How do cameras take pictures?
How can a device capture..well...life? Molecules or something? How do they record things? I understand how art portraits work(obviously), but how do cameras do that? It's hard to explain, but hopefully you get my point.

Hey,
Here is both film and digital.
Film:
Film cameras use photosensitive film to capture life. As you may know, your eyes see things by recording the reflected light from an object. Thats why when its dark, and there is no light to reflect, you can't see. The key to film is its photosensitivity. Photosensitivity means that something reacts with light. Basically when light goes through the lens and reacts with the film it hardens the emulsion. Emulsion is the mixture of silver and various other dyes depending on the type of film. Once the light has reacted with the emulsion on the film however, it does not become the picture. It has to be developed. Developer basically washes away the emulsion that has not been hardened by light. Thats why for most film, the image appears backwards, where darker areas are light on the film and lighter areas are dark. (Thats why its called a negative). Slide film, which appears as a positive, is a totally different story.
Digital:
Digital cameras use basically the same principal as film. The difference is that a camera sensor is electric and has pixels. A pixel is basically an spot that is electrified that will try to imitate the colour of the light that hits it. That is a very simplified analogy but it is essentially how it works. The data from the pixels are then stored on the memory card.
i hope that gives you a basic understanding of how it works
It depends on the model of the camera really. Some cameras today are both a video, and still picture camera in one. However, it should be digital. I would never buy anything that is under 3 megapixels, if it is a video camera. Alot of video cameras have lowe megapixels, which means bad quality pictures.
A Stereo camera can take photographs that appear "three-dimensional" by taking two different photographs that can be combined to create the illusion of depth in the composite image. Stereo cameras for making 3D prints or slides have two lenses side by side. Stereo cameras for making lenticular prints have 3, 4, 5, or even more lenses. Some film cameras feature date imprinting devices that can print a date on the negative itself.
camera is a device used to capture images, either as still photographs or as sequences of moving images (movies or videos). The term comes from the Latin camera obscura for "dark chamber" for an early mechanism of projecting images where an entire room functioned as a real-time imaging system; the modern camera evolved from the camera obscura.
Cameras may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A camera generally consists of an enclosed hollow with an opening (aperture) at one end for light to enter, and a recording or viewing surface for capturing the light at the other end. Most cameras have a lens positioned in front of the camera's opening to gather the incoming light and focus all or part of the image on the recording surface. The diameter of the aperture is often controlled by a diaphragm mechanism, but some cameras have a fixed-size aperture.
Traditional cameras capture light onto photographic film or photographic plate. Video and digital cameras use electronics, usually a charge coupled device (CCD) or sometimes a CMOS sensor to capture images which can be transferred or stored in tape or computer memory inside the camera for later playback or processing.
Cameras that capture many images in sequence are known as movie cameras or as ciné cameras in Europe; those designed for single images are still cameras. However these categories overlap, as still cameras are often used to capture moving images in special effects work and modern digital cameras are often able to trivially switch between still and motion recording modes. A video camera is a category of movie camera that captures images electronically (either using analogue or digital technology).
Depends upon what you are using. If your using film a tiny monkey well paint the picture on the film. If your using digital then a tiny robot monkey will paint a picture and then scan it into the camera flash card.
-These tiny monkeys are hard to find so that is why camera's cost so much.
There is a little monkey inside the camera that paints the picture.
You press a button and the robot just knows to take picture,s the human mind cant process that, we are not smart enough
There is a bird in the camera that etches the picture in stone.
Well I think there is a chip and batteries power the chip so the falsh goes off?
go to wikipedia, and type in camera, do some reading. its jus like our eye.
the camera is ALIVE...is paints pictures and can even do self potraits!
