Holga+宝利来机背测试报告
 
准备一台没问题的HOLGA120（当然漏光不算问题了），最好可以接闪灯或者有内置闪灯的。

把机背和片闸取下 有闪灯电池的可用黑胶带粘起来。
 
这就是宝利来那神奇的机背，看一下就知道怎么装，跟原本的机背一样的装法。
 
机背的另外一面
 
机背打开的构造，右边是放底片的地方。最好有一只闪灯，不然曝光时间就放长点吧！
 
比较不方便的是，装上机背你就无法看取景窗了，所以要先取景，调整脚架位置，但还不用把相机固定在脚架上，脚架调整好了就不要乱动了，因为这是你取好景的位置。
 
然后再把神奇的机背装上，这时可以把整个机构（机背、闪灯、holga相机）装起来，固定在脚架上。
 
拉掉宝利来的盖膜
 
再把插刀抽起来，这时候该是按下快门的时候了，你可以用侧光表侧光，也可以猜的 ：），Holga的光圈是8，所以室内最好用B门＋闪光灯，或者你在光线充足的室外拍摄。
 
拍完，把片子拉出来，和玩传统的宝利来一样。
 
好了，别急，等待90秒钟以后，把贴膜揭开，就ok啦！
 
看看最终效果！Holga的暗角加上宝利来的朦胧感是不是天生一对呢？呵呵。
