I'm not shooting at f25. I know what DOF is, you still don't. LOL.. All photos above f 20 uploaded in that your Facebook group are garbage.

Still waiting for those awesome blackwater photos of yours. It's kind of hilarious how to waltz in and, despite having zero practical experience of your own, declare that all the experts in the field are Doing It Wrong.

You are talking in vain. If you call those awful things photos and persist, you will take photos like the ones you took all your life.

LoL. This is bad quality.. You do not understand. I showed you the f8 and f22 photos taken at the same time. Do you have a comparison photo taken F8 and above f20 that will make it easier for you to understand? Never in your life you have taken a photo like this and compared it.

You've shown a photo with a missed focus, and compared it to one where it was mostly on target, but part of the subject was blurred away due to insufficient depth of field. Bzzzt, try again.

There is no missed focus there. Ministers, those who understand see.

If you don't understand you can not understand. This is your problem.

You put a bad photo here because it's good, the viewers see it.. This is your capacity.

You could shoot at a speed higher than 1/160 with your HSS supported TTL converter and Retra flashes. Why did not you do it?

Because, you complete ignoramus, it is not supported.

You are ignorant.. you delete what you wrote.. most of what you wrote is wrong.. those who read it see.

No, you don't know. You didn't use it, you didn't experience it. With enough capacitors and batteries, all flashes are triggered in HSS. There is no need to write HSS on it.

It is obvious that you have zero understanding of how flash sync functions, and what HSS is. Go read some articles on the subject and come back.

You know nothing. There's no arguing with an ignorant person like you.

Even the Nikonos SB 105 fires 1/2000 in HSS. It is not at minimum power, it is effective in all macro shots up to 3 meters.

Do you even know what macro photography is?

It's a shame, you're talking nonsense. The flash power, which affects 3 meters, is more than sufficient for macro shots of 10 cm - 20 cm - 30 cm. If you don't understand that, it's your problem.

The YS 250 Pro does 10fps at half power. I just spoke with the Sea&Sea distributor and he confirmed what I said. I just shot a video for you, watch it.

My camera takes 5 frames per second. The YS250 pro fires nonstop at half power.

No, it tries to fire, at whatever capacitor level it has at the time it receives the triggering signal. Go back and look at your exposures and you'll find significant differences between the first 1-3 shots and everything after that. Simple physics - YS-250Pro is rated for 200 full-power flashes, so let's be generous and give it 400 half-power flashes. At 10fps, firing continuously, it will reach that number, exhausting the battery within 40 seconds. There is not a chemical battery in all of Christendom that can go from full to empty in 40 seconds.

You know wrong. Go ask your Sea&Sea distributor. Those who read here should look at the video.

In addition, similarly powerful Ikelite DS 230, Supe D Max ..etc.. flashes can fire up to 15 fps.

I don't know about DS230, but SUPE D-MAX is noticeably less powerful that Retra Pro, see the review here: https://wetpixel.com/articles/strobe-review-scubalamp-d-max-and-retra-pro-flash/P3 - the manufacturer's claims of 250 W/s are baseless; it's likely around 100-120 W/s.

You see that everything you wrote before is wrong. Don't read the forums where ignorant people write, go check the specs of the flashes. No manufacturer writes in their specs something that they cannot do.

You don't have enough knowledge and you're tiring me. I took it for you an hour ago. Triggered TTL and HSS on 580EX II with fiber optic cable to YS250Pro. I took it wide-angle so you can see the sync too. 1/200, 1/500, 1/1000, and 1/2000.

P.S: Currently there is a problem with DP, it does not add photos. I uploaded it to my gallery. I'll add it when the problem is fixed.

OK, look from here;

1/200 https://flic.kr/p/2n12eqA

1/500 https://flic.kr/p/2n12erh

1/1000 https://flic.kr/p/2n18Qig

1/2000 https://flic.kr/p/2n17aQU

What you're witnessing here is a combination of HSS working on your 580EX II (which lights up the room overall), overexposure produced by shooting directly into a flash, and the atypically long pulse duration exhibited by YS-250Pro (which keeps glowing during the length of your exposure, and since it's so bright, it clips the highlights despite the drop-off in intensity); see reference here: https://wetpixel.com/forums/index.php?/topic/60459-flash-duration/&tab=comments#comment-386683

You used to say that HSS won't do it, now you're rolling it. There it is.. and is doing it.. You have a lot to learn.

Do not talk nonsense.. Even 3 meters is enough for macro shooting, even more.

What the hell kind of lens are you using for macro at 3 meters, an 800mm telephoto? Macro photography is generally characterized by subject reproduction ratios of 1:2 to 1:1, with greater than 1:1 magnification falling under the umbrella of supermacro.

You talk like a child.. You still don't understand. You wrote that flash gives too little light to be used.. I wrote no, it works up to 3 meters even in 1/2000.. I wrote above what you don't understand.

I did it wrong... I'm dealing with the ignorant. I wrote it here only for those who read.. Those who read and look at the photos will see what's what.
