本教程教你簡單制作網點和線性光效果照片。

1.open the image you want to add the linear light and halftone dot effect too.
（打開你想添加線性光與網點效果的圖像）
    
2.duplicate the image to a second layer. label the layers "original image" and "halftone layer". move the "halftone layer" to the top of the layers window and make sure you have that layer selected.
（復制一個新圖層，命名兩個圖層為“原始圖像”和“中間調圖層”。移動“中間調圖層”至圖層窗口的頂部并確定你選中了該圖層。）
3.make sure you foreground color is white and your background color is black. with the "halftone layer" selected, select filter > sketch > halftone pattern from the menu bar. use the setting in the image below or play around some. click "ok" when you are done.
（確認你的前景色是白色，背景色是黑色。選中“中間調圖層”，從菜單欄選擇濾鏡>素描>半色調圖案。使用下圖的設置或自己設置。點擊確認。）
 
your image should look something like this（你的圖像此時看起來應該像這樣）
 
4.now we need to invert the halftone. on a pc hold down your ctrl key and press i, on a mac use the command key and press i. your image should now look something like this.
（現在我們要反轉這圖像。在pc上按住ctrl鍵同時按i，在mac蘋果機上按command鍵同時按i。你的圖像此時像這樣）
 
5.almost there, we just need to tweak the "halftone layer" some. select the layer and change its mode from "normal" to "linear light". you can also lowered the transparency some.
（此時已經差不多了，我們只需要調節“中間調圖層”。選擇圖層，將圖層混合模式從“正常”改為“線性光”。你也可以降低該圖層的透明度）
