Scanning of stamps
Working with scan
The key is to start a scanning in a high resolution. I have good experience with 600dpi or 1200dpi. Most scanners have a standard 200 or 300dpi, but it's my opinion too little for a good quality scanning of stamps. The high resolution give a very large file, but most programs can handle it. Try 600dpi.
When you do your first scan of a stamp, it is important to store it in an original format eg. as TIFF because in this format all information about the scan will be saved. If you are using JPG format instead you will loss some of the information, and when you are working on and on with the scanning, you will loss more information each time the file is compressed.
The size of a scanning of a stamp in tiff format is app. 1mb. A scanning of stamp or stamps in 600dpi and saved in TIF format, gives a super quality.
Sending a scan
When the image is used for webor sent by e-mail, is JPG format ok.
Customize the image to a width of 475pixels or 950pixels - that's the size I use on the Internet (fourblock is 950pixels wide). The image is compressed to fill app. 200kb, but they can actually compress more without losing much on the computer.
Remember to name your scans with something meaningful and avoid the danish letter æ, ø and å and ( , . / \ ) in the filename.
Ex 1:25ore-pr10-p98-ofxx.jpg is a 25 ore, print 10, pos.98 with a unknown OF. Ex 2: 25ore-prxx-pxx-of11.jpg, is a 25ore, print unknown, pos. unknown, but with OF.11
Hope it makes sense.
