- In this episode, Mark Wallace dives into the fascinating world of sync speed and external flash. Discover how sync speed sets the limit on your shutter speed when using a flash-unless you're harnessing the power of high-speed sync. Curious about the difference and how it all works? Dive into this video to uncover all the answers!

I already understood sync speed prior to this video. However this was the best animation to demontrate sync speed I have ever seen. Well very done. As I wrote before: you are a very good edjucator.
Thanks!
Hey Mark, Thank you. This was the most clearly explained video with examples on Sync Speed & HSS that I’ve ever seen.
Glad it was helpful!
Very well explained. You cleared it right up for me and that's hard to do. Thank you for sharing.
Glad it was helpful!
Best animation to explain this concept. Great job.
Wow, thanks!
very informative. Just got understand how the High speed functions.
Great to hear!
Thank you for this explanation of how it works, simply explained for my simple mind
You're very welcome!
Best video about sync speed 👏
Awesome animation.
Thanks!
Great video Mark!
Thanks, Humberto! We need to meet for tacos soon. 🌮
@@MarkWallaceVideos were waiting for you
I finally got it) Thanks a lot for such a clear explanation!
You are welcome!
Thank you
Glad to help
Excellent thank you.
Always impressed
W your training!!
Thanks, glad it helps!
Very helpful thank you
You're welcome!
Thanks Mark
Very welcome
I now understand HSS! Thanks!
Thanks! Now you can explain why CATIA is still used by so many industries when SOLIDWORKS clearly has a better user interface. Also, can you please explain how to use the Positioned Sketch function to align the Origin and Orientation of H and V direction to the features being created? I never get that straight.
@@MarkWallaceVideos Sure! SolidWorks, while being a great machining modeling software, lacks much of the surfacing tools necessary in many aerospace and ship design applications. The complex contours in aircraft and ships (surface and submarine) require sophisticated surface "lofts" to define their OML (Outer Mold Line). CATIA excels at that.
The Positioned sketch (preferred by experienced users) is a simple pull-down option in V5 whereas tends to be the default in V6 (depending on how your IT department has set up your standards). To define the origin of the H and V directions, you'll need to define your sketch plane and then define the desired direction using wireframe geometry, typically a line on the sketch plane or a plane that is at a defined angle to the sketch plane. It really depends on what the user needs. Many times the origin of the H and V is irrelevant but makes it possible to swap the orientation of the sketch if one desires it to be mirrored without actually needing to do any geometry changes. Again, it depends on the need and how the sketch is set up but using Positioned Sketch offers more flexibility on sketch orientation.
Great video!
Thanks!
New Videos about
- Histogramm
- whitebalance
- Colorchecker etc.
would be nice!
Thank you!
You're welcome!
Thanks, Mark. Now a days some cameras have only an electronic shutter (my Nikon z8) and others have what they call a "global" shutter. It would be nice to understand what is different - if any - when you use flash with those cameras. Also, I seem to remember having seen that "silent" shooting can prevent the flash from firing, but I don't know why that is. Thank you!
This sounds like an excellent idea for a future video!
There's an alternative to High Speed Sync called "HyperSync". This relies on the flash duration of the speedlight/strobe relative to the slit shutter. It works better with a relatively slow speedlight/strobe (that has a longer flash duration than a fast one).
And as we want to shoot at high shutter speeds, we need to have sync moment that coincides with the departure of the first curtain. This would be called "FP" sync, rather than "X" (see my other comment).
So with a camera with a slit shutter or an electronic shutter that effectively boils down to a slit shutter, we need to distinguish 3 sync moments:
X-sync - pops the flash when the first curtain arrives at the other side and the second curtain still has to close.
"2nd curtain" - a variant of X-sync where the flash pops when the second curtain starts to close.
FP-sync - pops the flash when the first curtain starts to open.
My flash trigger has a feature to measure flash duration and get a histogram of light as function of time that also indicates the sync moment. And with that I can shift the sync moment in the trigger (The Raven).
The advantage of HyperSync is absence of banding that HSS could cause.
What if your speedlight or strobe is too fast for HyperSync?
Well, imagine you shoot outdoors sports shots in the dark. Whatever flash you use, the top of the image is dark because the sky is too far away from the flash.
The foreground is overexposed.
Now with HyperSync you have less overexposed foreground ;)
I worked with a few companies over a decade ago to help develop hypersync. In my testing and use the results of hypersync are inconsistent at best. A few photographers use it very successfully, but I steer clear of it. :)
@@MarkWallaceVideos - appreciated. It requires some consideration. My Nikon speedlight with 1/880 sec full power is less ideal than a cheap Chinese God Ox flash that sends full power out in 1/200 sec. Between broncolor and Profoto, the latter generally is slower and may do better.
But then reducing flash power will cut these times shorter. Potentially at 1/2 power the flash duration of 1/200 at full power becomes 1/400 sec.
When you get it to work, overpowering the sun should be easier than the stroboscopic flash pulses in HSS from one full capacitor charge.
So the moral of the HyperSync story is "stay at full power" and know your flash durations and test these concepts.
With PocketWizard (FlexTT5) triggers I could shift the HyperSync moment between camera and flashes. With the Raven I have a measurement of the timing on top (Raven supports several flash trigger/receiver systems and can control two different once at a time).
Basically, a slit shutter with 1/200 X sync takes about 1/200 sec for all faster exposures (it may be just a bit faster). So only full coverage of that total time is needed for HyperSync to work, provided we get the FP sync moment right.
I know all this, but I'm still going to watch it. I just like people's take on stuff.
Good to know, Martin.
@@MarkWallaceVideos You did great with this. I was going to say do one on rear curtain, using the old school car tail light setup as a demo, then I found a guy that looks a lot like you with dark hair, talking rear sync.
Great video. Can you explain how the sync speed works with a Hassleblad X2D? Being new to photography, I'm purchasing this camera in a few months for my degree program starting in January, but I've read that the Hassleblads sync speed is faster?? Can you explain the difference?
Yes, absolutely. The Hassleblad has a different type of shutter. Most cameras have a "focal plane" shutter with the two curtains. The X2D has a "leaf shutter" made up of a series of blades and it's in the lens, not the camera (one of the many reasons the lenses are so expensive). The leaf shutter works differently, there's no second curtain to block the light, so it can sync at all shutter speeds. Google "Hassleblad leaf shutter" and I'm sure you'll find some images to see how it looks and works.
@@MarkWallaceVideos Thanks, as a new photographer, this was kind of confusing.
