片只能是对某种事物的解释 。 它永远无法显示出真实的东西，但是它可能是显示您对事物的感觉的一种非常好的方法。 最好的黑白图像使这种情绪非常清晰。
In a black and white image you’re left with two things: tone and texture. The tones are the shadows and highlights in the image. The texture is all the little variances between the tones. These are what make a black and white image work. Not every photo will make a good black and white image; if the tones and textures aren’t there, it’ll just look boring. The photo below looks awesome in color but drab in black and white.
在黑白图像中，您剩下两件事：色调和纹理。 色调是图像中的阴影和高光。 纹理是色调之间的所有微小差异。 这些就是使黑白图像起作用的原因。 并非每张照片都能制作出优质的黑白图像。 如果没有色调和纹理，那将看起来很无聊。 下面的照片在颜色上看起来很棒，但在黑白下显得有些单调。
If you look at the image of the mountain above, you can see all the tones and textures. You have the bright spots where the setting sun is hitting the snow, the dark rocks, and the smooth snow and sky. Everything plays well together.
如果您查看上方山峰的图像，则可以看到所有的色调和纹理。 您会看到落日照在雪地上的亮点，黑暗的岩石以及光滑的雪地和天空。 一切都进行得很好。
技术细节 (The Technical Details)
Unless you’re shooting film, black and white conversions are best done in post-processing. Most DSLRs and mirrorless cameras have a black and white mode, but all that does is take a color photo and desaturate it in the preview. The color information is still there if you want it.
除非您要拍摄电影，否则最好在后期处理中进行黑白转换。 大多数数码单反相机和无反光镜相机都具有黑白模式，但是要做的只是拍摄彩色照片并在预览中将其去饱和。 如果需要，颜色信息仍然存在。
When you’re shooting images that you think you’ll want to convert to black and white, you need to give yourself as much room to play in post-processing as possible. This means you need to shoot RAW.
当您拍摄想要转换为黑白的图像时，您需要给自己尽可能多的空间来进行后期处理。 这意味着您需要拍摄RAW 。
One big mistake new photographers make is that they shoot for the exposure they want, rather than one that gives them the best options later. Even if you know you want a dark, moody black and white image, you shouldn’t shoot it that way. You should shoot a well exposed image and then use Photoshop (or any other image editing app) to make it dark and moody.
新摄影师犯的一个大错误是，他们为自己想要的曝光进行拍摄，而不是后来为他们提供最佳选择。 即使您知道想要一张深色的，喜怒无常的黑白图像，也不要那样拍摄。 您应该拍摄曝光良好的图像，然后使用Photoshop(或任何其他图像编辑应用程序 )使它变暗且令人讨厌。
Look at the photo above. That’s what the image below looked like straight out of camera. I knew I wanted a deep, dark, moody image but if I’d shot it that way, I probably would have messed up the exposure and ended up with an unusable image. By shooting a neutral exposure, I was able to get the shot I wanted.
看上面的照片。 这就是下面的图像看起来像是直接从相机出来的样子。 我知道我想要一张深，暗，喜怒无常的图像，但是如果以这种方式拍摄，可能会弄乱曝光并最终导致无法使用的图像。 通过拍摄中性曝光，我可以拍摄到想要的照片。
To get an accurate exposure, it’s often easiest to let the camera do some of the work. Put it into aperture priority mode, set your aperture and ISO, and take a test shot. If the test shot looks underexposed or overexposed, adjust the exposure compensation and take another. Once your exposure looks relatively neutral, you’re good to go.
为了获得准确的曝光，通常最容易让相机完成一些工作。 将其置于光圈优先模式 ，设置光圈和ISO，然后进行测试。 如果测试镜头看起来曝光不足或曝光过度，请调整曝光补偿，然后再进行拍摄。 一旦您的曝光看起来相对中性，那就很好了。
Just make sure to reset the exposure every time you change location or lighting situation. There’s nothing more annoying than setting your camera up perfectly for one set of pictures but forgetting to change it before you take the next.
只要确保每次更改位置或照明情况时都重设曝光即可。 除了为一组照片完美地设置相机，而在拍摄下一张照片之前忘记更改它，没有什么比这更令人烦恼了。
其他技巧 (Other Tips and Tricks)
If you’ve got a relatively neutral exposure to work with and an image that you think will look good in black and white, all that’s left to do is convert it to black and white in Photoshop or or your favorite image editor.
