Pixels are the smallest unit of an image. The word Pixel is derived from the English word Picture and element. When we see an image on the digital platform, it is actually a collection of pixels that are decomposed into bytes of this image. Everything we see on our monitors has a pixel count.

When we do something from the computer, we generally use LCD monitors, these monitors are actually pixel-based, and there are dots inside our monitor. Each pixel consists of three dots, also known as RGB colors. Red (Red) Green (Green) Blue (Blue) colors are the combination of these colors with each other, a color emerges.

Each color can take 255 different values, each value is called a 'bit'. For example, if we say R:255 G:255 B:255, we get the white color, or if we say R:0 G:0 B:0, we get the black color. The smaller the size and number of pixels in an image, the greater the sharpness and clarity of the image.

Pixel Adjustment

Changing the pixel dimensions of an image not only changes its size on the screen, but also changes the image quality and printed properties. Therefore, it is a situation that requires a lot of attention.

There is a wide variety of programs available to change the pixel dimensions of an image. But let's talk about how you can do this on Photoshop, which is the most widely used program:

 - Choose Image > Image Size.

 - Select Keep Proportions to keep the current ratio of pixel width and pixel height. This option automatically updates the height when you change the width.

 - Under Pixel Dimensions, enter the Width and Height values. Select Percentage as the unit of measure to enter values as a percentage of the current dimension. The new file size        of the image is displayed at the top of the Image Size dialog box, with the old file size in parentheses. 

 - Make sure Resample Image is selected and choose an interpolation method.

 - If your image has styles applied, select Scale Styles to scale the effects on the resized image. This option is only available if Keep Proportions is selected.

 - Click OK when you're done setting the options.

Pixel Test

While obtaining an image as a result of the combination of millions of pixels and various colors on devices with a screen; Some of the pixels on our screen can become dysfunctional, sometimes due to factory errors and sometimes due to user errors. Pixels that have lost their function are called "Dead Pixels".
