Working with light: Part 1

Australian $2 coin, paper clip and bolt.
Working on reflecting some of the light back to reduce shadows.
Used a tin foil baking dish, may be better if I buy something that is meant for the purpose.

Australian $2 coin, just by changing the position of the light, 2 different effects.

Not really sure which looks the better of the two.

I am reasonably happy with these two photos of a bolt. I have minimized shadow.
