Hi Mike, List,

Mike is right, the flash in macro photography is evil, sort of... (most
macro photographers use what's called a "ring flash" which mounts on the
end of an SLR camera lens)

It all depends on how you use your camera, if it's an SLR or a "Point &
Shoot". I don't flash at all, rather I like using a diffused full
spectrum light. $20 at your local Office Depot. Oh yeah and a plain
white piece of paper for the background. Simple. Everyone likes simple.

As for white balancing. Your camera's built in light meter reads
everything on average at 18% gray and white balances accordingly to how
bright or dark the subject/background/foreground is collectively. A
quick trick I use is to point the camera's focal point at the shadow
created by the meteorite while pressing the shutter button halfway,
thereby forcing the camera to use the gray to white balance. Wait for
the beep, this means it's focused, then while still holding the button
halfway I re-frame the meteorite in the center of the photo and fully
depress the shutter button.

Works every time... http://www.meteoritesusa.com/meteorite-photos/

Enjoy!
