text: A wide aperture (lower number) lets in more light and yields a blurrier background, while a narrow aperture (higher number) lets in less light and yields a sharper background.
text: The presence of these two opposing factors implies a point at which the combined blur spot is minimized (Gibson 1975, 64); at that point, the f -number is optimal for image sharpness, for this given depth of field – a wider aperture (lower f-number) causes more defocus, while a narrower aperture (higher f-number) causes more diffraction.
