Aspect Ratio

Image
What is Aspect Ration? The height and width on an image is referred to as the aspect ratio. It defines its overall shape, and it is usually shown as W:H where W is width and H is height. The most common aspect ratio today is 16:9, which means that if the width is divided into 16 equal parts, the height of the TV or picture should be 9 parts.   16:9 works great for TVs since that is the format modern TV shows are delivered on, but most movies are made using the cinema standard, which is 21:9. 21:9 is much wider, so parts of the screen need to be filled with black bars above and below the image in order to fit most TVs. These horizontal bars are called ''letterboxes''. Similar to movies, TV shows used to be made using a 4:3 aspect ratio, which is a lot more square than current TVs(this is why 16:9 is often called a widescreen aspect ratio). To fit modern TVs, vertical black bars or 'pillarboxing' is used. We've listed the most common aspect ratios in the t...

Quarantine affecting different people

Image
Covid-19 itself has a huge impact on everyone psychologically, but quarantine has an impact on everyone differently according to their personalities. But mostly, it affected people badly in different ways, especially financially. Many people lost their jobs and source of income.   When quarantine began, it looked like it is heaven for all the introverts out there yet extremely difficult for extroverts. Introverts are people who do not like to socialize a lot. For them, quarantine was like a dream coming to reality because they do not have to socialize much and prefers to spend time alone or with some people whom they know intimately. Introverts in quarantine are more energized than ever. Being introverted does not mean you do not like people, it means you just do not like to talk because it just means that doing it de-energizes you. They get moody and irritated when they do not get enough alone time. So quarantine was a great advantage for introverts to get away from crowds and int...
