Played around with my studio strobe without any modifier, directly at my feet (camera right) at 1/8 power, and f=7.1 to get a bit depth. And after the black & white conversion, I also played around with colours and curves a bit. Not there yet, just trying:
Olympus E-520 with the 50 Macro lens, triggered by IR remote. Flash triggered by radio remote (Yongnuo CTR-301P).
Thanks for viewing.
