Let's look at the difference between scanned photos and photos.

Scanning documents generally refers to digital photos obtained by scanning paper pictures with a scanner. Digital photos refer to digital photos taken with digital cameras. The image effects of the two may be different, but the essence is the same, both are digital pictures.

Digital photos can be converted into high-quality scanned photos.

Digital photos are the perfect combination of digital technology and photography technology. so-called

Digital representation is usually used in computer science and electronics, especially when real-world information is converted into binary digital form, such as digital audio and digital photos.

Signals carrying data are electronic or optical pulses, and each amplitude represents logic 1 (with pulse and/or high) or logic 0 (without pulse and/or low).

Digital printing refers to exposing a digital image on a silver salt color photographic materials through an exposure engine, and then developing it through chemical treatment to form a photo.

Printing a photo means printing an image on photographic paper with an inkjet printer to form a photo. There is a big difference between the two in principle. Printing photos is a process of chemical reaction, while printing photos is a process of physical reaction. There are essential differences between them. Here is their comparison:

Output quality

Professional digital printing mainly uses Kodak or Fuji's large-scale laser printing equipment, and the photos printed by these large-scale equipment are quite satisfactory in color, clarity and layering.

Photo printing technology has been constantly developing and improving, and now the printing effect is similar to that of large-scale laser printing, especially for some professional photo printers. Ordinary people should carefully distinguish the difference between the two.

Summary: The effect of laser digital printing is slightly better than that of photo printer, but it is difficult for ordinary people to tell the difference between printing and high-quality printing.
