Flash photography tip: Use your flash sync speed on sunny days

A good starting point on a sunny day is to set your shutter speed to your camera's flash sync speed. This allows you to open your aperture a little further, so your flash does not have to work as hard.

Krijn

Krijn - f/4, 1/250s, 100 ISO @ 95mm

Another advantage is that your depth of field can become smaller (larger aperture opening). The background in these photos will then be slightly more blurred. For portraits, that is usually a plus point.

On most cameras, the flash sync speed is often 1/200s or 1/250s. You can always look this up in the manual or with a Google search. It is useful to know where the limit is for your camera.

    Hello Elja, I don't quite understand this. On a sunny day, at 1/250 second I already end up with a fairly small aperture. Even at ISO 100. So a fairly large depth of field, which is often not the intention with a portrait. Of course I do understand that you use the flash for fill-in.

    It of course really depends on the situation. If I point my camera outside now, I get f/11 at 1/250s and ISO 100. I usually look for a spot in the shade, though, so then you quickly end up at, for example, f/4.

    I also mean here that you would use your flash to light your subject. So not fill flash.

    A bit of a strange title... on a sunny day... but you go into the shade yourself or in this case under a tunnel or something to keep your aperture low, if you do this outside in the sun your story can never be right except when you would use a grey filter.

    I agree with you that it could have been clearer. vrolijk
    In the sun, you won't manage these shutter speeds, indeed. Maybe at f/22.
