It was micro seconds not nano. It is milli -> micro -> nano

The color shift at 13:01 is most likely due to the shutter speed being too high to capture the full flash. The power curve you discussed in your previous video is linked to the flash's light power output and the color temperature the flash produces. The first part of the flash curve tends to be cooler, and the end of the curve tends to be warmer. With strobes and most recent studio flashes, at lower power, you tend to get a more blueish light than with full power images because the flash curve is cut before you get the warmer part of it. The same goes when you switch the action or speed more of your flash on; the light tends to get cooler as the tale of the curve is being cut to optimize for short flash duration. In your case, it's most likely due to the flash being longer than the exposure; thus, you get the early part of the curve. Adjusting the flash timing on the camera, you may get a different part of the curve, thus a different temperature and power output. That's the issue with global shutter; there are so many variables that consistency shot to shot may be difficult to reach. Try and use your flash trigger with close to empty batteries, and you may notice more significant variations because the triggering is not as snappy as it should be 😵‍💫

Thank you for a DETAILED & COMPREHENSIVE demonstration of Global shutter and flashes. What an excellent job!

You could've used a fixed ND. VNDs are known for color casting and sharpness issues (2 glasses instead of 1).

Deceiving title ... I was not expecting this is part 2 of the global shutter video :o

Whenever you use a variable ND or CPL, you should set a custom white balance to get consistent results. Had you done that for the control group and the ND pics, the colors would have matched (but likely some softening of image due to filter). If you are a working professional that uses strobes all the time, the A9iii is worth it, despite the steep learning curve. But for mere mortals, it's sooooo much more practical to just use an ND with traditional sync speeds. Awesome job on this tutorial!!

Loved the video, thanks for the info!

Perfectly presented. I have no further questions lol. The thought at the end about using multiple flashes at different powers hadn't occurred to me. Global shutter is unmatched for single flash outdoors, but a possible headache with multiple flashes.

Another great video, super sharp

I wish I had thought to ask if you guys were still living in Puerto Rico when we came down last October to shoot some airbnbs in Luquillo

@11:30 If you had the mechanical shutter turned off and still got banding, you probably using the mechanical shutter with the electronic front curtain, yes?

Nice breakdown of the process to find the sync delays. It will hopefully be a solved problem by the time I’m upgrading to a global shutter body.

What would you say are the nain differences between the westcott system vs profoto ... my flashes are sometimes not that reliable but profoto is just crazy expensive

Great video. Always enjoy watching the content. My only thought is you did the HSS test with a speed light so of course it was going to tank comparatively. It's def way more usable with a more powerful strobe. Certainly not perfect but usable.

As insane as it is, I think the solution would be pick the same ridiculous shutter speed always and then bump the ISO to compensate. I feel like this would give you the benefit of: 1: always having the same offset to the flash 2: getting even more power out of your flash output 3: easily dialing up and down the overall scene as needed.

It would have been helpful if these part 1 and part 2 videos were more clearly titled as such.

Awesome video.

Yeah global shutter is kinda impressive, but for the price you can buy 10 Godox portable flashes (up to 600Ws power) and use A7IV :D. Also what brand is that ND filter that there is such color cast? $80 filters are giving almost zero cast. And also there are fixed ND filters which does not have any color cast. But they might be pain in the but if your exposure change or you switch F-stops :D.

What about latency issues when using a radio transmitter with off camera flash/strobes on the A9 III?

11:52 Is it RU-vid compression or is there severe banding on the left frame?

Internal inbuilt electronic variable nd filter would solve iso problem, but no major camera manufacturer does this. Profit rules them all me too

Does TTL work normally at faster shutter speeds?

Thanks for the video! Regarding the multiple flash setup, I believe there is an argument for owning/using multiple of the very same model flash, possibly at the same power setting and using the distance of the light to the subject to increase or decrease the amount of light on the subject. I‘m aware it’s not ideal and might not always be possible to get enough distance, but it’s my idea of a work around. Regards

An understated update on the A9III is the colors look great. I think the vivid profile on the A7IV looks good except oranges is really oversaturates. The A9III to my eye looks more like the vivid setting except I'm sure oranges are not wildly oversaturated. Probably the same color science as the A1 and A7RV, none of which I've had the chance to use yet.

the 1/500th of a second sync limitation is for using TTL. In manual mode it will sync at any speed up to 1.8. Wider than 1.8 the camera limits the fastest shutter speed to 1/16,000 (which creates a variety of problems for using some GM primes wide open in bright light because of the high base ISO).

Good information, I'd love to see you use a traditional pack with flash head or a monolight in the same setting. Over the pandemic, I played with a Profoto Compact with the Pocket Wizard Flex6 and was impressed using hyper sync.

Not sure what people expect with this tiny speedlight in HSS :)

I’m John with TSRC I was just curious if you had the chance to try our drone. I’d would be more happy to send you a free drone that you can test.

