Suggesting that the image may be a contact image?
According to Colin Berry who rendered this in ImageJ:
(Techie stuff: the height setting on the z scale was kept at 0.1, i.e. its default setting, one that cannot be reduced, as my embedded B/W reference shows, given it has no 3D history ,having been constructed in MS Paint. Minimal values were used for smoothing and lighting (10.0 and 0.2 respectively).
So what makes this image different from most others – like having those EYES! Look carefully and you may see the ‘trick’ that was used – which some might regard as perfectly legitimate, exploiting another fixed feature of ImageJ, albeit one that you can work around (CLUE!) and indeed was worked around. Answer – will be given in 24 hours.
