Megapixels alone are not enough for a quality picture taken with a mobile phone. You will find out what other parameters are important.
Most people pay attention to the camera when buying a new mobile phone. They need to take photos that will be flawless. According to some research, many first inquire and look at the specifications of the phone, its camera, and the number of pixels. Phones with the largest number of pixels are bought, but knowing that one model of phone has more megapixels than another model does not mean that it will take better photos. Look for a great selection of great features on Amazon.
What makes a photo?
For a good photo, everything is important. One photo is the total number of pixels. That number of pixels is shown in megapixels, and phone manufacturers often point out that figure. In some cases, it does not necessarily mean what is bigger and better. The light makes the photo good, and the sensor in the camera needs light. The sensor has pixels that collect data about light and convert it into electronic form. Pixels on a larger sensor contain better light information. In (µm), the individual pixels on the sensor are measured, and in parts of inches (for example, 1 / 2.3 ”, 1 / 3.06”…), the size of the sensor. The sensors are reduced, and many pixels are placed on them, which is why the registration of light is weak, while the images will have a large amount of noise when the lighting is lower. In the second case, photos with a lot of detail will give more pixels on the sensor in good lighting.
A higher number of pixels gives better detail, while a smaller number of pixels registers light better in the dark.
What is optical zoom for?
You will lose the quality of the photo if you crop the image you took or crochet it. Optical zoom is an option included here and is available on phones with dual cameras whose system is made with one ordinary and one telephoto sensor. Digital zoom is software that zooms the pixels where the quality of the photo is lost. The actual zoom is the optical zoom. Photo quality will not be lost when zooming.
Why is aperture important?
An important parameter for a good photo is the aperture. The number f is the ratio between the aperture size and the focal length. The lighter can pass through the aperture, the smaller the number off, and thus you will get more light falling on the sensor. Shooting in low light with a lower for higher aperture can give great results. With such a relationship, we get the so-called depth of field. A camera with a higher f-number has a wide depth of field and less chromatic aberration. Failed focusing can be caused by chromatic aberration or the side effect that results from the refraction of different wavelengths through different angles.
(Chromatic aberration effects are visible as thin lines of different colors surrounding objects’ edges with high contrast. They are mostly on the outer parts of images.)
The famous bokeh effect represents the depth of field, which is often with a dual camera. One camera will focus on you, and the other will focus on the background and intentionally blur it. You don’t need another camera if you have a camera with a smaller number off. This bokeh effect is perfect for portrait photos.
(Bokeh effect means blur quality. It is caused by the narrow depth of field, which is the distance between the nearest and farthest object in the photo.)
Why is image stabilization important?
Crucial requirements for clear photos and videos are Electronic Image Stabilization (EIS) and Optical Image Stabilization (OIS). How often have you heard it’s a good picture but blurry? That is why the stabilizer is important. Optical stabilization cameras are very complex. This system works by placing the sensor on a stabilization system that takes data from the accelerometer (gyroscope) on the phone’s movements, and such a system electromagnetically keeps the camera stabilized. A simple software system is an electronic stabilization. It will most likely increase the speed of shooting or shooting to reduce blur and register more thumbnails.
