Slow Sync Flash

Slow Sync Flash

One camera function that can be a lot of fun to play with (and that can get you some interesting results) is slow sync flash.

Low Light Photography Options

When shooting with a subject in low light situations you generally have two options; either to shoot with a flash or to shoot with a slow shutter speed.

1. Flash – When shooting in low light with a flash in auto mode your camera will choose a relatively fast shutter speed. This means that your subject will be well lit and that if it is moving it will be frozen and as a result will be sharp. The problem with this is that it can also leave your subject lit up too brightly and can leave it’s background looking very dark as there is not enough time for the camera to collect any ambient light.

2. Slow Shutter Speed – The other option is to turn your flash off and shoot with a longer shutter speed in order to collect enough available light from the image to get a well exposed shot. This can be an effective technique if you’re shooting landscape or environmental shots where everything is nice and still – however if you’re shooting a moving subject it means you’ll get motion blur which could ruin your shot.

Both of the above options are legitimate technique but both have their weaknesses. Another options to consider is slow sync flash.

What is Slow Sync Flash?

Slow Sync Flash is a function found on many cameras that tells your camera to shoot with both a longer shutter speed as well as firing the flash. This means you get the best of both worlds above and can both get a relatively sharp shot of your main subject as well as get some ambient light from the background and foreground.

Some cameras allow you to access slow sync flash manually and set exposure length and flash strength but on many compact cameras there is a little less control given and it’s presented as an automatic shooting mode, often called ‘night mode’ or even ‘party mode’ where the camera selects the slower shutter speed and flash strength for you.

Rear and Front Curtain Sync

If your camera gives you some manual control when it comes to slow sync flash you might find yourself presented with two options called ‘rear curtain sync’ and ‘front curtain sync’.

These two modes sound a little technical but to put it most simply they are the way in which you choose when to fire your flash during the longer exposure.

Rear Curtain Sync – this tells your camera to fire the flash at the end of the exposure. ie when you press the shutter your lens opens up and starts collecting light and just before it closes the flash will fire to light up and freeze your main subject (see the card shot to the left for an example where you’ll see the card trail ending in a nice crisp shot of the card).

Front Curtain Sync – this tells your camera to fire the flash at the start of the exposure. ie when you press the shutter, the flash will fire immediately and the shutter will remain open afterwards capturing ambient light.

You might not think there’s much difference between these modes but when you’re photographing a moving subject it can have a real impact. You’ll find many action/sports photographers will use Rear Curtain Sync when shooting with a panning technique.

Tripod or Handheld?

When using either slow synch in either mode (or in the automatic ‘night mode’ you will want to consider whether or not to use a tripod. Traditionally when shooting with longer shutter speeds it is accepted that a tripod is essential in order to stop any camera movement. Even the steadiest of hands will not be able to stop a camera moving over even a 1 or 2 second exposure. So if you want to eliminate blur from your cameras movement definitely use a tripod (and consider a shutter release cable).

However in some circumstances hand holding your camera while using slow sync flash can lead to some wonderful effects. For example if you’re at a wedding or party and are out on the dance floor the results can be great at capturing the mood of a night with those you’re photographing largely frozen by the flash but the lights on the dance floor blurred from you moving your camera during the shot.

Of course hand held techniques won’t work with every situation so experiment with both methods at different shutter speeds and by using both rear and front curtain sync and find the best methods for your particular situation.

    Please tell this technique available I my Nikon d 5100 ...and thank u for helping

  • Frank May 10, 2012 11:40 pm

    A very nice moment to use this technique is focussing on a dj's decks and at the end of the exposure aiming at the dj himself, you can then see the record spinning around the dj!

  • KT Pierce May 7, 2012 01:53 am

    I'm so irritated right now because I can't find a single web site that will give the technical specifics on how to accomplish any of these. These are just simple explanations. I know there is so much more to it than this.. I'm just frustrated. Forgive my venting...

