Since there isno adjustments category in the filter pallette in CS4, just how do you make a high contrast b&w? Chas

Chas,
Because I shoot in RAW, I usually use Adobe Camera Raw to convert to B&W. It can also be done using adjustment layers. There is a B&W adjustment layer or the Hue/Sat adjustment layer; contrast can then be increased using the curves adjustment layer. You can either adjust the curve manually or use some of the presets.
Chas, I think the nearest thing to a threshold adjustment layer is a gradient map adjustment layer like this:

You start with a standard black to white gradient, then put a black point around the middle of the graph, then a white one just right of the black one.
Then move both points right or left to get the desired effect.

Chas,
Based on CS3, there is a B&W adjustment layer available and you can click and drag (left/right) in the picture image to adjust the contrast of whatever colour is picked by the eyedropper when you do that - or you can adjust the sliders in the dialogue box to your hearts content.
I have a Scott Kelby method somewhere that he uses for "high-contrast" B&W, but maybe you could post an example of what you are trying to achieve.

Ahh,
Try (again based on CS3)
Image, Adjustments, Threshold
or
Wouldn't a Threshold Adjustment layer do the same thing?

Thanks,John. It's in the same place in CS4 also. Chas
