What Is My Camera's Flash Sync Speed
This is a guide covering everything you lot demand to know about flash sync speed.
What is Flash Sync Speed?
The wink sync is the fastest shutter speed that you can use along with the flash. Information technology'southward how fast your sync speed can friction match your flash, peculiarly when using cameras with a focal plane shutter.
Near modern cameras volition have two separate shutter blades that become across your photographic camera'due south sensor, effectively exposing it confronting the low-cal.
Since both of these blades become across the photographic camera's moving-picture show, information technology will prevent your flash from fully affecting the camera's sensor.
The short blast of flash can just touch the camera sensor if it'south fully opened during this brief moment.
Nevertheless, the arrangement changes if you lot are shooting at a fast shutter speed. The shutters aren't fully open. Instead of the shutter blades going beyond the sensor 1 past one, they instead "hunt" each other.
This simultaneous movement of both of these blades will create a small opening/slit that looks like to the light when scanning documents. This only allows a fraction of the image sensor to exist revealed at whatsoever moment.
If you shoot at a high shutter speed but only use a flash that only fires once, the shutter will block a flake of it. Creating an unflattering dark line/band across your image.

Wink Sync Speed & High Speed Sync explained
What Does Flash Sync Mean?
Flash sync is a computer-controlled system that synchronizes your wink and shutter release. This allows the flash output to illuminate your subject at a specific fourth dimension.
This volition make the flash evenly expose the image sensor. The flash imitates constant low-cal by flashing multiple times, rather than flashing once and resulting in an unevenly lit image.
The flash sync meaning is essentially how fast your shutter speed should be when compared to the flash. Every camera has its own limitations, for instance:
- The Nikon D610 has its max flash sync speed of 1/200 seconds
- The Nikon 7200 has its max wink sync speed at 1/250
Most cameras volition normally have their max wink sync speed at i/200 seconds up to one/350, but it'south most common at one/200 and ane/250. Unless you have those one-time medium format cameras (Hasselblad, Fujifilm GFX 50R, Pentax 645Z, etc) that employ a leaf shutter.
Photographers that own cameras with a leaf shutter will virtually likely utilize it in a studio or similar location.
Since the shutter is congenital into the lens and not your camera, it operates more like an discontinuity.
The leaf shutter may not be as fast as its focal plane blood brother, but information technology can operate with flashes optimally and at higher shutter speeds.
All of the available shutter speeds tin exist used by the leafage shutter, from the common 1/200 seconds to the high 1/1600 second sync speed.
Why Flash Sync Speed Matters?
The wink sync speed truly matters if yous are planning to shoot using a flash. Which is 1 of the things you are most likely to do if you shoot objects.
It really makes sense if you connect information technology to the exposure triangle (aperture, shutter speed, and ISO).
The moment you try to increase your shutter speed, you'll realize that information technology tends to get darker each fourth dimension. Just, at the same time, it allows you lot to capture fast-moving objects or subjects that aren't still.
Your aperture will also work in a similar way. The smaller your aperture is, (particularly at f/5.half dozen, f/8.0, f/16) the darker your ambience light becomes.
The exposure triangle will adjust the exposure of your scene'south ambient lighting. Using your wink won't alter the scene'southward ambient lite, information technology volition merely add the brightness of your subjects.
Flash sync matters when using a flash, since in that location is a limit to your shutter speed when using a wink. That limit is generally chosen the camera'southward native sync.
Flash sync speed matters even more if you're shooting outdoors in bright conditions. High-speed sync is useful for situations where you lot want a shallower depth of field when using a flash outdoors.
So, permit'due south learn more about this high-speed sync that is commonly on your on-camera flash.
What Happens When You Use a Shutter Speed Faster Than Sync Speed?
Blackness bands are the result of your shutter curtain blocking a part of the image during the exposure. This is what happens when you use shutter speeds higher than the sync speed.
A studio strobe/flash is instantaneous, which instantly makes the image brighter. Sadly this is merely useful if your shutter speed is under 1/200 seconds.
If your shutter curtain isn't fully opened when the strobe flashes, you lot'll become these unflattering, weird, and annoying black bands.
These bands are the main reason sync speed is used, which is why photographers tend to shoot below or at the flashes sync speed.
Using a slower shutter speed normally won't matter to the exposure if you lot're using a wink. The ambience lite volition become so depression that information technology just doesn't register.
Unless, if you make it likewise irksome, like a second or longer. Shutter speeds that last longer than one second will definitely affect how your photos look. Either it is from the changes of the white residuum or the ambience light taken in from the sources of low-cal.