  • Jeanne Marie September 16, 2011 03:14 pm

    Darren, I was surprised to see your name on this post when I found it. Why is it whenever I Google for a little help for my blog, I end up finding YOU?! Anyway, I've had a terrible time with the photos for my blog, and had already played with the auto settings and made some -- but not complete -- progress eliminating the funky shadows. Reading this post encouraged me to try again, and I accidentally found the source of the annoying shadows in my photos. I had some wall hung task lighting on, trying to increase the light in the room. Those lights were just throwing awkward shadows. Turning them off, then using just the central ceiling fixture plus some of the different auto settings ("portraits," "kids and pets," and "indoor" worked particularly well) solved the shadow problem. I thought I might have to buy some expensive light diffuser. You've saved me money and aggravation. Can't thank you enough for all the help you've provided for my blog.

  • P.C.Chowdhury September 13, 2011 10:08 pm

    Are there any compact cameras offering the rear-curtain feature? Some websites say Canon S95 has it but it is rather expensive. say the recent PowerShot SX230 HS has it. An authoritative list would be a great help.

    Hi, some week ago I tried with my nikon d90 and his integrated flash to reproduce Johnny Blood's shot. It didn't work. I just saw transparent hand in my picture. Is there an easy test that I can do to try slow sync without an external flash ? Could my problem be preflash ? I don't think so. Thanks :)

    Nice post. Everybody explain on their own way and your idea is clear. How come everytime you come up with idea but write in simple words and Flickr example most of the time. :)

  • Yucel November 11, 2010 10:14 am

    Your sample shots are very cool by the way.

  • Kathleen November 4, 2010 12:37 pm

    Ahhhhhhh should teach people how to shoot in Manual mode, or with an SLR ( film, not digital ) if you want everyone to truely understand what your saying instead of asking you what the setting is on thier camera. the best way to use flash is to actually use it like a real photographer, not letting your camera make desions for you. This is coming from a student phtographer perpective ( graduate in spring ). You will learn way more using manual settings and calculating your GN on your hotshoe unit. Then, oh my god, you people will not have problems with your subjects being unexposed and ghost like, because you will have learned how to calculate flash output, your shutter speed and your distance, and this would not happen. If you want to learn more about flash, ditch your expensive DSLR's and get a much cheaper film camera and enjoy the sweet smell of developer :)

  • St Louis Wedding Photographer October 28, 2010 07:04 am

    I hadn't heard the term slow sync flash before, but we do this every time we go to a wedding reception. We shoot in fully manual mode, so we control our shutter speed with each shot. Basically, what you're really getting with this technique is 2 different exposures. One exposure is what you have your camera set at - ie a 30th of a second. The second exposure is the exposure of the flash itself, which is super fast.

  • Paco M August 3, 2010 12:05 am

    Thx for telling this information so easy !!!

  • Shubhra Chaturvedi June 1, 2010 05:38 am

    I have a Nikkon D-40 and it doesn't have front curtain sync and rare curtain sync options, but it does have manual flash mode where it says full power or 1/2 till 1/32. Now whatever that means how can I use slow sync techniques on my camera...

  • Texan Mama May 27, 2010 02:04 pm

    I'd like to ask a question about composing my shot.

    Before I ask, let me say that I'm pretty much a novice but trying my best to learn.

    What is the best way to shoot a photo with good results when using slow sync flash? What I mean is, should the subject be in high contrast to the background? Does it matter? If there is any light in the room, should it be behind the subject or to the side? How fast or slow should the subject be moving to get the best result? Any answers would be appreciated. Thanks.

  • R.Vijayendra Rao March 29, 2010 03:59 pm

    Very interesting! The illustration has given me a very good insight on Rear & Front curtain sync. Thanks a lot.

  • Rama March 22, 2010 11:09 pm

    "SLOW SYNC MODE" doesn´t exist in Canon, so in that modes that the camera set automatically the shutter speed, you wont be able to play with it. This modes are Av & P.
    You have 2 options: use Tv or M mode to set manually a slower shutter speed.

  • David Hardwick Photography March 6, 2010 05:21 am

    Very interesting viewing. These pictures have turned out great. I must give this a try.

    Any idea where to set slow sync flash on canon eos 50d or 580ex flash units.?
    I've been trying to get this to work for wedding reception candids in poorly lit venues indoors.
    Can't find it in this camera yet.

