How to know if you have a good camera when buying a smartphone? These are the things to know

Nowadays, when buying a mobile phone, the first thing that comes to mind is the camera. How is the camera After the trend of taking selfies started, it has been said that mobile is for the camera. Of course, new technologies and high quality cameras are coming to mobile phones. As a result, the obligation to carry other cameras has been removed.

Since professional cameras are not accessible to everyone in Nepal, smartphones with cameras are the choice of many. So today we are giving information on what to look for in a smartphone camera if you are buying a mobile.

Megapixels : Megapixels which is called MP for short. This is a unit for measuring the pixels in a photo generated by a camera. One megapixel equals one million pixels. Which means that a picture taken by a 10 megapixel camera has 10 million pixels.

Generally, the more megapixels, the better the camera. The megapixel cable is just a number. In some cases, a 12-megapixel camera can take better quality photos than an 18-megapixel one. The lens used in the camera also plays an important role than the megapixel.

Sensor size: Sensor size has a big impact on photo quality. The bigger the sensor, the more it can see. Due to which a good photo can be taken. Most smartphones have a sensor size of 0.33 inches, while some smartphones have an average size of about an inch.

The bigger the sensor, the more pixels. If there are two smartphones with equal megapixel camera, but the sensor of one is bigger than the other, then the camera with the size of the sensor provides a better quality shot.

CCD and CMOS (SIMOS): There are two types of sensors used in smartphones. CCD (Charged Coupled Device) and CMOS (Complementary Metal Oxide Semiconductor). Earlier smartphones used CCD while modern smartphones now use high-tech and relatively expensive sensor CMOS.

Apache: Another important element of the camera is the aperture. The aperture is usually denoted by ‘F’. If you have f / 2.0, f / 1.8 If you see this written, it is given information about the aperture of the camera.
The smaller the number, the larger the aperture of the camera, from which more light can enter the camera. If you want to buy a smartphone with a camera that can take great photos even in low light, you should choose a camera with a minimum aperture when choosing a camera.

ISO and shutter speed: ISO and shutter speed are two other important parts of the camera, just like the aperture. The shutter speed is the unit that informs how long the lens of the camera stays open for taking pictures, while the ISO informs how sensitive the light available in the camera is.

The higher the ISO, the more sensitive it is to light. At 100 ISO, it takes 1 second for the camera to take a picture, while at 800 ISO, it takes 0.125 seconds to take a picture. Shutter speed is the time taken by the camera to take a photo.

The user can easily change the shutter speed of the camera. The higher the shutter speed of the camera, the more light the camera can capture, but its weak point is the blurry image when the camera shakes. Low shutter speeds are useful for taking instant photos, while long shutter speeds can be used to take photos, including fireworks, in low light.

Image Stabilization: Image stabilization is to prevent the camera from shaking normally. Image stabilization is about stabilizing the images that come out of the camera without moving it. There are generally two types of image stabilization. Digital image stabilization and optical image stabilization.

The use of software in digital image stabilization technology protects the image from normal shaking, while in optical image stabilization the camera lens is stabilized using mechanical methods. The optical stabilization method is considered to be comparatively better than digital stabilization for taking photos in low light.

HD and Fork (4k) : Another aspect of the camera that the camera user must know is HD and 4K. HD and 4K are measured in terms of camera resolution like megapixels, but it is also associated with video. The full HD version is high definition with 1920 pixels x 1080 lines. Fork, also known as Ultra HD, is exactly double the size of HD, which is 3840 x 2160 lines. In the same way, the DK of Fork is exactly doubled.

This is not good for smartphones with low memory as the memory space occupied by 4K videos is double that of HD. Although many smartphones with 4K resolution video capabilities have come into the market, smartphones with 4K resolution video are rarely found in the market.

And format : Most smartphones save images in JPEG format but some high-end devices save images in ‘and format’. ‘And format’ is considered good for professional photographers. In this format, the image is saved as seen by the sensor of the photo camera, but in JPEG format, the image is saved by optimizing the image. Compared to JPEG format and the image in the format can be easily corrected.

Software and apps: Despite having excellent lenses, camera sensors and stabilized images, the use of bad software and apps can have a detrimental effect on the photos you take. Just as lenses, sensors and stabilization are important, so are software and apps used on smartphones.
