What are the advantages of digital cameras over traditional cameras?

(1) To digitize the images taken by traditional cameras, we must go through three steps: photographing, developing and scanning. However, photography with a digital camera does not require film, darkroom or scanner. The captured image can be directly input into the computer and displayed on the computer or TV. Users can edit and process images in computers, output them through printers or send them to others by e-mail, which greatly improves work efficiency.

(2) You can't see the effect immediately when you take a picture with a traditional camera, and sometimes you can't take a satisfactory picture after taking a whole roll; On the other hand, digital cameras realize what you see is what you get-you can see the captured image immediately, and if you are not satisfied, you can delete it immediately and make room for reusable storage.

(3) Traditional cameras need to buy films constantly; The memory of digital camera can be reused, which is very economical.

(4) Ordinary negatives and photos will be mildewed and the images will deteriorate; The photos taken by digital cameras are all in the form of files, which can be copied indefinitely and preserved permanently without attenuation or distortion.

(5) Traditional cameras cannot be used as image demonstration equipment; Most digital cameras have video output function and can be used as image demonstration equipment.

The above advantages of digital cameras, coupled with the popularity of computers and networks in recent years, have made them more and more popular among the public.
