Why do digital cameras need flashes?

April 8, 2005 / / 1 Comment

I’ve been wondering for a while why digital cameras need a flash to take pictures inside or under poor lighting conditions. Sure, some allow you to set the digital “film” at a higher ISO, but then you will also get grainier pictures. Why is that? Is there something in the technology that impedes them from allowing you to take good pictures under bad light conditions? Is it a foolish attempt to imitate film cameras? Does anyone know?

    Flashes are not only use to make the whole picture brighter but also to eliminate shadows. They only work if at a short distance from the subject and should be used even outside if you have the sun on the back or side to prevent hard shadows. Also if the light source is bad colors would be off without a flash.
