The process of traditional photography is

The production process is different: as a photographic tool, the appearance of a digital camera is basically similar to that of a traditional camera, except that the traditional camera uses silver salt photosensitive material, that is, film, as the carrier, and the photographed film has to be developed to get photos. Just after shooting, the operator can't know the quality of the photos, so delete the bad photos. Under normal circumstances, the effect of photos processed in darkroom cannot be changed. A digital camera uses a charge coupled device (ccd) to sense light instead of film, and then converts the light signal into an electrical signal, which is recorded on a memory card after analog-to-digital conversion. The memory card can be reused. Because the photos taken by the digital camera need to be digitized before being stored, the photos taken can be played back and viewed, and the dissatisfied photos can be deleted immediately and re-taken. Connecting a digital camera to a computer after shooting can easily transfer photos to the computer for various processing, and then print them out through a printer, which is the main difference between a digital camera and a traditional camera.

The shooting effect is different: the silver halide film of traditional cameras can capture continuous tones and colors, while

The ccd element of digital camera will lose some details in dark or bright light. More importantly, the pixels of images captured by ccd elements of digital cameras are much smaller than those captured by traditional cameras.

. Generally speaking, the resolution of traditional 35mm film is 2500 lines per inch, which is equivalent to180,000 pixels or even higher, while the ccd of a better digital camera can only reach10,000 pixels or more. At present, the photos taken by digital cameras are not comparable to traditional cameras in terms of clarity, texture, level and color saturation.

Shooting speed is different: you need to wait 1.5 seconds before pressing the shutter, that is, before the digital camera actually records data. This is because digital cameras need to adjust the aperture, change the shutter speed, check the autofocus and turn on the flash. Every time a digital camera takes a photo, it has to wait 3-7 seconds to take the next photo. This is because digital cameras have to compress the photos they take and store them. Due to the slow storage speed of the memory card, the shooting speed of the digital camera, especially the continuous shooting speed, can't meet the requirements of professional photography. Moreover, because every action of the camera needs power consumption, the power consumption of digital cameras is large. These are the shortcomings of digital cameras.

The storage media are different: the images of digital cameras are digitally stored on magnetic media, while the images of traditional cameras are chemically recorded on silver halide films.

There are different input and output methods: the images of digital cameras can be directly input into the computer for processing and printing. The image of a traditional camera must be developed in a darkroom. If it is to be processed, it must be scanned into a computer by a scanner to get a scanned image.

Image quality will inevitably be affected by the accuracy of the scanner. In this way, even if the original quality is higher, the scanned image is far from good.

Digital cameras can easily capture all the moments in nature as digital images for computer direct processing and display on TV, so many computer or home appliance manufacturers, such as Hewlett-Packard, Sony, Apple and Sharp, are competing to produce digital photos.

Machine, it is no longer just Kodak or Fuji photographic equipment factory franchise products. At present, several Japanese photographic equipment companies are trying to eliminate silver bromide films. Many multinational companies compete for the digital camera market precisely because they see the outstanding advantages of digital cameras, that is, it can benefit users in terms of speed, convenience, reducing the cost of pictures and improving efficiency.

It can be predicted that with the further development of science, the imaging difference between digital cameras and traditional cameras will become smaller and smaller. In the civil field, it is an inevitable trend for digital cameras to replace traditional cameras!
