u can try tracing it with adobe illustrator :s with the pen tool

Theres a tutorial in the resource section that will help you out with that. I've seen a few of them... It's really easy in photoshop.

Sort version

Use "levels" to get the right amount of solid black lines
Use "Channels" then "Load channel as selection".
Then lock the transparancy on the layer and run over the image with the eraser tool

That's not exactly how but the general idea.

Another way is to set the layer mode to darken or multiply then you only see the black lines shown above the layer below it.

* short version

Setting the layer mode I found works better and takes less time. AND no white pixels are left behind like the other way could.

"Put the sketch on its own layer in Photoshop. Set this layer to "Multiply" in the Blending Options (next to "Opacity") on the Layers Palette. This will allow only the dark areas of your sketch to show over the color later on, and will automatically mask out the white parts of the sketch."

This is how I was told to do it, and it seems to work rather well, though I, by no means, am very good at it.

I hope that helps at least a little.

Photoshop has a pen tool as well, which works mostly the same.

*lemontea has a nice tutorial on doing this (the process is called vectoring) [link]

Another thing you could do is Select> color range with selected color, and click on a white in the picture. then mess around with the fuzziness until it's to your liking.

Vectoring is a lot of effort, but well worth it.

Most people set their lineart layer to Multiply mode, but a better way to do it is to do the Channels trick:

1. Scan your lineart in greyscale mode.
2. Clean it up by adjusting the levels.
3. Erase trace debris and smudge marks that don't disappear with the levels adjustment with a hard-edged eraser .
4. Click the Channels tab (it's next to your layers tab by default) and Ctrl-click the Gray channel (it'll be the only channel in there)-- doing this selects all the white on the canvas.
5. Click back to your Layers tab and hit Ctrl-Shift-I to invert the selection (alternatively, you can go to Select--> Inverse to do the same thing).
6. Create a new layer.
7. Hit Alt-Backspace to fill the current selection with your foreground color, which should be black (or Ctrl-Backspace to fill with your background color).

Following these steps should leave you with your black lineart cleanly seperated from your white background.

Those directions cater to people with a decent amount of PS experience. If you have any trouble, feel free to Note me and I'll send you some screen shots if you like.

On the line art layer, go to channels and click the dotted circle, delete, inverse select and go over the selected lines with a big black brush. Then make your layer a multiplied layer.

Oh! And as always, clean it up if needed.
