Converting color bitmaps to B&W

[charliescoffee]

I saw a tutorial about this somewhere, but I have some color bitmaps I’m trying to convert to black & white. Can someone point me in the right direction? Thanks!

Click on the search link at the top of this page, type "contone" without the inverted commas, you'll find everything you need to know.
Saludos,

Yep, simple. Thanks, Bob!

You can also use the Photo Tool (P) and set the Photo Saturation slider to -100.

That reduces the amount of color saturation to 0.

Marvelous!

That's just ticket I wanted!

To get a real "tone" to the b&w, don't you pull more from the red spectrum or what not? I've seen tutorials on photoshop regarding this, is there a Xara equivalent?

Many Photoshop canned plugins use a simplified (non-threatening) interface where you adjust the "look" of your B/W photograph based on a "slider" of colours... BUT the core of the operation is what Sledger described here: http://www.talkgraphics.com/showthread.php?t=35456

It's the same thing.

Could you post a link? I can't really see what else there is part from Red Green Blue and and adjusting the levels for each channel? That's the only data that's there, no?
