Huanjie..single strobe.. using Inon D2000.
Actually, this is the first time I am using a strobe... so its both a blessing and a pain.
You do have to learn how to position the strobe to prevent backscatter and also to learn how to not overexpose your target, especially with macro.
I got some tips from seasoned pro photogs there... so it was slightly easier. The rest is up to trial and error.
