I quit photography for a bit due to some IRL issues (switched careers, mental health, etc. etc.). Decided to pick it back up recently, but forgot a lot of the stuff I knew. This video was the easiest refresher on one of those photography tricks I was really really into!
Always happy to help!

What are some creative ways YOU can use rear curtain sync??
Thank you
You're welcome
realy thanks
Glad to help!
I like it.
Thank you Greg!
Nice video, thank-you for that. I had a question about the "pre-flash to show the exposure". I don't understand the purpose of that. Did the pre-flash go off before the shutter was opened? In that case, I don't see how it affects the final image. Is it trying to meter or focus or something? That wouldn't make sense since everything is in manual right?
Hey Speedracer77, sorry if I wasn't clear about the pre-flash.
The Pre-Flash goes off, letting you know that your shutter is now open and taking in light. It happens in an instant before the shutter opens and has no effect on the image.
Oh I see, thank-you for the reply and explanation.
No problem, glad to help!
Like the shirt!!!
Thank you!!
Hi @Run N Gun, i just wanna ask how do you do rear curtain sync during slave mode, i use my built in cam flash to trigger my external flash
Hi Anthony, depending on what camera you're shooting with and the external flash that you're using- You should be able to switch to rear-curtain-sync, and your remote/slave flash units should follow suit and fire before shutter closes.
Give it a try and let me know!
Off-topic question - what brand is your clocks in the background?
I honestly don’t remember. They stopped working and I threw them away when I moved. They weren’t great quality and wouldn’t recommend them.
Thanks for the video. I have tried this technique with a Sony a7r and find that even with rear curtain sync, I get a small amount of "front-trail" as well as the rear trail. (The faster the object is moving, the longer rear and front trails.) Any idea why this is happening? It makes sense to me that there's a very short amount of time between when the flash fires and the shutter closes and that could account for it, but none of the demonstrations I've seen online mentions or shows the effect. Thanks!
Hey, Michael! You you sure it’s in rear-sync and not another flash mode? It does sound like your flash is popping mid-exposure.....
@@RunNGunPhoto Thanks for the speedy reply! Yep, the camera is definitely set to rear sync and the rear trails are much longer than the front trails. I tried it with a Sony a7rII as well and got the same result. I wouldn't be surprised if it's a Sony-specific thing. I really appreciate your input. All the best
That is super strange! And there’s no forward movement? With Mirrorless, I can’t problem solve and say Set the shutter to a couple of seconds and see when the flash pops vs when the shutter opens and closes... since there is no mirror. Is the alpha e-shutter or mechanical?
@@RunNGunPhoto The shutter is mechanical, so in that regard it is no different than a DSLR. Not sure I understand your question about forward movement. The subject is moving, and we can call that movement "forward". There is, as expected with rear sync, a trail behind the subject. But there is a much shorter trail in front as well -- maybe 5 - 10% as long as the rear trail. I have verified visually with exposures of a few seconds that the flash is definitely triggering ~ at the time the shutter closes. I'm pretty sure what's going on is that there is a non-zero amount of time between the flash and the shutter closing. I'd be *really* interested to know if you can get the same result. One way to find out would be to shoot something that's moving fast, like shooting the dart in your video instead of aiming the camera at yourself, with say a 1/8 or 1/4 sec exposure and strong continuous lighting so the trail is strongly visible. Please let me know if you try it. Again, many thanks for engaging with my question.
Sorry for the confusion, but yes, I mean movement (presumably backwards) that would create the trail.
eg. If you're holding still, waiting for the flash and move forward a bit at the end.
I've used this technique, hundreds of times with my Nikons and Canons and I've never seen anything like what you're describing.
It's possible that it's a Sony thing. Have you tried googling to see if anyone else has had similar issues?
Why does rear curting setting always fires two flashes? One at the start and the final one right before the 2nd curtin closes? Doesnt that kill the purpose of freeze at the end??
There are a couple reasons for "pre-flash," which is what you're seeing. In this case, as I explained n the video, that was to reduce the effect of "red-eye" in portraits. Sometimes cameras also use a pre-flash to meter the scene before the shutter opens.
@@RunNGunPhoto I know... Question is, why it doesnt happen in 1st curtain setting?
for some reason its not working for me...Canon T6s ISO 100 F 11 shutter speed 1/6 or longer. My flash is ETTR and I put it on the Rear curtain setting... I am simply not getting that trail of colour even though i'm shooting in low light. what is happening?
If it’s to dark, you’re not getting enough ambient light to make a trail.
How dark pr bright should it be?
You'll have to experiment. It depends on your exposure settings. If your camera can't see your subject before the flash, there won't be a trail leading up to it.
is this possible with off camera flash ?
Yes it is!
@@RunNGunPhoto thx for the reply mate tho i think ill have the rong remote for it lol Hâhnel combi TF
@@GoaPrince That possible - All of your flash sync setting should be controlled in-camera though.
Cool
Thanks for watching!
So in other words, instead of freezing the start of the action with front curtain, rear curtain freezes the end of the action. Thank you. Sorry about England. I wanted them to win!
That’s correct Vasilios! And I actually enjoy watching the women’s cup more then the men’s. The match is always more intense and so much more interesting.
Could you please tell your settings as well
Your settings will be dependent on your environment.
You need less ambient light.
Arne, the ambient light is what gives the image the motion trail. That's the intended effect when using rear-curtain sync, and kinda the purpose of this video.
@@RunNGunPhoto Instead of ambient light he could use another flash. Less blurry.
@@rewind9536 The blur was intentional to show how Rear-Curtain Sync works. Yes, another strobe would've frozen the motion, but also have defeated the entire purpose of this lesson and technique.
I may have mixed up front and rear curtain sync with your rear curtains sync using ambient light.
Ahhh that makes sense!
The state of that fake England shirt. Good video though
It was a gift. It was comfortable. 🤷🏼♂️
Sorry, not sorry.
