Using smartphone as a camera/video camera

Wouldn't it be nice to have a camera with you where ever you go. Having a camera on your smartphone makes this a reality and is super convenient. Camera phones are no longer the blurry, two megapixel things they were just a few years ago. With the latest technology you can take good pictures of day to day life where ever you go. The great thing is, even if you don't have a cell phone service plan, you can still use your old smart phone as a camera or video camera. Knowing this can save you hundreds of dollars compared to buying a new camera, especially that all they can do is take pictures. Just beware that some smart phones will require you to have a micro SD card installed in order to use the camera function. Taking pictures is another great thing to utilize that old smart phone.
