Good autofocus

Lens device
The lens should be considered a key component of an optical device called a camera. That's right: not a matrix, but a lens. A photograph is an image, and nothing…

Lens change

The main advantage of cameras with interchangeable lenses over compact cameras is, as the discerning reader has already guessed, the ability to change lenses. Changing the lens itself is a simple matter and briefly covered in the instructions for any camera. Nevertheless, there are a number of nuances that are not written in the instructions, but which you should take into account if you want to learn how to change lenses quickly, confidently and with minimal risk for photo equipment.

Change the lens should be carried out as quickly as possible. And not only because of the fear of missing out on a spectacular shot while tinkering with technology, but also because of the unwillingness to leave the Continue reading

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

Back button focus

According to an established tradition, autofocus is activated by pressing the shutter button halfway, and pressing it fully releases the shutter. However, it is often much more convenient to separate the shutter release and autofocus. Back-button focusing or back-button focusing is an autofocus control scheme that is not very popular among amateurs, in which autofocus is activated not by the shutter button, but by an independent button on the back of the camera.

Some cameras have a special focus button AF-ON, and some allow you to reprogram the AE-L / AF-L button so that it is responsible for autofocus, and not for exposure lock. 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.

Macro shot

The word “macro photography” usually means photographs taken on a sufficiently large, but still not microscopic scale, i.e. from about 1:10 to 1: 1. Pictures with a scale exceeding 1: 1 are already referred to as microphotographs, and everything smaller than 1:10 is considered just a close-up. The given ranges of scales are very arbitrary, and can serve only as guidelines, and not in any way rigid boundaries between individual genres of photography.
Perhaps the reader does not quite own the concept of scale, and the numbers 1: 1 tell him little about what? There is nothing complicated here. The shooting scale is the ratio of the linear dimensions of the subject to the linear dimensions of its image projected by the lens onto the matrix or film. A 1: 1 scale means full-size Continue reading
