No, mirrors are not needed for all cameras to take photos. The mirror is only used in a reflex camera (a camera where you look through the same lens as the sensor/film).
Small point and shoots, rangefinders, and large format view cameras do not use mirrors.
No a camera has the lens,( a shutter), (an aperture), and a lightproof box. I'm very sure it doesn't have a mirror
no there are not but there is a reflective thingy that captures the picture
You can take pictures underwater, as to regular cameras you cannot take picture underwater

Cameras can only take one picture at a time.
The picture in picture function on cameras is for when one would want to record a video as well as being able to take a picture. The picture in picture that one would find on a TV set, would allow one to watch 2 TV shows at once.
DSR cameras allow you to take clear pictures. The higher grade your camera is, generally, the better and clearer the picture that it enables you to take with it.
with digital photography you can see your picture in an instant. If you don't like the picture you can erase it and take a new one. This is not possible with a film camera.
The parallax error happens when you take a picture using your digital camera and the picture does not appear to look the same as it did in the viewfinder. The cameras that may have this error occur are the twin lens reflex cameras and cameras that include viewfinders.
They don't allow cameras in the city.
Cameras and reflecting telescopes gather light using mirrors and lenses.
There are many different Nikon cameras. The compact digital cameras from Nikon are mainly simple "shoot and point" cameras where you open the shutter, point the camera at what you want to take a picture of and press the shutter. Other Nikon cameras have an interchangeable lens and adjustable focus to improve picture quality.
