Principles of photography include.. German experts’ advice for those interested in variable-lens cameras
The German Product and Goods Testing Authority has advised photography enthusiasts to familiarize themselves with the various settings options offered by variable-lens cameras, so that they can creatively ‘paint with light’.
In the beginning, beginners can leave the task of adjusting the relationship between the aperture and exposure time of the camera to be adjusted automatically, so as not to lose the passion for photography; Since it is somewhat complicated for beginners, to do this the German authority advised to set the program to the P mode of the program’s automatic mode.
Exposure is the amount of light that is allowed to fall onto the photographic medium, whether it is the photographic film in conventional cameras or the image sensor in digital cameras, during the process of capturing the image.
In the case of automatic adjustment, the camera suggests the amount of aperture and exposure time, and the photographer can adjust them, and the camera adjusts the light sensitivity index known as ISO and the white balance of the color temperature automatically, in addition to that, the brightness of the image can be corrected by exposure correction function.
Examples that are worth resetting the brightness when photographing bright objects in a dark environment include; As this leads to excessive exposure due to high contrast, and in such cases it is possible to use the exposure correction function, to darken the image slightly by two levels, for example.
And if the photographer wants to take portraits – portraits of people, in which the background is blurred, then he must take pictures with a large aperture, which corresponds to the lowest possible focal number, and the exposure time should not be too long, so that there is no distortion in the the face.
And when you take pictures of fast motions and the exposure time is too long, this will lead to blurring of the subject, and one of the important things here is to freeze the movement in question by using the shortest possible exposure time.
The following is an illustration of the common abbreviations on the left-hand wheel for variable-lens cameras:
M (Manual mode): This mode allows the photographer to manually adjust the aperture, exposure time, ISO number and many other settings.
S (Shutter – Time Preset): This mode allows only the exposure time to be set, at which time the camera selects the appropriate aperture.
A (Aperture – Preselection of aperture): This mode allows you to adjust the aperture only, and the camera selects the appropriate exposure time.
iA (Intelligent Auto): In this mode, the aperture, exposure time, and ISO number are determined automatically, and these settings cannot be modified.
C1.2 (User settings): Here the user can store his own settings, which are used most often, and can be called directly.
There is another rotating wheel on the right side of the variable-lens cameras, and it is used to change the settings mentioned previously, and there are often small buttons for adjusting the modes of adjusting the exposure correction function (+/-), white balance (WB) and light sensitivity.
