I thought I'd try a little experiment with photographing miniatures, using a small focusable LED torch hand-held to get a spotlight effect. The torch was very cheap; it only cost me a couple of bucks, and it runs on a single AA battery.
I used quite a small aperture (f22) to get a decent depth of field, which meant a very long exposure. Being hand-held, the light wavered about quite a bit, but that was probably a good thing as it softened the edges of the shadows cast behind the mini a bit.
I'm not unhappy with the result. It's crude, but as a proof-of-concept I think it shows promise. A second torch, further away, could be used to add a bit of fill light too, I guess.
I note that this ettin has got a bit dusty. He could do with a wash.
