Very interesting stuff. It would be a huge assistance to all of us T'Netter 'What Is It' researchers if you photograph your finds against a darker background, preferably in natural light and especially in focus.
By simply using a darkish blue cloth as a background, natural light
(or a couple of light sources from different angles - for example - a table lamp and a hand held torch)
For focus, nothing beats a tripod (I paid NZ$15 for mine - so about $8 USD)
If you want any more assistance, just PM me.
I intend sending this message to everyone who posts a What Is It pic with a white/light/kaleidoscope type background.
We'll get it right eventually.
Yeah, Right! - is a famous NZ saying.
