I just thought I'd share some samples of my Hypersync tests using Pixel King triggers and my battery strobe Jinbei Discovery 1200

After reading a few posts on this forum regarding hypersync, I decided to give it a test...My main driver was being able to use flash with wide F stops outdoors. I was Looking into Vari ND filters and single ND filters to achieive this look, until i stumbled on the posts explaing Hypersync with manual (studio) strobes.

the pixel king transmitter is placed in the Hotshoe as normal, the receiver is connected using the pc port to 3.5mm jack into the power pack.

upto 1/250th Shutter everything is working normal, I am able to get direct flash F11 at about 10ft from subject at 2/3 power about 500w/s :):)

So then you increase the shutter speed past Max sync and at the same time open up your F stop the compensate ( as you would do with an ND filter) as guess what, the same (actually slightly better) flash/ambient ratio and coverage...:) now this is all the way to 1/8000th shutter.:eek::eek:

as long as you compensate for each stop of shutter increase by opening the aperture the same stop, you get exactly the same exposure.

so 1/250th @ F11 is the same output as 1/4000th@ F2.8

example screen grabs below, SOOC.
if you look closely as said, you actually gain about 1/3 stop more efficiency out of your strobe......

I did try this at each power setting on the strobe pack, and got the same results at minimum power and Max power:)

I am blown away by this technique, thumbs up for Pixel Kings..!!!

Thanks, hbomb69.

I suspect that Pixel could well have used Jinbei strobes for testing and timing in the Kings.

I tried retiring, but gave it up - it's a dead end

Talk, yes; real-life photography not so much!

I have done over 1,000 test shots to determine which exposure techniques are usable in real life. I concluded that both the high-speed sync ("flat light") and pre-sync "hypersync" are usable with my 50D and the Kings, and use them regularly.

Looks good with just a bit of overexposure in the HHS image. But nothing too special and definably will be a powerful tool and better option then the PW TTL system.
