Should I scan all pages of an album at the same size (dimensions)?

    A pretty basic question...more related to workflow

    I am scanning all of the pages of a very old photo album, and some of
    the pages have crumbled enough that if I wanted to minimize the area
    that I scan, the scans would vary in size from page to page (some
    pages are now slightly smaller than others, though they all years and
    years ago were the same size).

    What I would like to do in the end is either show the scanned images
    on a TV (via DVD or AppleTV), or print out as a book. What I am
    wondering is, should I make sure to scan all the pages in at the same
    size? Will that make it easier to ensure that the size of the images
    that I either print or show in the end remain the same (relatively)? I
    think the answer is yes...

    Like if there is a slideshow on my TV, I would desire all the scanned
    pages to all show up "magnified" by the same amount?

    Thank you!

    Scanning for computer or tv "slide shows" and scanning for printing
    require far different scan resolution.

    Typically, one scans for archive (highest reasonable resolution) and
    then derives print image from the archive and the web/tv/computer image
    from the archive or the print image.

    A full page print can be held at reasonable resolution assuming 150 dpi
    for the printer. 8.5 x 11 becomes a 1275 x 1650 image. At 300 dpi,
    just double those numbers. As you can see this gets to be a pretty big
    image.

    OTOH, for screen display, and image of 800 x 600 to 1200 x 900 (whatever
    proportions you need) is quite a bit smaller.

    For television display (NTSC) quite a bit smaller still.

    www.scantips.com would be a good place to learn the basics (and then some).

    Cheers,
    Alan.
