The picture is scanned by a scanner or taken by a digital camera. Is there a difference between the two?

There are differences, sometimes very different.

1, when taking pictures with a camera, it will be affected by the external environment, especially the light, and the light will be uneven. Generally speaking, the photos taken with cameras have a low degree of reduction; When scanning with a scanner, the photos are operated in the scanner and are hardly affected by external light. If the scanner has high precision, the picture will be highly restored.

Taking pictures with a camera is fast, but it usually takes a long time with a scanner. If the accuracy is high, it may take tens of minutes.

3. When scanning a picture with a scanner, the size can be reduced from 1 to 1, while when using a camera, it is generally smaller.

4. If the picture is larger than the scanner, the scanner can scan this part and then use software to splice it, which is difficult for the camera to do.
