What's the difference between a digital camera and a traditional camera?

As a computer input device, digital camera is similar to ordinary camera in appearance, some functions and operation, but it is still different from traditional camera. So what's the difference between a digital camera and a traditional camera?

1, the manufacturing process is different: traditional cameras use silver salt photosensitive materials, that is, film as the carrier. After shooting, the film has to be developed to get the photos. After shooting, you can't know whether the photo shooting effect is good or not, and you can't delete bad photos. Digital camera uses charge-coupled CCD element to sense light, and then converts the light signal into electrical signal, which is recorded on the memory card after analog-to-digital conversion. The memory card can be reused without submitting a paper. After shooting, you can play back the viewing effect or delete the photos.

2. Different shooting speeds: Before pressing the shutter, the digital camera needs to adjust the aperture, change the shutter speed, check the autofocus and turn on the flash. After a digital camera takes a picture, it is necessary to compress and store the captured image, which takes a few seconds. The shooting speed of digital cameras, especially the continuous shooting speed, cannot meet the requirements of professional photography.

3. Different shooting effects: the silver halide film of traditional cameras can capture continuous tones and colors, and the photos taken by digital cameras are incomparable in terms of image clarity, texture, gradation and color saturation. However, the CCD element of a digital camera will lose some details in dark or strong light, and more importantly, the image pixels collected by the CCD element of a digital camera are much smaller than those taken by a traditional camera.

4. Different input and output methods: the images of digital cameras can be directly input into the computer, printed and output after processing or directly made into web pages, which is convenient and quick. The image of a traditional camera must be developed in a darkroom, and it must be scanned into a computer by a scanner for processing, and the quality of the scanned image will inevitably be affected by the accuracy of the scanner.

5. Different storage media: the images of digital cameras are digitally stored on magnetic media, while the images of traditional cameras are recorded on silver halide films by chemical methods. At present, the storage media of digital cameras mainly include SM card, CF card, XD card, SD card, MMC card, Sony memory stick and IBM small hard disk.

The above is the introduction of the difference between digital camera and traditional camera. I hope it helps you.
