Hmm... Strange one. But here's a quick way I might do that.

Select > Colour Range > manually select the saturated colour areas using the +picker tool and adjust fuziness.

Once you have the selection you can modify (in select menu) it with smooth, expand, etc.

Any good?

I have just found a way you could do it.

Take your image, set the layer to "saturation"

Place a layer below that is a pure RGB, for example pure red.

Now you can see the areas that are more saturated than the others. I think this is what you are after. You could collapse the layer, desaturate it and you would have a mask of the saturation... I think.

stinger- yeah thats usually a pain in the complete ass to do well...and well the info is there so...

bad spleen...perfect...cheers

final method:
-make layer "saturation"
-add red layer underneath
-in channels select red with ctrl click on thumb
-create new layer add selection as mask, fill layer with white
- add black layer beneath
-level mask to taste