  • Darin House November 8, 2009 04:21 am

    Definatly my fave new way to do night shots

  • September 21, 2009 11:51 pm

    Gotta love this technique - it's awesome for weddings, too.

  • hannsze September 21, 2009 02:35 am


    anybody can explain whats the difference between slow, rear, and slow rear flash please?

    Senario: You know how those fancy pictures are taken in night clubs where the photographer shoots at a group of ppl and then swirl the camera around so that the picture comes out with the people still looking sharp with a twirl of background colorful lights across the picture?


  • Andrey September 14, 2009 09:30 am

    In the wedding night party - "M" ,1/4 , f 8-f12, flash, max 1 metr from obiekt.

  • Kumaresan Vibhakar August 25, 2009 05:48 pm

    Every thig is fine but the present days cameras, that came after F80 / F100. Pricisely the Di cameras don't have the threading on the shutter release button to screw on the shutter release chord that absolutely essentialy for the shakesless & Slow Speed shutter release.

    The slow shutter speed & full opening night shots, that is held for the quite a long duration exposures cannot be achieved with 100% effect.

    Those who have nervous problems, heavy breathing with heavy body structure will have some difficulty in releasing the shutter even though the camera is mounted on a solid heavy Tri Pod. As per your comments what is the use of using the Tri Pod for the essential requirements with quality, less than the 100% with the above said draw backs. Thank U. Have a Nice day

  • Bob Kajang August 16, 2009 09:45 am

    I love slow flash its make my picture look so clear and didnt look so flashy and very minimize shadows...Another can use slow flash for people just set to high ISO setting ...this only recommended for low noise HI ISO camera like newest DSLR

  • vije July 10, 2009 01:35 pm

    Thank's for the info..more i know ..more i don't know......

  • ROBERT June 1, 2009 07:37 am

    To Darren

    Thanks for the good job of explaining slow and rear synch. Earlier today I became frustrated when reading someone else's article on these. So I went back to the computer and searched more. I came up with your article and decided to give it a go. With your article I grasped the message you were conveying to the reader the very first time through the article. So you have done a very good job simplifying and explaining this.

    I have the D300 and I familiarized myself with it over the last year now. It has not been easy. With such a complex camera I think the best strategy is to "find yourself" inside the camera and then stick with this set of personal "default" settings most of the time. But even then one needs to understand and practice certain highly valuable techniques that are not used all the time and will require changing settings, and then changing back to the personal defaults. Slow and rear sych are perfect examples. I need to become proficient with these. You have given me a basic beginning understanding. Now it is going to take practice. One beauty of digital is that unlike film, it costs nothing to practice. With this D300 once I find the correct exposure settings I can choose to let the camera take over automatically (and I do choose that), i.e. I have no intentions of going manual. Been there done that. Thanks again and happy shooting!

    Evan, I must apologize for the silly "did" mistake, as I usually don't commit such language crimes. But I keep the "investment", since my time is very precious, and every minute I spend at the computer doing something that is not related to my work at all HAS to be an investment.

  • Flores January 7, 2009 02:16 pm

    Thanks for the tips. I have this problem for so long, especially during Christmas when I wanted to take pictures of my friends in front of the Christmas light. Without flash, it would be a total darkness of the persons and using flash simply destroy all the beautiful background.

    In my case, since mine is canon S5 IS, it is called 1st and 2nd curtain sync.

  • Emre December 16, 2008 07:53 am

    Hi Al,

    Thank you very much for the answer.Yet I don't get why it needs to figure out the light.Please correct me if I am wrong but if the camera is already adjusted to "freeze" only the last frame then that's not really needed to check the current light and fire the flash in the begining. Unfortunately my camera is not with me at the moment so I cannot check. Did you have any chance to experience it by yourself? I wonder if other models have the same features.



  • al December 15, 2008 07:54 pm

    Hi Emre,
    Someone told me that the flash at the start is just for it to figure out the light, and it is actually working as a rear-curtain thingummyjig.

