Much better to view on black
a fifteen second exposure, f2.5 shot with Canon's 50mm macro. i could barely see to focus! actually, i couldn't. i focused on the one you see now with the lights on, then shut them off and took the shot. i took one more at a random focus plane and then my battery pack ran out.
the orange fill is streetlights through a window about 25 feet away (streetlights probably at least 100 feet away from flowers if not more). blue flowers lit by cell phone "strobe" light feature moved around during exposure. photoshop used to adjust exposure and specific color channels.