Respect for the efort

Given time, a standard will likely be devloped which automatically communicates strobe sync timing. Though, I'm sure we're years away from that.

Holy crap...at the two minute mark where you show all the setting needed just to get started...my eyes glazed over. I'm a Nikon shooter or I probably would have paid attention and took notes, but holy cow...if you have to do all that?? I'm impressed Patrick will all of your videos, and no doubt this one is great too, but I can't help but think that this has become MORE complex and not simpler (and that has nothing to do with your or your capability to explain complex subjects--which is extraordinary). Just for the record, i would watch you explain anything, any day, for things I want to learn. But how to use a Sony? nope, not now, not ever.

I would like to see what's happening if you use a trigger and do not flash on the hot shoe. Can everything still sync just right at 1/80000? Imagine in a real photo shoot you have to refer to your paper notes just to enter offset timings 😅 My first choice would be mkre powerful strobe or if I run out of power to put ND filter on. Also dinamic range penalty is to big on global shutter and price is insane 6k 😂 Better get 2x profoto heads and a7iv 😅

I have the a9III and 4 Sony HVL-F60RMII and love it

Great video.. I think you meant to say micro-seconds not nano seconds in a few places..

Can someone explain why ND with regular sync speed under performs in coparisson with regular sync speed global shutter? That does not make sense. Unless 1/8000th captures more light with global shutter from flash. But if regular sync is 1/250th and there is no rolling shutter how does it not exposses for all flash duration whe the whole sensor is expossed. Ant flash t0.1 is around 1/220th thats perfect because it is almost the same as a shutter.

Yeah constantly having to change the sync timing would drive me insane.

I can't imagine being on a shoot and faffing around with the nanosecond syncing with my flash and camera along with all my other exposure settings. Global shutter definitely maximizes flash output but the ND method is much more straight forward and WYSIWIG.

I think I just decided to be a natural light photographer

You forgot leaf shutter

I guess the first party flash is worth it after all, we won't need to fiddle with the numbers.

Off topic... I miss the covid series. :)

As a conclusion, shooting with ND filter outdoors is the best option.

This is a good video...but not as good as drilling holes in printer cartridges. ;)

The crazy thing about the Global Shutter power advantage is reframing it in terms of gear. If you can get a 3 stop advantage, what you used to carry big 600 strobes for can be duplicated by a 100 kit. Especially when you consider action shots where you had to be in HSS regardless and now you have an even bigger advantage. Consistency is an issue with having to dial in the adjustments. I'm sure in practice you'd just set it to something like 200 and just correct visually while accepting you aren't truly getting full power.

That's zero micro second not nano second

If that video thumbnail isn't screaming to have someone 'photoshop' something into it, I don't know what is!

As I said 3 Month ago, just forget all the 3rd party flashes for the time beeing. All these flashes are to dumb to understand the sophisticated flash protocol that SONY uses in there newer flashes. SONY also uses a dedicated processor in there flashes to handle the flash protocol. They work in TTL and Manual mode. I prefer the manual mode, as it allows you to adjust and match the flash power individually , when using them all together on your set. You even save some energy, as you don't need the first flash as in TTL. You can also display and change all the settings directly in camera, which is very convenient. You can go as low as 1/256 energy, 1/80000, F/1.8, ISO 250 and Hi+ and still have sufficient light. You can easily set different ratios between all the flashes. It works perfect. No fiddling. Just switch it on and start shooting. I shot more than 30'000 pictures in sports events and concerts in the past 3 month with the A9III, and about 1000 with flash in Hi+ mode on special occasions. Previously you needed a flash in the $10'000+ range. Forget this table thing. The flash manufacturers need to build smarter flashes, that can cope with GS. The conclusion is, that the current flashes are to dumb to cope with such advanced cameras as the A9III, using global shutters.

First comment

$6K??? Seriously???

nanoseconds ?

Patrick, you have always been the technical side of Fstoppers. Lee has zero patience to think this deep about flash and technical filters. Great content but can you Please let someone else find the thumbnails for the videos?....you had a contest while back about, "Cringe"..this thumbnail is one of that category. You are a solid good Dude, but Not a kissy face is needed, perhaps better your place is behind the camera? I didn't want click on this video because of the cringe factor. But, when you talk is all good. --sorry bro.. Some styling on your wild hair and proper lighting - you are Fstoppers, not MarketingStoppers I get it, but Dahang, a bit of a lift here is necessary. A bit of a consultation with an agency is necessary. You two cannot just post videos anymore without a guide. That is why your viewership and subscribes are down. Perhaps a new approach, a video like this both You and Lee review the subject, get his thoughts, then you divine to the details...followed up by, Hey Lee, does this change your perception? Would you take time to attend what Patrick points out, etc etc.... I dunno you guys have "it", but clearly are not doing it right.....

Sony, again... It makes me sick.