  • Emre December 14, 2008 11:26 pm


    Does anyone happen to know the answer of Alastair's question? I also have set the rear-sync on my Canon 400D,and the flash fires at the beginning as well as the end. I dont get what's the point of having two flash fires???

    Thank you in advance,


  • Carter December 13, 2008 08:03 am

    Hey guys,

    Ive been trying this in a variety of different lighting situations with a lot of different ISO's, shutter speeds, and apertures and can't get anything to turn out quite right. Any suggestions?

  • Alan T September 17, 2008 05:08 am

    @ Patrick:

    I agree with you mate - there are so many people asking the same question about how to do this on their particular model of camera. If you don't know, then read your manual or google it before you post on here - that's just being really lazy and it gets really boring when someone new (like me) goes to read all the comments.

    I have a 450D and now I'm off to read my manual to see how this works!

  • Al September 15, 2008 07:22 am

    I have set the rear-sync on my Canon 400D, but the flash fires at the beginning as well as the end…. Can anyone help? The manual says that this will happen, but this seems to suggest to me that the rear-sync function is useless on the 400D....?
    Thank you!

    My point-and-shoot has the front/back curtain option and i never knew what it is. unfortunately my brother just broke the screen so i can't see what settings I'm on, or else I'd try this out. Only a week until my new Digital SLR arrives though, so this will be one of the first things I experement with!!

    You need to set your camera to rear curtain sync, set a shutter speed slow enough to record a bit of action and click away, everything you need to know is on this page!

  • alex mcroberts June 11, 2007 11:13 pm

    Yuva. Get a mobile (cell) phone with an LED light "flash". Go on to manual settings. Set iso to your second highest number. Set the exposure time to something like 5 seconds, and I usually use f8.0 too. put the camera on a tripod. Set the self-timer to 5 seconds. Setup your phone to put the LED light on. Click the button. Draw the shape. The Longer the exposure times the more complex the photo you can get. Use more than one phone to draw big things - like the "Revolution" photo - it took three phones at 15 second exposure.

  • Yuva June 11, 2007 05:49 pm

    Really Cool snaps alex mcroberts cud you share how you took those . Really amazing... Can anyone tell me how to do this in Canon IXUS 800 IS

  • Evan June 1, 2007 08:51 am

    louis- You cant really fix that in photoshop as far as i know. It happened because when you use a slow shutter speed and the subject moves too much or moves out of the frame it gets faed since it was such little time that the subject was in the position. To fix it:

    take the pic again, try using a different aperature setting to make your friend stand out more, and use a faster shutter speed. I use around 4-8(hundredths) for this kind of thing, you may want to bring it to 10 depending on the speed of the subject (in this case, the skater).

    but a good rule is if its really fast, make the shutter speed 3-5 stops slower than you "should." otherwise do 4-8 or so. and to keep the background from distracting from the subject, play around w/ the aperature to control whats in focus and whats not.

    Another cool thing you can do that might have been mentioned here earlier is to turn off the flash, put shutter speed to 4-8, and move the camera around while exposing. Try rotating, steaking across, up, down, anything. my personal favorite thing to do is zoom in while exposing. gives it a great motion. its awesome.

  • louis June 1, 2007 07:44 am

    Hey!! i tried it with a friend that was skating, front curtain sync, unfortunately in the shot the background looks awesome but mi friend looks like a ghost. Does anyone know a way i can correct this in photoshop? Should i make it in rear curtain sync??

  • Evan June 1, 2007 07:36 am

    two more things.....
    1. what is RAW? is it really low quality or really high?
    2. what is mirror lockup, and what else did they take out of the original Rebel?
    3. can you get firmware that supports 2nd curtain flash?

    ok i guess thats 3.....


  • Evan June 1, 2007 07:33 am

    why do i have to be "brave" to install that? Is it dangerous or something? Viruses? Crashing the camera? Erasing data?

  • Dave New May 31, 2007 12:22 pm

    The original Digital Rebel didn't support 2nd curtain sync, unless you used a flash that allowed you to set it on the flash itself. The 500EX for instance, will work, but unless you want/need a high-end bounce flash, it's a pricey solution.

