Take care of your camera sensor

 How to clean the camera sensor

Step 1. Find the option to clean the sensor on your camera.

Step 2. Selecting this mode will lock your camera mirror and the sensor will be visible.

Step 3. Then blow the camera sensor with a blower. Make sure that Blair's head does not touch the camera sensor. Thus dust the sensor.

Step 4. Then gently tap it on the sensor with two drops of solution on the swab.

Step 5. Then put on a lens and start taking pictures.

What is in a Camera lens?

This seems a bit difficult to understand theoretically, but in fact it is not so difficult to explain in practice. To understand the function of the lens, we need to understand three things.

1. Focal length
2. Aperture and
3. Shutter speed

Focal length

A 35-millimeter full-frame is generally considered ideal for photography. But due to the very small size of the lens of the smartphone, this frame is a maximum of 26 millimeters in the case of a very good lens in the case of a smartphone. The greater the focal length of a lens, the greater the zoom in the lens. Again, the shorter this focal length, the wider the field view of the lens. Since the normal focal length of our eyes is usually not more than 50 millimeters, if a lens of 50 millimeters is used (not actually used) then the circumference of the image will be the same as the normal vision of our eyes.

Aperture

The basic idea about aperture came up in a previous article. Simply put, the aperture is a way of controlling the light coming from nature into the lens, i.e. the camera, through which an effective focus system works on the ‘background’ of the image and the ‘content’ of the image. The more controlled the aperture during the shooting, the more precise the focus will be on the subject in the image, and the less uncontrolled and open the aperture will be, the less will be the focus on the image.

The larger the aperture, the smaller the number;

The subject of the aperture is specified with. The lower this number, the larger the aperture. In this case, a mathematical calculation works.

Ratio = Focal length / open space

For example, if a 50 mm focal lens is exposed to 10 mm of light, the aperture will be 8/5.

Shutter Speed

One of the most important issues after the aperture is shutter speed. If you want to take pictures of the desired quality, you need to keep a close eye on this issue. Generally speaking, slow shutters usually have blurry images, while very fast shutters can ruin the quality of the picture. Increasing or decreasing the shutter speed is expressed in the language of the camera with "Stops". For example, a 1/30 second exposure will give a clearer picture than a 1/60 second exposure.
