Last time I talked about Photoshop’s Multiply Mode and gave an example of how to use it to color line drawings. Here, I’ll show you how you can use Multiply mode to colorize black and white photos.
上次我谈到Photoshop的“倍增模式”，并举例说明了如何使用它为线条图着色。 在这里，我将向您展示如何使用“乘法”模式为黑白照片着色。
I’ll start with this gorgeous black and white photo that I downloaded from office.microsoft.com/clipart (the actual downloaded image is at higher resolution than this):
我将从从office.microsoft.com/clipart下载的这张漂亮的黑白照片开始 (实际下载的图像具有更高的分辨率)：
First, I’ll color the hair. I add a new layer above the photo, set it to multiply mode, and start painting away at her hair. I’ll make her blond by using different shades of light yellow, gold, and brown. (I use the lightest yellow in the natural “highlight” areas of the photo.) In the diagram below, you can see the layer in normal mode and also in multiply mode. The layer is also set at an opacity of 80%.
首先，我将染发。 我在照片上方添加了一个新图层，将其设置为倍增模式，然后开始画她的头发。 我将使用浅黄色，金色和棕色的不同阴影使她变成金发。 (我在照片的自然“突出显示”区域中使用了最浅的黄色。)在下图中，您可以在正常模式下以及在倍增模式下看到该图层。 该层的不透明度也设置为80％。
Next, her skin. I made another layer, set it to multiply mode, and airbrushed different shades of peach and pink until I thought it kind of looked normal.
接下来，她的皮肤。 我做了另一层，将其设置为乘法模式，然后喷上不同深浅的桃红色和粉红色，直到我觉得它看起来很正常为止。
Because I was a little sloppy with the airbrush, I added a layer mask to clean up some of the edges:
因为我对喷枪有些草率，所以我添加了一个图层蒙版来清理一些边缘：
Finally, I added yet another layer and painted on different shades of blue — again, the layer was set to multiply mode.
最后，我又添加了一层，并在不同的蓝色阴影上绘画-再次，该层设置为乘法模式。
And here’s my final result:
这是我的最终结果：
That took me about 10 minutes (the skin took the longest). If I were being paid for this project, I would probably duplicate the photo layer and play with changing the black/white using the hue/saturation dialog box to give the shadows more color. But then again, this is a free demo. So, enjoy!
那花了我大约10分钟(皮肤花了最长的时间)。 如果为此项目付费，我可能会复制照片图层并使用“色相/饱和度”对话框更改黑色/白色以使阴影具有更多的颜色。 但是再说一次，这是一个免费的演示。 所以，享受！

Next week I’ll get back to discussing more blending modes of Photoshop…
下周，我将回到讨论Photoshop的更多混合模式…
