    Cleanup of yellowed images

    I am using Irfanview 4.2.5 to clean up 19th century images like the one here: http://en.wikisource.org/wiki/Page:P...ume_2.djvu/801. The original was taken from a JP2 web image of several MB from the Internet Archive. The problem is cleaning up the tiny spaces withing the characters. It's a very long process and I have many images. Is there a quicker way to clean them, other than each individual character with Irfanview or do I have to change to a different software?
    Thanks for any help.

    With pictures like this, a lot can be done with "Decreasing Colors".
    With maybe an additional editing of the final palette.

      IrfanPaint (F12) and colour replacer with a large brush and high tolerance setting also does a quick job.

        I would try Image> Colour corrections and set Saturation right down (-255) and Contrast way up (~100).

        You could also experiment with other features like the "Yellow eye reduction" in Image> Effects >Effects browser.
