    I'd like to have a 35mm color negative enlarged to somewhere around 20"
    x 30". Where can I have this done for a reasonable price?

    What is reasonable? My local pro lab charges $125 for a 20x30" print
    (includes the scan).

    If you can get a high quality scan yourself, www.ezprints.com will make a
    20x30" print for $17.95

    Regardless, a 20x30" print from a 35mm negative will look lousy from a
    viewing distance of less than a few feet. It will look fine if viewed
    further away (like 5-10 feet)

    For scanned negatives/slides and digital pictures, printing at 300 dpi
    produces superb results that can be viewed not only at noselength distance
    but with a magnifying glass. Dropping to 200 dpi doesn't seem to sacrifice
    much visual quality. Assuming even a reasonable viewing distance of a foot
    or two, I wouldn't want to drop below 100 dpi for anything critical. 20" at
    300 dpi is around 6000 pixels and at 150 dpi it's 3000 pixels. It's not all
    that hard to get a 3000 dpi scan of a 35mm negative, even from only
    moderate-prices flatbed scanners. As far as the scanned file is concerned,
    a 3000-4000 dpi scanner should produce acceptable 20"x30" prints from a
    full-frame 35mm original.

    BUT ... the digital resolution of the scan is not a measure of the quality
    of the original image! A medium-quality 35mm lens should be capable of
    resolving 50 lines/mm (at least at the center of the image). Since a 35mm
    original is only 24mm wide, that's a resolving power of only 1000 lines
    across the width of the image. That's only 1/3 of the digital resolution
    needed to get even a moderate quality 20x enlargement. Using anything
    faster than ISO 100 negative film or ISO 64 slide film sacrifices
    resolution. So does errors in focusing, camera shake/subject motion/etc.

    I've produced startling quality 20"x24" enlargements from 2-1/4" square
    Ektachrome originals and I'd estimate that the prints from similar 35mm
    slides would be at least acceptable for normal viewing. But those originals
    were produced on a 1st class camera mounted on a high-quality tripod, not
    hand-held with typical consumer-quality plastic stuff.

    If the OP wants to make a 20"x30" print from a 35mm original, a $18 print is
    probably about right for the quality of the final image. There are many
    mail-order places advertising in the back of Pop Photo who'll do that from
    either negatives or digital files.

    Any photo store in your area can take that order for you, maybe even
    Wal*Merde. Price will be from about $20 - $40. Don't expect miracles
    with the print from a negative that size.

  5. Get it done by Kodak. The thing will look half decent that way. Most of
    the more recent labs are not using the older gear and can't get the
    quality out of small negatives. Be very wary of anyone offering to scan
    the film and make a print.

  6. From the u.k.? I used Jessops - they did it very well.

    I enlarged a print to 30x20, from fuji reala 100 film, from a photo rested
    from the ground at f8, and a 35-70mm f3.5-4.5 pentax smc-A lens. The
    quality was really impressive - there were details you would never have seen
    from the usual 12x8 print.

    It cost between £12-17 a year ago, as far as I can remember.
