If you have not seen the use of high-speed flash for outdoor portrait photography or any other kind of photography, then today is the day you learn everything about it. We will discuss the details for high speed flash for photography and its impact on outdoor portraits.
What is the normal sync speed for a flash?
The normal sync speed for a flash is typically around 1/200 to 1/250 seconds. This is the fastest shutter speed at which the entire image sensor is exposed simultaneously, allowing proper synchronization with the flash to capture well-exposed images.
What is High-Speed Flash for Outdoor Photography?
High-Speed Sync is something that allows you to use your flash at shutter speeds of more than 1/200 of a second. This is the typical flash sync speed on most digital cameras. With HSS, you can be exposed to a dramatic sky while still getting good exposure to the subject. An outdoor portrait can be drastically changed by high speed sync. The amount of ambient light that a camera captures is determined by the shutter speed.
High Speed Sync operates by rapidly pulsing the flash, making it appear to be on continuously. The HSS mode forces the flash to remain on at high shutter speeds for the duration of the open shutter. In outdoor flash photography, shutter speed with flash does play a significant role if there is ambient lighting. The shutter speed and ISO have an impact on the brightness of the background. Aperture and ISO govern the exposure of the subject lighted by the flash.
This technique allows the creation of beautifully exposed outdoor photographs. It forms a background that is blurry without blowing out the highlights. In this regard, high-speed sync allows the flash to adjust according to the external light. The composition is perfectly formed with a suitably illuminated subject.
Portrait photography aims at capturing the personality, character, and emotions. It can either be candid or artistic. Portrait photography requires more than just the ability to understand your camera settings, lighting, and composition.
You must also possess the ability to connect with your subjects and capture their unique qualities. So, it is a difficult but rewarding genre of photography.

What Is Sync Speed?
The fastest shutter speed at which the camera can simultaneously expose the entire frame is known as the sync speed. In this, the first shutter curtain fully opens when any shot is fired below the sync speed. It exposes the entire sensor to light. The second shutter curtain glides across the frame to complete the capture at the end of the exposure period.
The use of high-speed sync is crucial when using flash outdoors. You can only use shutter speeds below the sync speed or at the same sync of the camera if HSS is not used. To check the sync speed, you can see the owner’s manual for your specific camera. It will help you find a way to brighten the backdrop in this scenario. You just need to slow down the shutter speed. Conversely, you can make the background darker by speeding it up.
In order to control the backdrop when utilizing high-speed flash outdoors, you must match the brightness of your light source to the required aperture. Your options in adapting to changing lighting conditions are drastically reduced if you are constrained to the native flash sync speed of your camera. You have several possibilities with high-speed sync.

Speedlight and High-Speed Flash
Speedlights are great to control flash if you are taking portraits outdoors. High-Speed Sync is a flash setting that causes the Speedlight to quickly burst into action. It guarantees to light up the subject with flash. In other words, the flash is pulsating so quickly that it appears to be a single flash. It lights up the scene at 1/8000. You can position your flash at interesting angles to your subject using a wireless transmitter to create lovely light.
The sensor always captures flash illuminating the subject, regardless of how quickly the shutter curtains move. Using a speedlight, enough light can be put on a subject using one speedlight in HSS and shooting at 1/2000 in the middle of the day. The simplicity and portability of speedlights is the main benefit of using HSS with them. The drawback of using HSS with a speedlight is the reduced power output, which is significant.
