Who wants to help a brother out?
I'm looking for a much easier way to turn an image from color to black and white, where the white is white, no grey scale, and the blacks are preserved. SO, for example, the lower image, I want all that brownish tone gone and just the black lines left. No greys, just a solid black and white.
I've found an incredibly long and tedious way to get it done in GIMP, but I was hoping for a simpler more expedient way.
Gracias, in advance.

edit, you have to make it gray scale first.

What I've done in the past was: boost the contrast, convert to black and white and then use the bucket fill to fill in the rest of the grey to white. That's the tedious part because you have to keep the threshold low enough not to detract from the black which means it will only change a little at a time and some of those grey areas change from pixel to pixel. And, as you can see, there's a lot of small areas in there.
Curtis Edenfield I'd like to figure it out myself, but may take you up on your offer sooner or later.

I was kind of hoping for a way to use the color selector, select a "grey" area and then either swipe it out for white or "erase" the color with the eraser, leaving only white.
For what it's worth, I'm trying this in GIMP, but I also tried it in Paint.NET which is a more basic image editor than GIMP. I have other - photo manipulation - programs available but none of them are PS.
I begin by raising the contrast of entire image until the content I want to keep either begins to fade or get covered up by darkening artifacts then I back it off a couple steps.
I then convert it to gray scale and use a selection tool to make a box around problem areas and adjust brightness and contrast of it independently until it matches surrounding areas.
I then continue upping over all contrast and brightness correcting artifacts along the way until upping contrast does nothing more.
If all goes well you should have image close to or better what I have posted.
for images with colors too close together over all, I try to use the gray scale images from separate channels and then combine the ones I that worked decently to get an acceptable image,

With the screen cap, I got the same results, still pretty dirty. Resolution is King. any thing over 2 Mega Pixels. At 5 MP it would take me a few minutes to tune out those dirty spots where the cresses are.
2) Desaturated it to remove any color shading.
3) Added Artistic filter Cartoon, This thickens the lines.
4) Threshold, Lowered, to remove the heavier contrast spots.
