Default Slow shutter speed sync

Dear members,

Here a picture of a facebook friend (who gave me permission to post in this forum).

https://www.facebook.com/photo.php?f...type=3&theater


Here are the parameters : Old Olympus FL-50R flash in a 20x30softbox, probably about 6ft from the subject. Triggered by Pocket Wizard transciever.

What I find very intesting is the shutter speed : 1/40th second ans .

Could someone explain how this portrait is so tack sharp without ghost with such a low SS !

Highlights in the model were illuminated by the flash, This would make her appear sharp. A few wisps of hair do show motion blur. Under the circumstances 1/40 second isn't really low. That is about the shutter speed of the box cameras of generations ago, and faster than the speed used in many studio portrait cameras before electronic flash.

There's your answer BJ

also unless I missed it, you did not give a focal length....which would give us a clue as to whether shutter speed was normal, or a bit out of the norm.

Judging by the field of view and reported camera-to-subject distance, I would say this would be something like 50 to 85 mm FF equivalent.
