Since I am fairly new to all the expert ways of scanning, I wanted to say that this list has already been extremely helpful to me - a great resource, thanks! I was also wondering if one of you could explain to me the difference between Group 4 and uncompressed .tif formats, and what the impact is on quality, size, etc. Which is the preferred format, if any, in your opinion? Thank you in advance, Irene Peters

How do you plan to *use* the images? Try a full project scanning pictures, adding to a family book report or web page, adding details about the pictures to the files and reprinting or update a web page. My largest single word processor file has 50 images and largest family database in FTM has 750 inserted pictures. Usually save JPG images of family pictures scanned to the size for a specific purpose. Uncompressed TIF images are large files if you need to share attachments to e-mails. My favorite image software doesn't refer to Group 4. Uncompressed TIF images are sometimes more efficient than high quality JPG for source documents with limited colors. Some genealogy programs allow uncompressed TIF and some don't allow TIF at all. One archival size copy of each image is not enough. Plan organized sets of images that can be backed up as the organization changes over time and newer copies of backups sets are stored in remote locations.
