Ps慢門堆棧疊加腳本—類似多重曝光效果的做法

1、Ps慢門堆棧疊加腳本類似多重曝光效果的做法以下為腳本全文（版本：20120911），使用時請選擇全部的藍色字體，另存為StarTails.jsx：/*功能描述：本腳本(StarTails.jsx)可以疊加星軌、實現(xiàn)星軌拖尾效果、實現(xiàn)慢快門效果在XP+CS5(32bit)和WIN7+CS6(64bit&extended)上測試通過，能夠正常運行本腳本不需要extended版本的Photoshop就可運行，而且運行速度更快使用說明：一.將連拍的多個文件轉(zhuǎn)化為圖層，使用Photoshop的文件-腳本-將文件載入堆棧 文件數(shù)不能(也不建議)超過100，超過的話請拆分并多次運行；文件數(shù)也不能是2個或者以

2、下，因為沒有這個必要吧？二.將本段腳本存成StarTails.jsx文件，通過Photoshop的文件-腳本-“瀏覽”打開StarTails.jsx三.出現(xiàn)StarTails的界面后，根據(jù)需要選擇不同的功能并進行簡單的設置 1.疊加星軌：選取最大值，保持最小/最大不透明度為100%不用修改，不需要復選進行圖層倒置 2.疊加星軌并實現(xiàn)星軌的拖尾效果：選取最大值，修改最小/最大不透明度，根據(jù)需要復選進行圖層倒置 3.疊加連拍的圖片，實現(xiàn)慢快門效果：選取平均值即可(注：最大值和平均值選項是模擬堆棧模式的最大值和平均值，效果幾乎相同，但不完全等同)此腳本Free，使用和傳播意味著你已經(jīng)充分讀懂了本腳本
