Hey, hey, hey...
Stop trying to compare my pix to Hirsch's. He really didn't have a very fair playing field. My flash pix were destined to be better balanced than his.
Why? Well, I was wearing my dampening weights, which control ambient vibrational harmonics, on my head. There is no sense in buying the expensive "photo-phile" ones, either. I make my own. Simply take a garden variety cinderblock ($2.00, home depot) and glue three "plumb-bob" style pointed brass cones ($3.50 ea, same source) in a 2" equilateral triangle pattern in the center of one side of the block.
Now, before attempting to shoot flash in mixed light conditions, simply place the block on the top of your head (with the sharpened - you must sharpen them each time for best contact with the skull - point resting on the top of your head) solidly supporting the 47-lb cinderblock.
You can easily hand-hold mixed-light flash photos down to about a quarter second.
Naturally, I was not able to take a photo of myself while so outfitted, but I am surprised Hirsch didn't include one with his set.
BTW, sorry about the blood drops on the Gilmore, Hirsch.
