**               I am a Bryce 3d user and I want to make 3d clouds or may be clouds that resemble faces on them . Is it possible to make those sort of cloudy effect on the sky of 3d terrains with Photoshop ?? Please suggest ...................................I am attaching a sample face for you ........**

You could use a "bump" map (or terrain map), but the problem is that you have to define it with dark as the lower parts and white as the higher parts. In a photo like this you will have light coming in from one (or more) side(s). If you try to use that as a bump you will get high points where the hilight appears and low ground where the shadows are. In other words it will be a mess... (f.ex in your example picture the spec in the eyes would become high poles)

A suggestion is to ressemble a face close to what you want in f.ex. Poser or a 3D package. Export this to a format compatible with Bryce and texture it.

Now this is a challenge amlan!!! Wiseman makes a good point, applying a bump texture is the first thing that comes to mind. The problem he mentions is correct, yet it can be overcome. All depends on your knowledge of PS and how much work you want to put into this... In PS you could reduce the black&white contrast and remove the strong highlights by selecting and adjusting them. This may be a way to make the bumping work better... You could also try applying (one or two 'p's?) Treshold (Image; Adjustments; Treshold) and apply the b&w image as a bump, not sure about the result though... Last but not least you could make a cloud-like shape in Illustrator, open it in PS, apply Clouds to it (Filter; Render; Clouds), paste the face in it and use the eraser and Smudge Tool to make it blend nicely with your cloud in the underlying layer. This may be useless advice since I'm only brainstorming as I type this, but it might just be worth the try... Grtz
