Many smartphones have impressive cameras, and Apple just made a big upgrade with the new iPad. All that raises a question: Do you still need a separate digital camera? For quick online snapshots, maybe not. Smartphones are convenient. You always have one with you. They make uploading pictures a snap, and apps like Instagram add beautiful effects. But there are four features that no smartphone — but most point-and-shoot cameras — can offer.
Optical zoom is the No.1 difference between a phone and a digital camera. Phone cameras have "digital zoom," but that just blows up a small portion of a picture into a lower-resolution image. A "real" camera's optical zoom lens — the kind that moves in and out — physically magnifies distant objects to capture them at full image quality.Speaking of quality, the size of the image sensor matters. And a smartphone's size is teeny-tiny compared to even a cheap digital camera's size. The result is grainy speckles that are particularly noticeable in solid-color areas of your photos — and everywhere when you shoot in low light.
Also on the low-light topic is flash power.Emanuel scales back speed-camera hours. The little LED lights on a cellphone can't hold a candle to the full-fledged flash on any point-and-shoot. The camera's flash is also positioned to make the dreaded red-eye effect less likely.A standard feature on most point-and-shoots, optical image stabilization moves lens components or the sensor to counteract jitters when the camera shakes. Stabilization makes it much easier to capture sharp images in low light or at high zoom.
You are right. But, Camera has only one feature to capture photo and video. On the other hand, smartphone has multi-feature. cheap wireless spy camera has some more features in comparison to digital camera.
