Hi Beth,
I¹m new here at APG but this is one area I can help you with. As someone
else stated jpg files are smaller files but you will lose image data in this
method. Another thing I want to clarify is when you say bitmap, are you
saying a .bmp file format - as opposed to a bitmap color file? These are two
different things. While .bmp files are popular in the pc world, mac
computers don¹t use them much ‹ it¹s a Window¹s thing. There is a bitmap
color setting (which is only black and white) when you scan and that is
something different. I wanted to clarify which bitmap you were talking
about. The pc/mac thing may not make a difference to you, but I wanted you
to know that there are differences.

When designers get professional ³hi-res² scans this is traditionally the
* Keep the file in RGB color mode (your scanner may say thousands of colors
or something to that effect)
* never scan the photo/image less than 100% or go larger than 300% - even
200% really, you¹re better to up the dpi (see next bullet)
* keep the resolution (dots per inch or dpi) at least 300. You really only
need 200 for a good print off most desktop printers but since you¹re
probably never going to see these items again, and if at anytime in the
future you want to print them bigger or in a book, you¹ll need that 300 dpi
* Save in a .tif file if possible. A .bmp file is also fine as it is
uncompressed ­ just make sure you¹re not in the bitmap color format. The
.tif or .bmp files will be significantly larger files then you¹re probably
used to. Burn them to cd¹s for back up or on an extra hard drive if you¹re
worried about space.

Your last part about the plastic sheet protectors: it depends on your
scanner. Some scanners may pick up a glare and other¹s won¹t ­ as other¹s
have stated you probably want to experiment a little.

Another note, clean the glass on your scanner well and make sure it is dry
before scanning. You don¹t want some random hair or dust spot on these great

If there¹s anything else I can help you with please let me know.

Subject: [APG] Scanning Letters

As of yesterday, I have in my possession temporarily a number of letters
written by my 3rd great-grandfather and other members of his family. I
would like to scan the letters before returning them to the distant
cousin who so graciously sent them clear across the country so I could
see them after receiving the history I wrote on this common ancestor.
Could those of you who are better at this than me suggest the best kind
of image to save them as. The one I have experimented with was saved
as a bitmap image, but would a .jpg image be better?

The letters arrived in plastic sleeves and my intention is to scan them
through the sleeve unless they have been folded and are longer than the
size of the sleeve. Will this affect the quality of the scan?

Thanks for any suggestions. I'm thinking this has been discussed
before. If so, could some one refer me to the name of the topic so I
can find it in the archives.
