Photography is divided into many genres. Some are more popular, some less. But definitely one of the most fascinating is the macro photography. The ability to photograph the microcosm around us in detail unobtainable for an unbridled eye is exciting and very fruitful. Sooner or later, in each of us a desire to shoot whether an insect, whether an unusual plant (flower), but very often results are not what we expected and hoped to get. Every keen enthusiast in macro photography wants to achieve results like experienced professionals. To catch an insect shot under a huge magnification so as to see the faces of his eyes or just to shoot in an unusual way a familiar object of our daily life. In today’s article, we’ll look at what professionals are using, what are the ways to make interesting macro shots and how less we can achieve impressive results.
First, let’s start with what is macro photography? Macro or micro photography is a process of shooting small subjects with a large magnification (usually 1: 4 or greater). For this purpose, lenses are used that focus more closely from the standard and design a larger image on the sensor. True macro photography is when real size increases. Ie. if you shoot a 24mm object, it will be projected to the same size on the sensor (hence the 1: 1 mark).
Since most modern cameras are high-resolution, and with the help of macro lenses they capture very good detail, when the image is printed in large size or monitored on the monitor, the visible magnification may look more than 1: 1. If we assume that we have a perfect lens (no optical defects) and shoot the same object sequentially with two cameras, one of which is 12MP and the other 48MP, the second one will give a seemingly double zoom, but from an optical point of view the increase of the object Both pictures will be 1: 1.
Another way to achieve a larger apparent increase is if we use a macro lens on a camera with a smaller sensor. Since the lens’s minimum objective distance will be the same, the increase is directly proportional to the crosp factor, i. E. if we put a macro lens with a 1: 1 approximation of the m4 / 3 sensor with a 2x factor, we will have a 2: 1 approximation. Taking advantage of this, Olympus and Panasonic make their lenses with 1: 2 optical zoom instead of 1: 1. In this article, however, we will generally abstain from the resolution and the size of the sensor and talk about the purely optical zoom.
In general, when it comes to magnifications in macro photography, it is only the size of the lens-shaped image on the matrix (ie the optical zoom), not the apparent coming from the larger resolution or the size of the sensor.
