Paw print?

[fred_dot_u]

The idea of a lithophane from the photograph is a sound one. It reduces a good number of uncertainties to nearly zero. Using a white or translucent filament and a high contrast photo will give you good results. Another aspect of a lithophane is the novelty of the invisible image appearing from the print. I suspect with the right lighting the lithophane might appear as the positive of the paw, rather than the depression of the cast.

The overall size is still a factor, although you may get sufficient detail from a lithophane if the settings are tight. In what dimensions are you working?

I have a couple ideas - one is to place a small print into a 30mm glass locket that allows for up to 4mm of material. Tight area to be sure - if that doesn't work out I can simply print out a circular disk of any reasonable size and include a small hole to place on a chain as one of a collection of charms.

Thanks for the feedback and ideas, I will start experimenting.
