The Dhaka Times Desk With the advent of new smartphones, new features are coming along with the modernity. Nowadays, mobile companies have to look at powerful RAM and long-lasting batteries as well as advanced cameras.
While buying a mobile phone, it is very important to look at various things like storage, display, camera. But most people look at the camera details while buying a smartphone. Many people don't know what camera features to look for in a good camera.
Many a times it is seen that the image quality is not very good even with 50 megapixel camera. Again, a premium phone like iPhone is given only 12 megapixel camera. But how good is the quality of his pictures. This is due to other components of the camera. So, find out today which aspects of the camera should be taken care of while buying a smartphone.
Sensor and its size
Basically the sensor is the most important part of the camera. The larger the sensor size, the more light there is. Larger sensors can capture more light. Due to which good pictures can be taken even in low light. Overall the picture is good. So make sure the sensor is big. A good sensor will only improve the image color and image sharpness. The biggest sensor used in Xiaomi's new smartphone. Here, the size of the sensor is more important than the megapixels.
Pixels and its size
Pixels block the light that enters the camera. Bigger pixels can also hold more light. Due to which good pictures can be taken even in low-light. Pixels are important for capturing clear images even in low light. Manufacturers like Huawei, Samsung use large pixels in mobile phones.
Aperture
Basically the size of the aperture (f-stop) determines how much light the lens will actually let in. A lower f-stop means a larger aperture and thus better low-light photography.
Image signal processor
Embedded ISPs or image signal processors are also used to process data from camera sensors. It basically affects the image quality too.
Optical image stabilization
We all know that shaking hands while taking pictures can spoil the picture. OIS reduces blur caused by handshakes during photography or videography. That's why cameras that have OIS will take better pictures.
HDR
HDR (also called High Dynamic Range) technology can also capture more detail in images in both bright and dark conditions by combining multiple exposures.
the lens
As we all know the lens quality is very important for a good quality camera. Triple-camera style smartphones were also very popular in the market last year. Quad-camera smartphones are also available at affordable prices. The lens is crucial for capturing ultra-wide-angle and landscape-style images. Reference: Make Use Of.

How to prevent dengue
Dengue is a mosquito-borne viral fever. This fever is different from other viral or bacterial fevers. However, this fever is not contagious in any way. This viral fever can occur alone or in combination with other viruses (chikungunya, yellow fever, Burma forest, flu, respiratory syncytial) and bacteria (pneumococcus).
Dengue fever is divided into two categories depending on the severity of symptoms and fever.
1. Common dengue fever
2. Dengue fever with bleeding.
In the case of common dengue fever, the following symptoms are mainly seen-
1. Sudden high fever lasting 2 to 7 days.
2. Severe headache.
3. Pain behind the eyes.
4. Along with the fever, red rash appears all over the body.
5. Severe pain in whole body as well as back pain.
6. Nausea or vomiting.
7. A rash or red bumps on the skin.
In case of dengue fever with bleeding:
1. Bleeding from nose, mouth or vomiting with high fever within 2 to 48 hours.
2. Fluid accumulation in chest or abdomen along with fever.
If any of these symptoms appear, seek medical attention immediately.
On the other hand
Wait at home for the first 3 days of fever. On the other hand, sponge the whole body with water every now and then. This will reduce the level of fever. Drink enough water and rest. After that, if the fever does not decrease or if it continues to increase after some time, consult a doctor immediately.
Things to do to prevent Dengue:
1. Try to keep the surroundings of the house as clean as possible.
2. If there are flower tubs or broken plastic bottles, can shells, tires or polythene inside the house, clean them quickly and drain the accumulated water from the flower tubs.
3. Spray or fog at least 3 times a week to kill mosquitoes.
4. You can keep mosquito repellent cream with you while going out.
5. After evening, younger and older members of the household should use mosquito nets.
6. Clean up any accumulated rain water, as this is the time when Aedes mosquitoes lay their eggs.
7. On the other hand, you can use mats along with mosquito nets to avoid mosquito infestation.
8. Since Aedes mosquitoes bite during the day, it is important to avoid sleeping with mosquito nets while sleeping during the day. Source: https://dmpnews.org
