text: If you’re shooting in lower light you’d probably want a wider aperture (which is a lower f-number).
text: Choosing small apertures (high f-numbers) and slow shutter speeds is, speaking strictly in terms of exposure, the same as choosing larger apertures (low f-numbers) and fast shutter speeds.
text: Basically, a larger aperture (lower f/number) will have your subject in focus, and everything in front of and behind it blurry.
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.
