I use the internal speedlight of my D70 to flash the object in daylight to reduce the handshaking problem. Give you a photo for your reference! 用尽旧镜微距能力，专人指导使用微距滤镜，拍尽微距世界！
The speedlight will pre-flash that area and lock that exposure into memory.I might caution you that you have 16 seconds to then recompose and take the shot. 闪光灯会预闪并把曝光值记忆下来，注意你只有16秒的时间重新构图拍摄。
Automatic filter detection: Speedlight automatically adjusts the attached camera's white balance settings when a fluorescent or incandescent color filter is used. （自动滤镜检测：当使用萤光或者白炽光滤镜时，闪灯可以自动调节相机的白平衡设置。）
see p. 199 : set the speedlight flash mode to TTL ! 看完贴子要记得回覆哟，按此可以快速回主页!
“In order to do all of this - get soft directional light from my speedlight - it is essential that my flashgun has a head that can both rotate and swivel. 就是说，闪光灯要能够左右旋转与上下弯折。如果闪光灯不能实现这2个功能，作者认为买这样的闪光灯就基本等于浪费钱了。
