Pixel aspect ratio refers to the ratio of the width to the height of a pixel. It is essential to ensure proper display and aspect ratio of images or videos on different devices or screens. For example, standard-definition television (SDTV) uses a pixel aspect ratio of 4:3, while high-de...
A physical pixel on the focal plane of a sensor absorbs photons that become an electrical charge. That charge is converted to a number and placed into an array, or raster format. Because the position and altitude of the sensor at the exact moment of exposure is precisely known, the pixel'...

As we touched on earlier, pixel density is a key component to ensuring your image is as crisp as possible, giving it that high-resolution, polished look. However, a high pixel density combined with the overall size of the image itself will increase the image’s file size, which could nega...
What is high definition (HD)? HD refers to a video resolution with a higher pixel count than standard definition (SD). HD videos have a minimum resolution of 1280x720 pixels, commonly known as 720p, but can also have a resolution of 1920x1080 pixels, also known as 1080p. This increase...
What does pixel density and pixels per inch (PPI) mean? Here's everything you need to know so you can make the best possible buying decision.
How many pixels per inch is 1920x1080? A display or image of 1920x1080 pixels is 1080p resolution – commonly known as ‘high definition’. To work out PPI, you’d also need the diagonal measure of the screen or image in inches. Pixel count can then be divided by the number of inch...
A tracking pixel is also called a marketing pixel, or a web tracking pixel.The tracking pixel code contains an external link to the pixel server. When a user visits a website or opens an email having the HTTP tracking pixel, the HTML code is processed by the user’s browser, which ...
Resolution is a term that tells you just how densely these tiny dots, the pixels, are put together on the display. Individual pixels collect together to make up the image you see on the screen, so the higher the pixel count the higher the resolution. The "K" in 4K stands for Kilo (...
