Scanning Photo Negatives - DIY Solution?

Discussion in 'Scanners' started by Michael Goodwin, Nov 20, 2003.

  1. Hi,
    Can anyone advise a "DIY" method to scan 35MM photo negatives?
    a) description of physical arrangements
    b) advise on best Twain/Scanner settings
    c) tips on approach to color management using any graphics software

    You may not want to hear the good answer, but this problem has already
    been solved, and you should acquire scanner equipment actually designed
    to scan film.

    On a flatbed, this job has these major components:

    1. Provide diffused florescent light source above the film.
    2. Calibrate the individual CCD cells to that light source (instead of
    to the lower reflective lamp that it now calibrates from).
    3. Disable the lower lamp that will reflect from the film.
    4. Filter out the orange mask of color negatives.

    1. is at least conceivable. This the only requirement that some users
    imagine, but there is much more to it.
    2 is impossible unless you can also modify the scanners firmware and
    software to do the job. The manufacturer can do this, users cannot.
    3. if you simply disable the lower lamp, current calibration that it
    expects to complete will fail, and the scanner should refuse to start.
    Again, software changes are necessary.
    4. is normally done with longer exposure times of the green and blue
    channels (analog, and controlled by software again). It's very drastic
    to do this right after it is a digital image.

    Any cheap flatbed with real TMA will do a vastly better job on film than
    any kludge attempts that dont address 2 and 3 and 4.

    But not too cheap, a better flatbed with TMA will be better.
    And a real film scanner will noticeably be best of all.

    Playing around is one thing, but if you have much film to scan, and/or
    have higher quality standards, a real film scanner is definitely

    Until I got my Microtek 5900 I used the following technique
    I know there are those that do recommend this system, however at 2AM and
    you need to convince a client you need a REAL scan or for newsletters it
    does work.
    Have fun.

    the wat I do it is:: I purchased a microtec neg/slide adaptor ( around
    25ukp ) which is a sort of light box , place neg/slide on scanner light box
    on top, switch on light box and scan. you need to do a little adjustments
    after like reversal etc but no problem.
