Why do digital cameras need flashes?
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?
