- I would like to do some comparative testing of the results from scanning
- old photographs. I need help from the net as to what makes sense.

- [THIS IS A TOPIC THAT HAS BEEN ADDRESSED BEFORE AND GETS ADDRESSED EVERY YEAR
- OR SO... SO ONE CAN LOOK BACK AT NET LOGS AND READ LOTS OF GOOD DISCUSSION ON
- PRESERVATION OF PHOTOS WITHOUT REGENERATING LOTS OF NEW TRAFFIC]
-
- However the issue for me right now is to see if I have a decent grasp of the
- parameters before asking a niece with access to scanners of different varieties
- to do a test for me.
-
- Parameter one... It would seem that one thing I will want to do is give her
- a large photo and a small one to test scanner resolution.
-
- Parameter two... It would seem I need some way of figuring out if there is
- something about the software (as opposed to the scanner itself) that makes
- one or the other scanner work better.
-
- Parameter three... File size of the created image might be important. Storage
- is one consideration... but probably more importantly the better scanners with
- better resolution will probably be storing each photo as a larger file.
-
- Parameter four... Which graphics standard is the photo stored in and which
- package would I wish to print it out with? I am aware (only slightly) that
- the graphics arena has several different standards and translations among
- them generally lose stuff from the original file.
-
- There I've shown my ignorance and as I read the list ... these really don't
- seem to be parameters but just a list of things. Can some of you help me
- through this? My sense is that many of you in the biological sciences are way
- ahead of me in playing with images\graphics. It has been my impression that
- it is the optical part of the scanners that inevitably falls short of making
- scanning a reasonable thing to do, but that the day will soon be here that
- we can pull together our family albums electronically.
