    help turning an image to just balck and white...no greys


    can some one tell me how to turn a regular photo into one that looks like one of the following? With it being just balck and white with no greys. I can do a half assed job of it but the image looses most of it's definition.
    also is there a specific name for this kind of photo manipulation?
    thanks

    To get better control, change your image to
    greyscale then up the contrast and fiddle with the brightness
    until you get a reasonable result.
    If you're loosing too much detail have a bit of grey in there and then save it as a two colour indexed image with dithering to get the detail back, but keep it purely black and white.

    Those images both have a little gray in them... note the smoothness of the areas between black and white.

    To completely get rid of anything except black and white, convert your image to grayscale and then convert it to bitmap at the same resolution. No more grays at all.

    Otherwise, desaturate it completely and mess with the levels.
