KAT -
You need to READ the LOC entries above and below the site listed so that you understand...
1. Preservation Quality
2. Images and digital Tonal aspects.
By the time you have your "originals" scanned ...and then scanned again for publication by a "book-company" your archive quality is SHOT!!
PLEASE....take a 15X magnifying glass (jewler's eye-piece,)to a "nice publication" photo - say "TIME Magazine" to your unaided eye it looks great...under the glass....it is crap....
While you have the "glass" in your hand....look at the screen of your computer monitor.....WHOOAA!!!! it is little three colored triangles.
Sincerely,
Gargoyle
Take a photograph of a picture on your TV monitor and THEN view it after processing!!!!!UGGGHHHH!
