How does a digital camera work vs. a manual camera?
Jul 28, 2010 in
Electronics FAQs
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?

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.

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

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.

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 =/

The best way to answer this question is just to give you this link which will show you exactly how digital cameras work and the differences between a traditional camera and a digital camera:

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.
