Canon A70 and Slave Flash

by megaweb (4/3/2005) 



Introduction
    Canon A70 is a 3.2 megapixel consumer camera with 3x optical zoom and manual mode. With a little bit of customization, you can actually take good exposure shots in low lighting environment in the distance up to 5 metres. This setup is light, cheap and similar to my A70 Super macro setup.

    By turning the slave flash head position (see diagram), you can control the exposure easily. You will be amazed to see consumer camera like Canon A70 which able to produce good exposure shots. If you own a Canon A series or other consumer digital camera which support manual mode, it is worth to try this setup.
