Onboard Flash
Some Nikon cameras, like the D7000, the D700, D200, D100, and
others have flash built-in. It is there if you want to use it. But
onboard flash is really not useful for macro photography because it
can't be moved anywhere but where it is. It is too direct and in your
face. One thing you can do is find some kind of (or make a)
diffuser that will soften that light. That helps. Or you may be able to
build some baffles that reflects the light upward, outward, or
sidewise to good effect. I have a bunch of Nikon flashes, but don't
them.
