One of the selection criteria when buying a smartphone is the presence of a camera. At the same time, it is important to check the quality of the resulting images so that the purchase is truly enjoyable.
It is not difficult to test a smartphone camera on your own and evaluate the quality of shooting. This can be done using several indicators.
Shooting speed
It is very easy to check the shooting speed. Launch the camera, point it at the object, touch the touch screen once to focus, and then press “Capture”.
A touch screen is a monitor (display) that is designed to enter information by touching certain areas on it.
Thus, the answers to several questions will immediately become known: how quickly did the focusing go, whether the shutter quickly worked, how long did the application take to load. By checking several smartphones, you can definitely feel the difference between them.
Autofocus
Having autofocus in a smartphone is essential.
Autofocus allows you to focus the lens in automatic mode without mechanical adjustments. Some cameras focus the lens both in the center of the frame and on adjacent objects (multi-point focusing).
Therefore, do not forget to test the correctness of this function. When you point your smartphone camera at an object, it should focus on its own, and also quickly and accurately. If on a smartphone the camera misses, then aims and misses again, then it would be best to put that smartphone aside. Such cameras have become obsolete for a long time.
Flash
It is impossible to choose a smartphone based on the camera and not test the flash. The flash must have auto and on modes. Most smartphones in the specifications also indicate that the flash is LED.
The advantages of LED flash include small size, lower power consumption and continuous operation. The latter plays an important role in video filming.
It usually looks like a white dot next to the camera's eye. Smartphones with other types of flashes are practically not produced anymore.
Image clarity
The sharpness of the picture is best checked on a white A4 sheet with small print.
The settings for saving the image greatly affect the clarity of the image. Most often, digital cameras on smartphones save photos in a compressed form using the JPEG format.
Place the sheet on any surface and try to photograph it in its entirety. After that, you should open the photo and enlarge it, if the text is fully clear and easy to read, then the camera meets the necessary criteria.