    Canon purposefully crippled the original Rebel firmware, to keep it from gutting the sales of their 10D, etc. If you check around, you will find hacked versions of the firmware for your camera that (if you are brave enough) you can install that will restore most of the removed menu settings (like mirror lockup, etc). One of the most aggravating 'features' was the way it coupled certain shooting modes together. For instance, the JPEG 'sports' mode is the only one that uses the predictive focus system, but it forces you to shoot in JPEG, and disables the flash (like I'd never take sports shots with flash?). The Rebel firmware is essentially identical to the 10D, with a bunch of the menus NOP'ed out of the code.

    I gave up on the original Rebel as hopelessly crippled, and upgraded to a 20D. Much more flexible, for someone that cares about such things as mirror lockup, 2nd curtain sync, and being able to choose which focussing mode to use with which exposure mode, and to always be able to shoot RAW, no matter what.

    And for all the folks with Canon EOS bodies (whether film or digital) there is a great FAQ that will help you understand how to get the most out of your flash system at:

  • Evan May 29, 2007 09:40 am

    hey I cant find this on my Canon Digital Rebel.

  • Travel Photographer May 26, 2007 01:35 am

    Slow speed sync is a cool technique. It certainly opens up a lot of creativity in people.

  • Motorcycle Guy May 13, 2007 08:39 am

    I'm not even sure my camera has slow sync flash. I don't think its called that exactly but I'll have to check it out.

    Anyone knows if where can I set the 'Rear Curtain/Front Curtain Sync' on my Canon 10D?

  • Rog Patterson May 12, 2007 02:45 am

    Have a photo of my #4 son's Formula Vee race car trailing a long, red blur with the front half of the vehicle sharp and wondered how it was taken...thanks for the answer. My Olympus C740UZ offers 2nd curtain flash, so now I've just gotta find me a red race car.

    I have the Panasonic DMC-FZ50 - and reading the manual it suggests that the flash fires first ie front curtain, I would presume that the DMC-FZ5 would be similar - hope this will help Ziv......

    A smashing article......

    you people must not hear this enough, but RTFM! it's all in there. I'm surprised that a lot of you don't even have a basic understanding of your camera, enough to figure out where a simple menu item might be. when in doubt, rtfm first, then ask questions

  • Becca May 9, 2007 07:54 am

    Thanks mark!

  • anders May 8, 2007 01:06 pm

    never mind previous comment got it working

  • max May 8, 2007 12:25 pm

    what buttons do i press to switch between rear/front curtain sync?

  • anders May 8, 2007 12:11 pm

    It doesn't seem to work for me, I only have a 1 and 1.6 second exposure choices, is that to short to pull this off.

    So that's what Slow Sync Flash means on my Canon SD600. I'll have to try that more often - thanks!

  • Free Nature Photography Wallpaper May 8, 2007 01:31 am

    Not bad, I do some long exposure as well, check it out. I prefer modeling photography though...

  • Ziv May 7, 2007 11:38 pm

    does anyone knows if on the Panasonic DMC-FZ5 you can set the slow sync flash to fire at the end of the exposure? I checked the manual but it didn't say a lot about about slow sync flash and I checked their website but couldn't find the camera.

  • alex mcroberts May 7, 2007 11:06 pm

    Check out my link:

    that was using a slow shutter speed, and a couple of mobile (cell) phones that have a LED "flash". stick on the LED, use a tripod, go "painting"...oh and the longer the exposure the longer you have to draw :)

  • Jack Pearce May 7, 2007 08:35 pm

    Great tip thanks for that, explained it alot better than most the magazines out there.


  • Mark May 7, 2007 08:17 pm

    Becca rear curtain sync with a Canon 30D is set in custom function 15

  • Dave May 7, 2007 05:47 pm

    This technique is great in really dark clubs where it won't get overexposed. I'll shoot F4, ISO 100, 1 second, front curtain, and then move the camera around after the flash fires.

    You can paint streaks out of the lights.. here I made hearts out of all the candles on the tables.

  • Austyn May 7, 2007 04:31 pm

    I was curious if any one could tell me the settings for this on either a Kodak Dx7590 or Kodak C743, I have tried messing with the 7590 in manual mode to no avail any ideas?

