Good point. By 'here', I meant the Hog. Sorry for stepping on your toes.

Regardless of the truth of your assertion, people do it all the time.

Most folks don’t seem to mind, so I’m off my soapbox!

I was playing around with busting balloons. It wasn't easy. This one I added a face because The balloon looked like a hat .

Your initial advice was not incorrect. The duration of a flash is much shorter than a shutter duration. The problem with extreme high speed photography is reacting to the action you are striving to capture. By the time you see it in a DSLR viewfinder, you’ve missed it: the shutter is pressed (time elapses), the mirror goes up, time elapses, the shutter opens, time elapses. Result: missed action.

Don't know what advice you are referring to. Yes, the flash duration is very short and with the MIOPS, no lag, but the shutter does and the flash is all packed away and thinking about other things by the time the shutter actually moves.

The original famous photos of Doc Edgerton ( http://edgerton-digital-collections.org ) featured balloons bursting, but they were popped by a bullet, and the flash was triggered by the sound of the rifle firing. He had a rifle and bullet trap in his photo studio/lab. If you have a safe place to fire a pellet gun, you could use that. He built the strobes to fire when triggered by noise, and darkened the room and left the shutter open for the photo. Of course, this was 1940's cameras and his personally designed and constructed strobes.

Shooting in the dark using the Bulb setting is a good way to go. As for shutter lag, have you noticed it in other situations? That used to be a concern with inexpensive cameras years ago, but better, newer cameras seem to have no lag.

Doc Edgerton eventually founded a company called Rotron. It made "air movers," also known as fans to the rest of us, and the government was one of its biggest customers. We have a Rotron plant in our town, although it's now Ametek Rotron.

My Canon has shutter lag and in fact IIRC Canon publishes the shutter lag number for each model in their specifications. You press the shutter release and the mirror has to be moved out the way in normal use. That takes a bit of time. I believe with my camera is is about 36 milliseconds which is pretty fast. Some are slower.
I agree on trying bulb in darkness. Triggering the flash might be the trick. My Speedlite duration is roughly 1/1000 second at full power and 1/40,000 second at 1/128 power.

I'm amazed! All the gear; all the expenditure; all the talk!
For a photograph of a bursting balloon; already done thousands of times!
Like watching paint dry.

Man, you haven’t mentioned sync speed? Are you at sync speed?
Will your flash do High Speed Sync? HSS could possibly solve your problem.
Lag should be taken into acct by the sync speed, I think.
And you might want to experiment with First or Second curtain modes. Good luck

working in the dark sounds a solution, if you can find the pin to burst the balloon
