Blur out the Distractions by Using a Large Aperture
Patrick Ryan McCann believes a large aperture to be your best friend in fitness photography. The optimal aperture, according to him, is f/1.2 or f/2.8. Having a large aperture is that the background will appear as blurrier as the number size.
According to Patrick Ryan McCann, your shooting style determines the aperture. In order to blur out the distractions, an aperture of f/2.8 is enough to capture the details on a model's face perfectly. To find the perfect blur/sharpness ratio, Patrick Ryan McCann suggests experimenting with various apertures.
