Hi everybody,

I did 3D surface plot in two of my images from 8 bit CCD camera. I use display colors in LUT. But I couldn't set scale in Z axis which is the height for the image.  I'd like to campare the heights of the two images from this 3D plot.

So I went to documentation of ImageJ for help. I found there 'The luminance of an image is interpreted as height for the plot.' Now my question is how can I scale the luminance? What is it's unit? Is it start 0 and end 255?

Can anybody give me idea?

Thank you all.