如果您使用的是相对中性的曝光，并且您认为黑白图像看起来不错，那么剩下要做的就是在Photoshop或您喜欢的图像编辑器中将其转换为黑白图像。
You should never just desaturate your image or apply a random black and white filter in Instagram. You should always use an app like Photoshop or Lightroom that lets you control how each color is converted to grey. This control is what will let you make strong images. If you really want a simple, filter-based option, try Silver Effex Pro; it’s free.
您绝不应该只对图像进行去饱和或在Instagram中应用随机的黑白滤镜。 您应该始终使用Photoshop或Lightroom之类的应用程序，该应用程序可以控制每种颜色如何转换为灰色 。 通过此控件，您可以制作出精美的图像。 如果您确实希望使用基于过滤器的简单选项，请尝试使用Silver Effex Pro ； 免费。
Black and white images can take a lot more contrast than color images. In a color image, extreme highlights and shadows make a photo look surreal. In a black and white image, contrast just increases the difference between the tones and makes everything stand out more.
黑白图像比彩色图像具有更多的对比度。 在彩色图像中，极端的高光和阴影会使照片看起来超现实。 在黑白图像中，对比度只会增加色调之间的差异，并使所有内容更加突出。
With that said, don’t add too much contrast. Pay particular attention to your shadows. Texture is as important as tones. Don’t add so much contrast that all the small tonal variations disappear. Look at the tree in the image below; even in the darkest shadows there’s still some texture. This was a very deliberate decision. It would have been very easy to accidentally crush it to black.
话虽如此，不要增加太多的对比度。 请特别注意您的阴影。 纹理与色调一样重要。 不要添加太多的对比度，以使所有小的色调变化都消失。 看下图中的树； 即使在最暗的阴影中，也仍然有一些纹理。 这是一个非常刻意的决定。 意外地将其粉碎成黑色本来就很容易。
Black and white images are associated with very specific emotions. Things like calmness and tranquility, nostalgia and timelessness, class and elegance. This doesn’t mean your images have to always fit one of those emotions, but you just need to be aware of them. Some of the best black and white images contrast the subject with how people normally see black and white images.
黑白图像与非常特定的情绪有关。 诸如平静与安宁，怀旧与永恒，阶级与优雅之类的东西。 这并不意味着您的图像必须始终适合这些情绪之一，但是您只需要意识到它们即可。 一些最佳的黑白图像将拍摄对象与人们通常看到的黑白图像形成对比。
Portraits, landscapes and any abstract sort of photo tend to be the best images for black and white conversions (though they can be great in color too, obviously). When it comes to street photos, travel photos, and anything more documentary in style, color is usually a better bet. Converting the wrong images to black and white is a mistake I’ve made more than once.
肖像 ， 风景和任何抽象照片往往是进行黑白转换的最佳图像(尽管它们的色彩也很明显)。 当涉及街道照片 ， 旅行照片以及其他纪录片时，颜色通常是更好的选择。 将错误的图像转换为黑白图像是我不止一次的错误。
Making the viewer feel a certain way is the best reason to convert to black and white, but you can also do it simply to remove distractions. In a black and white image, a jarring, color-filled background can be reduced to a light grey.
使观看者有某种感觉是转换成黑白的最佳理由，但是您也可以简单地消除干扰。 在黑白图像中，可以将震颤的，充满颜色的背景减小为浅灰色。
Here’s a piece of advice I picked up from David DuChemin: if color doesn’t add anything to the image, you should convert it to black and white. It’s something I’m not sure I agree with, but there is a logic to it. To me, color will always tie your images to reality. However, it is worth converting any image where color isn’t a major part of the photo to black and white. Not only will it let you practice converting images, but it will give you a deeper understanding of the effects a black and white conversion can have. It won’t always make for a stronger image, but the process will make you a better photographer.
这是我从David DuChemin那里得到的一些建议：如果颜色没有为图像添加任何内容，则应将其转换为黑白。 我不确定我是否同意这一点，但是有逻辑。 对我而言，色彩将始终将您的图像与现实联系在一起。 但是，值得将颜色不是照片主要部分的任何图像转换为黑白图像。 它不仅可以练习转换图像，还可以使您对黑白转换可能产生的效果有更深入的了解。 它不一定总能带来更强的图像，但是此过程将使您成为更好的摄影师。
I love black and white photography. I spent a year shooting it almost exclusively. During that year I made a lot of mistakes by converting the wrong images or the right images badly. Now though, I’ve a much deeper understanding of when, why and how to convert an image to black and white. Hopefully, you do to.
我喜欢黑白摄影。 我花了一年几乎专门拍摄它。 那一年，由于错误地转换了错误的图像或正确的图像，我犯了很多错误。 现在，我对何时，为什么以及如何将图像转换为黑白有了更深入的了解。 希望你这样做。
