My renderings are usually no larger than 750 pixels wide. If you’re working with anything considerably larger then your results will differ slightly.
(我的渲染图像通常都不超过750像素宽。如果你正以任何更大的尺寸进行工作,那么结果会稍有不同。)
Scan your drawing of the car. Don’t worry if the lines are a bit rough we will be drawing them again in Photoshop.
(扫描你汽车的草稿。如果线条有一些粗糙也没什么关系,我们将再PS里重新勾线。)
When you first open the image in Photoshop it will be on a layer named Background. Double click on Background in the Layer Palette and a New Layer dialog box will appear. Call the layer Original and click ok.
(当你第一次再PS里打开这张图片,它应该在名为“背景”的图层里。在图层面板中双击背景层,然后会弹出一个层属性对话框。将其更名为“原图”,然后确定。)
Rotate the image (Edit > Free Transform, or ctrl + T), to give it a nice angle.
(旋转图像(编辑》自由变换,或是CTRL+T),以获得一个合适的角度。)
Use the Pen Tool, (P), to draw over the original lines, and the Direct Selection Tool, (S), to refine the paths.
(使用钢笔工具(P),重新描绘原来的线条,然后用直接选择工具(A)来提取路径。)
(Notice the pen tool has a small black triangle/arrow in the bottom right hand corner, this means that there are additional tools hidden in that tool. To access these tools click and hold the left mouse button. The Pen Tool has the following additional tools.
(提示:钢笔工具的图标右下角有一个小三角块,这表示还有其他的工具隐藏在它里面。你可以通过按住左键不放,察看图标下的工具列表。如下图所示。)
Use the bottom three to refine your paths. Add Anchor Point Tool and Delete Anchor Point Tool are fairly obvious and the Convert Point Tool lets you to redefine the anchor points and give a smooth corner).
(使用下面的3个工具来重新定义你的路径。添加锚点工具和删除锚点工具的作用很明显了,转换点工具允许你重新指定点的类型,以获得一个平滑的转角。)
Select the Brush Tool, (B), right click over the image and select brush of thickness 1.Make sure your Layers palette is visible (F7, or Windows > Layers), make a new layer and call it Outline.
(选择笔刷工具(B),在图像上右击,选择厚度为1的笔刷.确保你的图层面板是可见的(F7,或 窗口》图层),新建一个图层,命名为“轮廓线”。)
Select the Pen Tool, (P), again, right click and select stroke path and select brush from the dialog box.
(再次选择钢笔工具(P),右击,然后选择描边路径,并从对话框中选择画笔。OK)
Now click esc twice to hide the paths.
(现在点击ESC两次,隐藏路径。)
Make a new layer and call it Shadows.
(新建一层,命名为“阴影”。)
Make sure that the foreground colour is black or whatever colour you want for the shadows.
(确保前景色为黑色或者是你希望用做阴影的其他颜色。)
Using the Wand Tool, (W), Select the tyres and the shadow areas underneath the vehicle. Select the Rectangular Marquee Tool, (M), right click inside the selected areas and choose Fill... from the list of options. Make sure foreground colour is selected and click ok.
(使用魔棒工具(W),选择轮胎和车辆下的阴影区域。渲染矩形选框工具(M),在选择的区域中右击,从选项列表中选择填充。选择填充前景色,然后单击“确定”。)