Peradventure a little fun fact too. Have you ever wondered why these black bands get-go actualization from the bottom and climb up if the shutter is really moving from pinnacle to bottom?
This trouble is linked to how your image is actually upside downwards and backward.
When the image hits your sensor or film, y'all will view it from the right side up, and the correct way effectually. All thanks to your photographic camera's built-in prism.
Luckily, once y'all experience this petty black band incident you'll probable never repeat it once again in the future.

Understanding Flash Sync Speed and Loftier Sync Speed
Do You lot Need Loftier-Speed Sync Flash?
A high-speed sync flash is useful for situations where you desire to use shutter speeds faster than your photographic camera'southward native flash sync speed.
This characteristic is highly benign for situations where y'all have an extremely bright background and a subject area in the shade. So, it naturally became particularly useful for outdoor portrait photographers.
I as well recommend using a wider aperture for this. The feature itself saves you time from using ND filters and going through all the hassle with it.
Call back the photographic camera'southward mantle/shutter mechanic I explained earlier in this article? Well, that is linked to how useful a loftier-speed sync flash is.
When a fast shutter speed is used, the curtain will follow each other, only allowing the paradigm sensor to be exposed bit by bit.
Using a high-speed sync flash, the flash will "pop" multiple times to properly expose the prototype sensor with the flash.
This is achieved by using a photographic camera capable of high-speed flash sync and a defended flash. The remainder of the chore is simply setting upwardly your camera and flash accordingly.
Unfortunately, one of the drawbacks of a high-speed sync flash is its range. The more than you increase your shutter speed, your flashes constructive range will reduce significantly.
Professional photographers will often accept multiple powerful light sources and power packs, some would likewise recommend beamers. Y'all may desire to bring boosted lights depending on the setting, subject altitude, and lighting conditions.
This characteristic will give you more artistic control over your images whether your camera is in automatic, manual, or aperture manner.
How Practise You Sync Wink with Shutter Speed?
On most cameras, you can easily set up your flash for a high sync speed by going to the custom settings menu.
Search for the bracketing/flash, and you'll be greeted with various options of flash sync speeds.
Choose your desired flash speed, which will either be ane/200, ane/250, or 1/320 seconds depending on your camera's native sync speed.
This will not make your camera and wink strictly synchronized in the selected sync speed. It actually ways that both your camera and flash will sync at any shutter speed that your camera offers.
These are the basics, which usually apply to most cameras. But just to be sure, delight check your camera'due south instructions.
Some cameras such every bit the D700 and higher Speedlights offer high-speed sync.
Lastly, to ostend your chosen flash sync speed, there'll exist the letters FP on your Speedlights LCD. These letters indicate that your camera and flash are both in HSS way.
Let me wrap upwards today'southward topic:
- And then, what is wink sync speed? Information technology's the speed where both your camera and flash speed can work in tandem to produce an evenly exposed prototype.
- Medium format cameras such as the Hasselblad won't confront this consequence since their shutter system is within their camera. This allows the camera to have a wink sync speed upwardly to i/1600.
- Flash sync pregnant is basically the limits of your camera's native shutter speed can work with your strobe/Speedlight. Without a properly prepare wink sync, you're likely to accept blackness bands on the bottom of your image.
- Flash speed matters the most when photographing outdoors and peculiarly when the sun is quite bright. By adjusting your flash sync speed, yous can hands take images that aren't overexposed easily. All without needing to fiddle and refocus your camera with the ND Filters.
- A high sync-speed wink simply matters if you're shooting with a flash (obviously). Notwithstanding, they are particularly useful when you lot have your discipline in the shade but at the same time have a very bright groundwork.
- You lot can easily ready the wink by going to the custom settings carte, select bracketing/flash, and merely select the desired flash sync speed. Information technology varies between models, but the maximum would probably be 1/200, 1/250, or 1/320 seconds.
- Since fast shutter speeds make your shutter mantle move simultaneously, information technology creates a little gap between themselves for calorie-free to enter. If the image sensor isn't evenly lit during this moment by multiple flashes, then the black bands will announced.
- You can easily prevent these blackness bands past using a slower shutter speed or using a camera capable of high sync speed flash.
That's pretty much it! The concept may be hard to assimilate at first, but it gets easier once you know how the shutter curtain works. HSS wink is peculiarly useful for outdoor photographers that shoot in vivid environments. Proceed practicing and good luck!
