Understanding Pixel and Resolution on digital photography

Have you understood the pixels and resolution of digital photos? Or do you only know a little about it? For friends who love photography, you are already familiar with this term. However, it is not uncommon for you to know the term only without understanding these pixels and resolutions.

Pixels and resolution cannot be separated from the world of photography. These two terms can be the main factors determining the quality of a photo or image. Well, to better understand pixels and resolution, this time, we will describe it fully.

Understanding pixels and resolution for photography are very important. The reason, this can be useful to be able to produce photos with good quality and perfect. Pixels and resolution are also important to understand so that you can distinguish between image quality. Well, just for more details about understanding pixels and resolution, see the description below!

Definition of Pixels

First, we will explain the meaning of Pixel and Megapixel. Pixel (Pixel) stands for Picture Elements and is defined as the millions of tiny dots that make up a digital photo. Each Pixel carries information that determines the colour (hue), the strength of the colour (saturation), and how bright the colour is displayed (brightness).

Almost all photos are made up of millions of pixels, where one megapixel is one million pixels. If we look, we cannot recognize a pixel separately and what we see is only a single whole photo with subtle gradations between dark and light, colour shifts, and tones.

In addition to knowing the meaning of Pixel, you can also see pixels by resizing the image size. For example, if you have a photo resolution of 600 x 450 pixels, which is fairly small pixel size, then you can't see a pixel with the naked eye because everything looks smooth.

However, by changing the photo's resolution to a size of 100 x 75 pixels, you can already know what pixels are and how pixels make up the photo. Especially if you try to choose a lower resolution, say 40 x 30 pixels, you can see each pixel grid that looks like a puzzle arrangement to see Pixel by Pixel. The phenomenon where you can see Pixel by Pixel that composes the photo is known as pixelate.

Definition of Resolution

If you want to know the digital image's resolution, then you can look at the pixel size. Because the resolution of a digital image is measured in pixels per inch (ppi – inch device pixels) and the standard resolution for photo quality is 300 ppi.

So, if you want to know how many megapixels a digital camera has, you can find out the optimal print size for the photos that the camera produces. For example, we assume a digital camera with a resolution of 6 Megapixels (MP), with a length of 2816 pixels and a width of 2112 pixels, then the total resolution is 6 MP. So far, have you been able to understand the meaning of resolution?

To calculate the optimum print size that cameras usually produce, you can divide it, which is 2816 x 2112 pixels divided by 300 ppi and the result is 9.5 and 7 inches. So it can be concluded that a digital camera with a resolution of 6 MP can produce photo prints with a size of 9.5 x 7 inches or 24 x 18 cm.

For monitor screens, the standards used are 72 ppi (Windows) and 96 ppi (Mac), so the actual display on the monitor screen is still far from the standard resolution for print (300 ppi). In this case, the definition of resolution means that a photo that still looks good on the monitor is not necessarily as good as when printed.

However, a photo that starts to look pixelated when printed at 300 ppi may appear smooth on a computer monitor. In general, the current average digital camera, starting to approach 24 megapixels as a standard resolution, will have print capabilities that are much greater than the average user's needs.

However, the megapixel size of a camera is not the most important factor when buying a camera. By understanding pixels and resolution then we know about the size and quality of images or photos.
