I am planning to include at least one DVD with the next edition containing
good images of certificates. I think collectors would love to see images
of scarce and rare certificates. I would also like to include images that
illustrate minor differences between varieties.
How
good do images need to be? A good rule-of-thumb is that scans should be good enough to read printers' names. I have compiled a substantial amount of information about Scanning Certificates.
Scanning suggestions.
- Scan in full color
- Scan against a white background
- Minimum resolution 200 pixels
per inch
- No reduction (see note
1)
- Scan entire certificates (full borders)
Do NOT scan
Hints for scanning certificates too large for your
scanner
- Scan in two or more pieces
- Always keep the same orientation for all the pieces
- Scan pieces with at least 2 " of overlap
- Remove the lid of your scanner
for delicate certificates
- Send the pieces (I will
patch together)
- Read Scanning Large Certificates for more information.
Save format
- JPG or JPEG. Save at medium high level quality. No need for highest quality.
- TIFs are okay but create much
larger files.
How to send
- If sending a few JPGs, send as
single e-mail attachments (no need to zip).
- If sending TIFs or several JPGs,
send via WeTransfer.com
Note 1
Many people genuinely think they are
sending high resolution images, when in fact they are not.
This is because they reduced their images while scanning. See Reduction during scanning to see real-life examples of the problem. The easiest solution is to avoid all reduction.
