How does a digital camera work vs. a manual camera?

Question

Let me explain:
I know that the shutter speed/aperature effect the way the light hits the physical film, but on a digital camera, they have the same settings, yet there is no film to expose to light. What's the deal with that? How does a digital camera work, exactly, and why does it have the same settings as a manual eventhought it doesn't actually expose ANY true film?

Answer 1

With a 35mm film camera, you'd set the aperture and shutter speed, focus, record the image on a frame of film and advance to the next frame.
With a digital camera, the image is captured by a digital sensor instead of film, and instead of advancing the frame, the picture is sent to a memory card.
Only the way the image is recorded and stored has changed. Aperture, shutter speed, etc. still work in exactly the same way.
Leica really proved this point making a digital back that you can attach to their existing film cameras. You simply remove the back panel (and the roll of film) and attach a different back panel with a sensor and memory card instead.

Photons is the way light travels. The debate of whether it is a wave or a particle is a technicallity but as a suggested way to picture the photo process let's pretend each photon is like a student.

Light is like a school letting out the students. A gate is like a shutter and the amount of students can be controlled by the size of the gate or like an F stop.

Each "student" will in a film camera change the silver iodide molecule to be noticed in the negative. The negative in turn has to be processed to become a picture.

A "student" in a digital camera will excite the receptor and that is recorded as a pixel on a memory ,medium. When the picture has to be recalled to form a picture, a formula or set pattern is used to interprete the plus and negative information that will translate into a picture.

Answer 4

The difference is that digital zoom essentially crops the picture to make things appear closer. It reduces the size of the already tiny sensor making your files significantly smaller. It also amplifies noise and any other problems with the picture. You should never use digital zoom. Especially if you plan on printing any of the pictures. You need a lot more resolution for a good print than you do to view a picture on a computer monitor. Manual or optical zoom means that the lens itself zooms in and out. There is no cropping of the picture and it will not effect image quality or file size.

Answer 5

i heard that photographer teacher say that digital camera is not really camera??

i think the digital is some thing absorbs the pic
the pixels and form it into a picture
i like film camera better, i think the pic come nice and more natural

well i think don't explain much =/

Answer 6

Easy answer:

There is a light sensor inside the camera that captures the available light based on the settings you specify, then stores this image on your memory card inside the camera.

Answer 8

It uses what is called a CCD (Charge-coupled device) or a CMOS sensor to turn the light into digital images.
