Ahhh, NOW I understand that sentence! ;) What happened is, that my pixel values (=luminance) were around 0.1, which created a surface plot of the height of around 0.1 pixels, i.e. : flat. Thanks for making it click! But maybe one could improve the description of the z-scaling a bit better, improve clarity and maybe to include this little number example with 0.1 as pixel values? I have the feeling it would help all newbies to understand how to do the scaling.