  • Jakob Montrasio May 7, 2007 04:07 pm

    Thanks for the tip, I'll try that out with my Nikon D50 tonight!

  • John May 7, 2007 04:03 pm

    I did this shot with a long open shutter and a flash at the end in a dark room.

  • Paul May 7, 2007 07:04 am

    Superb shots - many thanks for that.

  • Becca May 3, 2007 10:08 am

    How do i get the rear curtain sync with a Canon 30D?

  • Eric March 25, 2007 04:04 am

    I have a sony A100, and I cant figure out how to get it to flash after the shutter opens. Any suggestions?

  • Kevin March 3, 2007 11:53 pm

    Press and hold the flash pop-up button, then rotate the thumbwheel. Try having the camera in the "M", "A" "S" and "P" modes to see the different flash sync options in different modes.

  • Odi Jamir February 8, 2007 02:34 am

    New at this, just got my first DSLR (d70s) Any Nikon users that can point out how to set rear or front curtain synch on the d70s?

  • Desiree February 7, 2007 03:45 am

    smokingmonkey, would you mind explaining exactly how you got that shot? Looks great! Desiree

  • Sanjay Shetty February 2, 2007 01:21 am

    Thanks for the really simple and lucid explanation.

  • matt January 20, 2007 07:53 am

    this is one of my favorite ways to shoot. :)

  • NAT January 19, 2007 05:00 pm

    This is very useful information, thanks so much. I have got to try this soon. -NAT

  • Sawyer January 19, 2007 12:13 pm

    I can't get Tv or Av to work. Help?

  • Sawyer January 19, 2007 12:12 pm

    When I turn on the flash on on my Canon Rebel XTi, the shutter speed automatically moves to 1/100 or 1/200, even in manual mode.

  • Jonas January 19, 2007 09:29 am

    Great tips, just had a couple of tests, and it does create a nice effect. Never knew what that setting was for, now I know. Thanks!

  • Randy January 19, 2007 05:32 am

    Thanks for the great tips. This is very helpful.

  • KJC January 19, 2007 03:51 am

    Robert: The Digital Rebel XT has a Night Portrait option and you can also use Av (aperture priority). To set 1st (front) or 2nd (rear) shutter curtain sync, see the custom function setting of the manual (p. 150).

  • Robert January 18, 2007 05:11 pm

    Another name I've heard for this technique is "open flash."

    As far as the front and rear curtain sync, how can I control when the flash fires on a Rebel XT?

  • Brian Auer January 18, 2007 12:32 pm

    Totally cool, THIS is the type of stuff that makes me want to get out there and fill up my memory cards.

  • Matthew Miller January 18, 2007 12:26 pm

    Rear curtain sync generally gives the more natural effect, but if you're shooting with a timed shutter speed (instead of bulb mode, where the exposure ends when you say it ends), it's really hard to judge when the flash is going to go off -- imagine if your camera had a two-second shutter lag.

  • Donncha O Caoimh January 18, 2007 08:07 am

    On a 400D you could try either AV/TV or manual modes. Manual is probably the best one to go for because you can adjust the speed and aperture.
    Try a speed of about 1/4 second to get a nice blur on moving people or animals in your image!

  • Dave January 18, 2007 07:07 am

    fantastic tut, any idea on where these settings are on a 400D ?

  • Filipe Rocha January 18, 2007 04:51 am

    I was looking for some information to give to a friend of mine about how to use ISO/ASA in her camera because it was much better to provide her with rather new information than the one I had on a book by Michael Langford, "The step by step book of photography", and I've found dPS. What a great site.
    Already subscribed.
    Looks like I'll be using my camera more often. Or even buy a new one.

    Thank you,

  • Markku January 18, 2007 04:47 am

    Thanks for tip, I bought new flash this week for some project, but flash is more usefull...

  • Donncha O Caoimh January 18, 2007 02:46 am

    I just love that technique and as luck would have it I posted a picture of swans in a local pond yesterday using a long exposure and flash. Love the movement and they look a lot more menacing! (in case the above link gets eaten by a filter)
