    Use autoenhance (button in xsane main window) to get a good starting position.
    Then change gamma correction to get correct colors (contrast and brightness
    should be ok for the first tests, you should start with gamma).
    If you found good values save the settings (preferences->save device settings)
    and add a name of the negative type you used (eg umax:Astra2200-agfa-100asa-xyz.drc).

    Bye
