Smartphone Camera Survey

In many users' pockets consumer-level digital compact cameras have been replaced by smartphones. The cameras of the latter don't usually have zoom lenses or xenon flashes but image sensor technology has been rapidly improving and clever software processing helps rival, and in some cases even surpass, image quality of dedicated cameras. Add large high-resolution screens for image framing and viewing along with the ability to add special features and new shooting modes by installing apps to the mix, and it's no surprise that for many the smartphone camera has become an important piece of photographic equipment.
