What are the classifications of scanners?

There are so many kinds of scanners in the market, how to choose the right equipment. In fact, depending on the use and positioning, these scanners can be divided into three categories.

　 1， Household

famous models are:

EPSON epson V7/75/8

Canon canon 88F/9F

Nikon Nikon 9d/5d/VED

lean optical film 82/72/ 12

Minolta Dimage Scan

Both Canon and EPSON are flat-panel scanners that take care of negative scanning, while Nikon, Lean and Minolta are specialized negative scanners with lens focusing structure. The former is less sharp than the latter, but it is easy to use. The latter belongs to fever equipment, which can have good image sharpness.

most household scanners are equipped with infrared ICE dust removal, which can shield dust particles or even scratches falling on the negative during scanning, saving a lot of time for retouching. However, it takes a long time to scan out good photos and a certain post-color matching technology.

2, the printing level

The big machine in the printing era, the famous models are:

Fuji FUJIFILM SP2/3

Noritsul LS-6/LS-11/HS-18

Minolta DS-2e <. They have the same characteristics, that is, fast and easy.

apart from efficiency, the imaging performance is even worse than that of some household scanners. However, commercial operation is not about the details we photographers care about and the transition. But whether it is pleasing to the eye for most ordinary guests to get photos produced by these machines. (The situation can be compared with the popularity of self-timer artifacts in Eastern Europe)

Therefore, every printer scanner has its own unique color processing curve, which makes ordinary photos very tasty, that is, fans are familiar with the taste of film.

besides, commercial machines emphasize simple operation. As long as the relevant training courses are provided, an ordinary person, as long as he is not weak in color, can be trained and employed within half an hour, and can make decent photos within 1 minutes.

3, industrial

The famous models are:

Heidelberg Primescan 39/71

Imacon Imacon Flextight /848/949/X1/X5 (merged with Hasselblad in 23)

Kodak iQsmart 1/2/3

. In the film age, almost every magazine and poster can't be separated from these scanners.

they all have unparalleled performance, and can dig out every detail on the negative. Therefore, there is no infrared dust removal function, and a clean production environment is needed. After the default output, special post-color correction processing is needed, and the whole process requires high technology. In the end, I might as well flip through the old photography magazines published 1 years ago. In the era when there was no digital camera, most of these clear and exquisite photos were like this.
