I've got the Nik stuff but have only used Color fx and Silver FX so far. Which program has the hot spot thingy in it?

Hi Judith, pretty well all of the Efex Pro 4 filters have it, if applicable.

This a pic of my trusty car, after its soaking at Ribblehead.

I applied a detail extractor filter to the black vent and the black rubber strip on the front bumper, the second image shows what the affected areas were by adjusting the size and intensity of the control point. The control point in the puddle is negative because the effect spilt over into the puddle, so that can be canceled out with a negative control point. In the second screen shot the dark areas are unaffected by the filter, the white areas are affected by that filter.

The image in Colour Efex Pro Detail extractor filter.



The image in the mode where you can see the effect of the control points. there is limited effect in similar shades and textures. That can be cancelled by placing minus control points. It really is good and very controllable, almost magic. No actual masking at all.

I could for example prevent it affecting the black headlamp surround by putting a negative control point in the brightest part of the affected area.
