Selecting the optimal aperture

The ability to effectively use an existing lens has a much greater impact on the sharpness of the photo than the choice of the lens itself. The aperture number is the most important of the shooting parameters that affect the technical quality of the image. The difference between different aperture values of the same lens may be much more noticeable than the difference between different lenses at the same aperture.

Aperture f / 1.8 f/1.8
Aperture f/2.8 f/2.8
Aperture f/4 f/4 Continue reading

Sharpness
Is sharpness important for a good photo? Yes and no. On the one hand, a technically perfect photo should usually be definitely sharp. No matter how interesting it may be…
