Riddle Posted on January 29, 2013 by Michael Willems Namely: What went wrong here? Hint: f/8, 200 ISO, at 1/400th second, lit by strobe flash.
Studio strobes don’t do high speed sync. The shutter is already closing. Try it again at 1/160th or 1/125th.
That’s right, Ron, spot on. Obviously I accidentally moved the shutter to a speed that exceeds the flash sync speed of 1/250th sec. So the curtain isn’t all the way open when the flash goes.
When using Pocketwizards you lose a few more ms, so you use 1/125th sec just in case. Which at f/5.6 and low ISO leads to ambient going away, as you see.
I have done that many times. So I know what went wrong. My learning curve of lighting.
I suppose there’s something to be said for electronic “shutters” that don’t have a sync speed limit. (I’m always a bit amazed how my 10-year-old Olympus can sync perfectly at 1/1000, while every modern SLR I’ve tried tops out at 1/250 or worse.)
I had that happen to me not too long ago. Luckly I clued in right away to what it was, having done it before by accident.
Also wanted to say I love your site Michael. A great resource, thanks for sharing all this great information.
Thanks for the kind comment, Jeremy!
