will someone please submit a method for creating the 2 color photo effect as seen on the right side of this web page: http://www.nealpollack.com/
You might be looking for THRESHOLD. Just go to Image>Ajustments>Threshold (I think.) I don't have Photoshop open right now, but let me know if you can't find it.
There is an after market filter called Fiter Factory. you want H15 "print screen" you can use this with a gradint map to get the effect your looking for.
Here it is. (http://showcase.netins.net/web/wolf359/files/ffhgalpc.zip)
There is a filter already built into PS7 that creates this effect, so you don't need to get a third party filter. Read the photoshop doc to see which one it is.
