Back and White with no grey scale

[ralex]

Is it possible to create a black and white image with no grey scale ?

Also is it possible to produce a black and white pen and ink facsimile with an artistic filter ?

I have been able to do both of these in the past on Photoshop with their artistic filter selection

No. This has been requested several times in the features request section. I suggest that you add your support  to the latest one.

You could use the Threshold Adjustment to make a black and white only image.

 

But that perhaps isn't what you want.

That is what I've been trying to obtain, how do you get to the "threshold tool"

[toltec]

Layer > New Adjustment Layer > Threshold Adjustment

 

Adjust the Threshold slider for the effect you want.

Another way?

Add a white rectangle over the entire image change the rectangle's blend mode to Contrast Negate

Thanks guys this achieves the effect I want, any thoughts on how to produce a black pen and ink facsimile and other artistic filters as in Photoshop

Here's one way:

 

Open the image, then duplicate the 'Background' layer. Uncheck the lower background layer in the stack to make it invisible. This keeps a copy of the original just in case, as the following two steps are destructive.

 

 

Make sure the top layer is selected, then pull down the Filters menu and choose Detect --- Detect Edges:

 

Now pull down the Layer menu and choose Invert:

 

 

Now add a Black and White adjustment layer and play with the settings until you're happy:

 

 

Final result:

 

 

 

I'm sure there are lots of other ways...
