I tried various methods of lighting for macro and you can read about these plus other contributions.
I eventually bought, or should say my wife bought the Canon twin light macro flash, this is the way to go, but is a little expensive, there are a number of photos in my gallery, most of them taken using the Canon macro flash.
This is a link to one of them.
