When photographing moving objects, it is possible to ‘stop’ them with the help of a photograph and see all the dynamics of movement at ‘stop pause’. Such pictures almost always look very interesting and unusual, since in real time the human eye does not see what can be seen in the freeze frame.
The easiest way to get ‘freeze’ or ‘stop‘ motion in photos is to use slow shutter speeds. Short shutter speed means that the subject is locked for one short moment. The easiest way to achieve a short shutter speed is to shoot in shutter priority mode. This mode is usually referred to as ‘S’ or ‘TV’. For the maximum effect of stopping time, just select the minimum possible shutter speed. For modern SLR cameras, this shutter speed is usually 1/4000 s or 1/8000 s. In this mode, the time in fractions of a second is set, during which the image will be fixed.
Such a simple method works very well when there is a lot of light and / or when it is possible to use a fast lens. For example, in the image above, ISO 100 and F / 1.8 were enough to get a short shutter speed of 1/800 second and freeze the moth’s flight. But most often it’s not enough light, the lens doesn’t have high aperture. Therefore, to achieve the effect of stopping time, you should increase the ISO values. Continue reading
The ISO value is one of the most important settings when shooting, along with such values as shutter speed, aperture, and white balance. ISO is also often referred to as ISO sensitivity, ISO level, or simply the photosensitivity of a matrix or film.
Still, what is ISO in the settings of the camera?
ISO is a parameter indicating the level of sensitivity to light of its light-picking element (matrix or film). Basically indicate the limits of ISO for cameras (cameras). Although, the same parameter can be found not only on the camera, but, for example, on the flash. For a flash, a guide number is usually indicated when using one of the ISO values of 100, or 200. ISO sensitivity is indicated in special units of the ISO system. The ISO numeric expression itself can accept any integer expression from 1 to infinity. For example, on my SB-900, you can set the ISO from 1 (unit) to 12,500, and on my Nikon D40 you can set the ISO value from 200 to 1,600. Continue reading
Aperture is easy. In a nutshell, the diaphragm is a device in the lens that measures the amount of light.

For a better understanding of the operation of such a device, I will give an example from life. When people look at the sun, they squint their eyes, that is, they reduce the gap through which light passes. If people had not squinted, the sun would have burned the retina of their eyes with their strong light. At night, you need to do the opposite – open your eyes wider to capture more light, while the pupils also expand. Eyes with large pupils have many animals that need to see well at night.
Often the aperture is also called ‘aperture’ or ‘aperture’ or ‘relative aperture’ or ‘number F‘. These concepts are strongly interconnected and for many photographers are synonymous. But among them there are small differences described below. Continue reading
Shutter speed is the time that the camera captures the image. When photographing, light is read using the camera’s matrix or using a film. When we do not take a picture, the film or matrix is closed by the shutter. During shooting, the shutter opens and the film or matrix receives an image from the lens. The amount of time until the shutter is open and there is an exposure.
No, the article is not about alcohol, the article is about the photographic concept of aging. Exposure is easy. In phones and digital cameras (soap dishes) there is no mechanical shutter as such. There, the shutter is the on / off matrix. But the principle of operation is fully preserved with the only difference, instead of raising the mirror and the shutter curtains, the soap dish matrix is simply updated. Now fashionable mirrorless cameras, for example Sony ILCE-7 do not have a mirror, but they have a real mechanical shutter, which gives that very nice click of the shutter.

1. Photographer – the main element during photography. If there weren’t a person, the camera wouldn’t turn on, would not be installed in the correct position near the model or landscape, would not focus and would not take a picture at all. The photographer manages the entire shooting process, he is fully responsible for the shooting process, is responsible for the result, and no go-ahead is acceptable. If someone called himself a photographer, he should be able to take pictures and get excellent results even on a phone, a soap dish and a tin can. And this requires much more than just picking up a camera and pressing a button.
But, of course, a person himself cannot control everything, because the next factor that affects the creation of photography, I will name the external factors. Continue reading
