Are Your Photos Really in HD?

Point, Shoot and Click!! It’s that simple to take a snap with a camera. Almost anywhere you go today, you are surrounded by advertisements of camera phones claiming to give you High Definition or HD QUALITY pictures and videos that you can upload on free social networking sites in India or anywhere else.
But do you really know what HD is? Can you really tell the difference between what is HD and what is not? Or is it all this just a marketing gimmick?
Well, this guide will definitely help you understand the concept of HD in a simple manner that will help you identify your images and videos just like an expert.
What Is HD?
  • It refers to the level of detail in an image on a digital screen. There are some invisible lines per square area that create sharpness or detail which is also called the ‘’RESOLUTION’’. These are made up of very tiny ‘PIXELS’ which together make one frame of an image or video.

  • So, to view images with such sharpness you need to have a TV or smart phone which is capable of handling HD resolution and that can scan the invisible lines of resolution either with Progressive Scan (P) or Interlaced Scan (i)

HD follows up with the Standard Resolution (SD) of broadcast technology and can be divided into two basic categories:
720p HD |1080p HD

Why Different Types of HD?
Now, this might initially sound confusing but it’s not really tough to understand. The term “HD Ready,” when used to describe a television or monitor, refers to a 720p image resolution. The term “HD” may also be used. A 720p image resolution contains 720 lines of pixels along the vertical axis, and 1,280 lines of pixels along the horizontal axis. So, the image is 720 pixels in height and 1280 pixels in width. And, if you are good atmaths you must have already calculated a total of 921,600 pixels. This is the minimum criteria for an image to be recognized as ‘’high definition’’


The difference between HD Ready (or HD) and Full HD can be seen below:
  • HD: 720p image resolution (1,280 x 720 pixels – almost 1 million total pixels)
  • Full HD: 1080p image resolution (1,920 x 1,080 pixels – almost 2 million total pixels)
Therefore, the more pixels there are in an image, the better.
Other Advantages of Full HD include:
  • This means complete digitization
  • It also means files with higher bandwidth and better quality
  • It includes better color sampling and frequency as well
  • Upon viewing Full HD desktop wallpapers or images on your mobile phones, they would appear in widescreen format with a ratio of 16:9
