How to use autofocus

Autofocus or autofocus for most photographic scenes is the preferred solution over manual focus. In skilled hands, autofocus focuses more precisely, and, most importantly, faster than the average photographer. However, autofocus is far from being as simple as it might seem to a novice amateur photographer, and its proper use is very far from the point-and-shoot principle. There are a number of subtleties that you should learn if you want autofocus to stop living its own life and begin to do what you want from it.

I highly recommend that you re-read that section of the manual for your camera that focuses on autofocus – these are some of the most useful pages in the entire manual, and the information contained therein should not be neglected. At a minimum, you should be aware of which controls are responsible for switching between different autofocus modes and choosing the focus point you need. Continue reading

Starry sky

Many people who admire the starry sky on a clear night have a desire to photograph the sight they saw. Unfortunately, these attempts are far from always crowned with success, especially since a person who is accustomed to photographing exclusively during the day with an excess of light is often unclear on which side to approach the shooting in such seemingly unfavorable conditions. Nevertheless, to get a beautiful night shot with saturated colors, clearly visible constellations and a whitish strip of the Milky Way crossing the sky is easier than it might seem at first, and in this article I will try to make it possible to highlight the practical side of the issue. I note that we will not focus on high astrophotography, but rather on ordinary shooting of the starry sky in the context of landscape photography. Detailed shooting of deep space objects (galaxies, nebulae, quasars, etc.) requires very specific skills and tools, while decorating the night landscape with the general plan of the Milky Way is possible for everyone.

Diffraction

Diffraction is an optical phenomenon that limits the sharpness of a photograph while reducing the relative aperture of the lens. Unlike other optical aberrations, diffraction is fundamentally unremovable, universal and equally common to all photographic lenses without exception, regardless of their quality and cost.

Diffraction can only be seen at 100% magnification. Notice how the image becomes less and less sharp with increasing aperture.
With the passage of light through the aperture, the bulk of the light waves continues to move rectilinearly. However, those waves whose path lies near the very edge of the diaphragm deviate from their original direction, trying to go around the obstacle that has arisen on their way. The smaller the size of the aperture Continue reading

Shutter speed or, as it is also called, shutter speed is directly related to the transmission of motion in the pictures. When shooting stationary objects with a fixed camera, shutter…

Good shots in low light
Taking regular photographs in natural light is not difficult to notice that truly good light (not plentiful, namely good) is a disappointingly rare phenomenon. Let's be honest: beautiful lighting lasts…
