What are the advantages of digital cameras compared with traditional cameras?

First, the difference between digital cameras and traditional cameras

1, different manufacturing processes

Traditional cameras use silver salt photosensitive materials, that is, film as a carrier. After shooting, the film has to be developed to get the photos. You can't know whether the photos are 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. After shooting, you can directly connect to the computer, and you can easily transfer photos to the computer for various image processing, making web pages or printing directly, which is the main difference between digital cameras and traditional cameras.

2. The shooting speed is different

Before pressing the shutter, the digital camera needs to adjust the aperture, change the shutter speed, check the autofocus and turn on the flash. Digital cameras need to compress and store images after taking pictures, which all need to wait for 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 under dark light or strong light. More importantly, the pixels of the image collected by the CCD element of a digital camera are much smaller than those of the image taken by a traditional camera.

4. Different input and output modes

Images of digital cameras can be directly input into computers, printed 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

Images of digital cameras are stored in digital form on magnetic media, while images of traditional cameras are recorded on silver halide films chemically. 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.

What are the advantages of digital cameras?

1, the biggest advantage of digital camera is that it can digitize information. Because digital information can be transmitted in real time through digital communication networks all over the world, digital cameras can transmit images in real time first.

2, the digital camera can shoot and watch immediately, and the effect is immediate.

As long as the memory card of digital camera is large enough, it can shoot a lot. If you don't need to output, there are basically no consumables, which saves considerable expenses. You can press the shutter without hesitation.

4, easy to save, 30G hard disk can store at least 450,000-70,000 3-megapixel photos.
