Hello all,
I am a (very) mature PhD student at Lancaster. I have joined here for two reasons; firstly my interest in photography has moved ever smaller in scale - from landscapes to small spaces to closeups, and on down to now macro; and secondly my current research project has me needing to try to create 3D models of very small rock particles - 1mm and less - the hope being I can do it from macro images. I am hoping I can find my way in here :-)

Hi Chris,
I am looking at volcanic ash. I want to look at the structure of many particles, and although I could use the CT scanner or SEM, those methods are very expensive. If I can work out a photographic method then I may have a useful cheap alternative.
they are light grey to dark grey and very opaque.

You can try with light microscopes or microscope objectives in a macro setup, but for your goal (If I understand it well) SEM is the way to go. Volcaninc ash particles can be really small, 1mm are often qualified as volcanic sand more than ash.
I would suggest you to first try looking your samples under a normal optical microscope and at a reflected light microscope if available and compare it with SEM.
