Using High-Speed Sync Flash in the Afternoon Sun

Using High-Speed Sync Flash at High Shutter Speed-  with Canon Speedlite 430EX III-RT with Diffuser

Overpowering the sun and wind with High-Speed Sync (HSS) Flash

Outside close-up and macro photography is generally done on an early windless morning with crisp light / or with some cloud cover for reducing harsh light and glare.

But, what do you do if you only have 14:00 in full afternoon sun and the wind is blowing? Suddenly a high shutter speed and using flash is more than a suitable solution.

I went out at 14:00 in the sun for deliberately capturing a yellow (and very bright) flower against (my own) close-up and macro photography principles.

In using a Speedlite (external flash unit) fitted in the camera flash hot shoe and applying the Speedlite's High-Sync Speed (HSS) setting I was able to overcome the maximum sync speed (highest shutter speed of a particular camera when using flash) of the camera I was using - 1/250s on the Canon EOS 70D - by setting the shutter speed to whatever I wanted higher than the 1/250s limitation.

Most entry-level DSLR's are capable of 1/4000s Shutter Speed and enthusiast / professional cameras up to 1/8000s.

For this image I experimented (handheld) and went up to the maximum (almost unthinkable) shutter speed of 1/8000s of said camera - maybe a stop or two too high of what was actually required, but nevertheless, together with the flash, overpowered the sun and stopped the plucky wind from blurring the flower.

One of the applications of HSS is to be able to use wide apertures with faster shutter speeds for limiting the available ambient light (i.e. sunlight in this case). The faster the shutter speed the more the ambient light limitation. HSS is only available to use with either the camera's pop-up flash or with an external Speedlite flash.

In early morning close-up and macro photography (outside) I will use Aperture Priority Mode at whatever aperture is required (by me) and hardly be bothered with the shutter speed - and most often without flash.

Settings for this experimental image: Manual Mode @ ISO 400 / f/5.6 / 1/8000s with Canon EOS 70D / Speedlite 430EX III-RT with stofen-type plastic diffuser (flash head +- 35% tilted upwards from default position).

Lens used: Canon EF 70-300mm f/4-5.6L IS USM lens

Speedlite Mode: E-TTL (with no exposure compensation)

Image is uncropped and slightly processed in Adobe Lightroom Classic CC 9.

Using flash is therefore not only for adding light to low ambient light conditions, but also for limiting / overpowering strong sun light.

Birds in Flight Photography. Grey heron in early morning light... 

The heron was captured with an (almost) entry-level Canon EOS 700D and 1st generation EF 70-300mm lens at Woodbridge Island.

Taking advantage of good light
Grey Heron in Flight over the Milnerton Lagoon, Woodbridge Island

Its not always about having the fastest camera / (longest) lens combination, for me, at the time, the quality of light was the most important criteria. A fast shutter speed came in handy as well. This is a JPG image straight out of camera with minimal cropping (if any).

The image was captured on an typical African summer's morning, but still very early in the morning (less than an hour after sun rise). Seeing a grey heron so close was really unexpected, but with its relatively slow flight speed I had enough time to adjust the zoom for an almost full frame capture.

The small aperture used / and the fact that the bird was so close to the background did not provide for any background blur in the image, but at least the f/9.5 aperture provided for a relativity sharp subject.

Photographers new to Canon Flash also welcome to attend
You don't necessarily have to own a Canon Speedlite flash for attending this training. Many of the flash technologies in Canon Speedlite flashes are also embedded in the pop-up / built-in flash on any APS-C Canon EOS DSLR (i.e. E-TTL / Manual Modes / Flash Exposure).

The pop-up / built-in flash settings are accessible and controlled via the flash control settings in the red menu section of most of the latest Canon EOS DSLR bodies.

The understanding and management of Canon flash properties are the same and the private training / workshop will provide a good opportunity for new photographers to learn how to apply ETT-L (II) / Manual Flash Modes for application in low light photography and / or other (indoor / outdoor) creative exposures.

Canon Speedlite flash provides various on and off-camera opportunities for improving / manipulating light(ing) conditions, but the fundamental flash and ambient light principles are the same.

All standard Canon exposure modes [Program (P) / Aperture Priority (Av) / Shutter Priority (Tv) / Manual (M) Modes] will be referenced throughout the training sessions with regard to Speedlite flash / ambient light(ing) strategies ito:
  • ISO
  • Aperture
  • Shutter Speed
