The basics of using a camera

Although there are thousands of different models and brands of cameras, the operation of all cameras is mainly based on the use of three settings.

When starting out, it is important to understand the meaning of these three settings. At the beginning, it can be challenging to understand how these work, but continuous practice in this matter will produce a positive result.

The first setting: the opening, or "aperture", is marked with the letter F on the camera. F.

This setting determines the size of the camera's aperture, and adjusting it makes the aperture either large or small. The size of the aperture determines the amount of light that hits the camera sensor. Below is an example of how changing the aperture affects the operation of the lens:
Second setting to remember: the shutter speed is marked on the camera with two numbers in the following way: 1/125 or 1/200 for example - the numbers can be smaller or bigger depending on the shooting style. The shutter speed tells you how long the lens is open before it closes and takes the picture. The longer the lens is open when taking a picture, the more light gets into the picture.

At the beginning, it is good to adjust the shutter speed according to an easy rule of thumb: whether it is a lens with a 50mm or 200m focal length, multiply it by two. When using a classic 50mm lens, the shutter speed would be 50×2=100=1/100.

In all its simplicity, the shutter speed works like this: the bigger the number, the faster the shutter speed and the sharper the image. A small shutter speed, such as 1/4 takes in light for a long time, which gives the photos special effects such as these:
Creating the photo

In addition to the camera three important components are required to create a photograph: the light, the object and composition.

The image is not transmitted to the camera without light - light has a very big effect on the quality of the image.
The type and position of the light source in relation to the subject to be photographed affects the style of the image and the kind of feeling conveyed by the photo. For example, a direct light creates a so-called "flat light" style image, which mostly creates a simpler image without shadows.

Varjot muodostavat kuviin syvyyttä, joka ei aina välity ”flat light” -tekniikalla. Alla kerron hienosta kuvaustyylistä, joka pohjautuu 1600-luvulla syntyneen taidemaalari Rembrandt Harmeszoon van Rijn:in maalaustyyliin. Tämä kuvaustyyli soveltuu muotokuviin.

Below are three examples of the Rembrandt lighting technique, where light and shadows form a triangular point of light under one of the eyes.
