    I posted the orignal message about how to use a digital camera to take
    pictures as if they are scanned by a scanner.

    The replier of this message said I have to rely on a stronger light
    source, which I don't have.

    He also suggested me to use Photoshop CS to process these images. I'm
    not a Photoshop pro and I don't even know how to convert a multi-color
    image into a monocolor image.

    Please refer to the following message body for detail.

    Could you help to fulfill my goal? Thanks.

    The easiest solution is to a hardware store and purchase two quartz flood
    lights. The broader the pattern, the better. Most HomeDepot type stores sell
    these for about US$10. Place these at 45 degree angles and equidistant from
    your artwork. If need be, you can hang a piece of white cloth as a diffuser,
    not too close to your light sources. This setup simulates a copy-stand. If you
    don't have a tripod, can't borrow, or rent one, then find a suitable support
    to brace your camera on.

    Another solution would be to wait for a cloudy day and take the artwork

    Both methods will require some color adjustment for color temp, should you
    decide to not process them to B/W.

    Rather than produce hi-rez poor images and try to reconstruct them in PS, you
    should attempt to improve the image in capture.

    This might not be what you want to hear, but it is by far the best solution(s)
    to your problems. Otherwise you are trying to re-invent the wheel via PS.

  3. Not completely sure what you mean by monocolor.
    If I want to change a fullcolour to a toned b/w image this is what I do:
    Load image, and choose image-adjustments-channel mixer.
    Tick monochrome. Play with the sliders until you have a decent
    well-contrasted b/w version of your image.
    This image still is in RGB mode. (I hardly ever use Grayscale to make a b/w
    image from a color version.)
    Add a layer, fill it with a colour, and change blend mode to Color. Play
    with the Opacity slider until you have a nice result.
