Flash photography tip: Darken your background

By playing with your shutter speed, you can darken the background in your photo. This creates an effect as if you were shooting in the evening or at night, even though you're simply shooting in the middle of the day.

You can also use this to make your background a little darker. It won't look like night, but more attention will go to your subject.

You need to make your shutter speed faster than your camera indicates for this. Suppose the correct exposure with your settings is 1/20th of a second, for example. Then go to 1/160s.

You are effectively underexposing the background by 3 stops. So you'll see your background getting darker while you can still light your subject with your flash.

    Hallo Elja, je schrijft het volgende: 'Door met je sluitertijd te spelen kun je de achtergrond in je foto donker maken. Dat geeft een effect alsof je 's avonds of 's nachts aan het fotograferen bent terwijl je gewoon midden op de dag bezig bent.'

    Nu las ik in een ander artikel van jou dat wanneer je een oranje filter op de flitser zet en de WB instelt op kunstlicht, je ook een nachteffect krijgt, al is de foto overdag genomen.

    Wat is nu de beste methode om dat nachteffect te bereiken?

    In beide gevallen onderbelicht ik de achtergrond. Dus dat is een constante om het nachteffect te krijgen. Bij de versie met het kleurfilter maak ik de achtergrond ook nog blauw.

    Het is verder wat mij betreft een kwestie van smaak.

    1/20e sec lijkt me wat lang om scherpe foto's van mensen te maken. En van 1/20e sec naar 1/160e sec is 8x minder licht, 3 stops, dan wordt de foto wel heel donker. Maar wel n goeie tip
