RE: [genphoto] what file size and type?
- Scan so that you'll have a minimum of 150ppi at your final printed size (300
is better). That is, if the original is 4x6, and you want to be able to
print a nice 8x10, that would double the ppi you need (pixels per inch), so
you'd scan at 300-600ppi. JPG can be used for CD storage as long as you have
the quality setting set at maximum.
For the 'keeper' files, TIF would be preferable to JPG. Scan at the highest
resolution that makes a filesize you can handle easily. 25-50 megs per file
is not unusual. This will guarantee you can do whatever you'd like with the
images in the future.

- Large images are fine for archival size copies printed one page at a time.
What size do you recommend for genealogy box charts for wall displays or
descendant charts in book format that could have dozens of images? How about
genealogy scrapbooks or word processor files with sets of pictures and
Some researchers keep four copies of each image -- archival, family
scrapbook, web and thumbnail sizes. Some owners of older digital cameras
were quite happy with life size posters printed from TIF files converted
from 900 kb JPG. A newer digital camera might be 3.25" x 2.75" x .75" with a
3x Optical Zoom.
One option is to crop parts of source images, for example the household
names and main details from an oversize census page printed from microfilm.
That way relatives can see the handwriting from 1861 - 1901 Ontario and make
their own evaluation of the spelling of the family names. Location and page
details can be included in the caption.
One person had to use the master document feature of her word processor
because a family book with pictures could not be printed from a single word
processor file. Other researchers use page holders for multiple word
processor files for picture pages.
How many pictures could be included in a box chart or word processor file if
the originals were 4x6 and scanned at 600ppi? My older printer used to shut
down in the middle of a picture if I tried to print too many pages at once.
A typical family book page (using Word or similar) is about 6 inches wide
and 8 inches high. I've never attempted to print more than 50 pictures with
a single Word 2000 file, so that meant splitting a book into four files of a
few chapters each. Two pictures per page with detailed captions was probably
the most common layout.
