By the way Danny have you tried to photo a bullet coming towards the camera and stop it with flash, and if you do try where do we sent the flowers too?
I actually tired that Dave, now I can only see out of the left eye
yeah, that one
No wonder I can't focus properly any more, I'm cock eyed.
I actually tried 2ms, 5,ms,10ms,15ms an 20ms. So somewhere in between there, would be the bullet. If you could spend the time and tried a few dozen eggs, you would get it for sure
Jan wouldn't give me any more eggs
Home made unit that one. My brothers an electronics technician.
That egg shot there and going through my notes was actually at 1/64,000th of a sec. Not 1/32,000th. Yes as we set the shorter durations, the distance must decrease. Fast duration = less power and thats where Stephen Dalton comes into it. Very clever guy and I'm glad you have that book. Its one I must get. Time to check out Amazon.
Even though the flash duration is a lot faster than the shutter when set to std sync, the problem comes in when the auto sync kicks in. That now tries to control the flash duration and we then have no control over that high speed. Also which can be a benefit, is cameras that can switch to rear curtain sync. The advantage with that if we have it, is that it can show a trail behind the subject in motion. Certain subjects only though. With the mechanical complications of shutters/curtains, we are far better off to be in complete control of the flash duration. Like most photography IMO, the camera is just a dumb box.
All the best and interesting subject.
Danny.
Worry about the image that comes out of the box, rather than the box itself.
