Got a question. I just took a pic with 3"s with Aperture F11 with an external flash using handheld. Surprisingly, the pic turn out to be very sharp.
I did a test again with a serious handshake and amazingly the shot taken was again sharp.
My question is
1) Is the shutter opened for 3sec to absorb the light to balance the exposure?
If 1) holds truth, how do you guys explain the sharp pic with handshake/handheld ?
