Hi Craig !

From the explanations and the tutorials FOUND HEREin the Tutorials Forum, it is like you say an image used to "transmit" its characteristics to another --sort of a symbiosis type of thing

What I find tricky is how to make a displacement map. It is not simply use an image and convert to black and white. It is well described in the tutorials I mention above. Perhaps is similar to the "apply image" in Photoshop. I don't know if PSP has a similar function.

Hope it helps ?

Regards - Martha

A displacement map is a grayscale image that is used in the Displace filter in order to displace (shift) the pixels in the target image. White displaces pixels toward you and black displaces pixels away from you. The horizontal and vertical direction of the shift can be adjusted in the filter.

It's the equivalent of using a bump map in a 3D app.

In Photoshop it's useful for making images appear more realistically applied to an irregular surface like rock, old wood, a wrinkled shirt, etc. When you just use a blend mode on the image you want to apply to such a surface you don't get the kind of distortion that an image would really have if it bent around folds or dipped into cracks and crevices. Using a displacement map accomplishes this.

racc,

sounds a lot like when we used to use grayscale images to make height maps, only a different application now.

thanks

Just a note to say

Thanks for the link.

I have been to that site before but never noticed that excellent tutorial (Or Maybe I just was not ready for it)

I did google searches for displacement maps but did not find this one.

This will keep me busy for the next couple of weeks.

Thanks

Ken
