High Definition Broadcasting

What is High Definition?

High Definition Broadcasting was first introduced in the late 1980's. High definition is a video or mage of a high quality and resolution. There are normally two formats of this.

  • 720p(1280x720) 16:9 ratio
  • 1080p(1920x1080) 16:9 ratio

The 1080p resolution is higher than the 720p resolution. This is because it has more pixels and picks up even the slightest details that are shown on television. 

Television channels of today that broadcast in HD are, BBC1 HD, ITV2 HD, ITV1 HD and many other sky channels. High definition is also widely used in the film industry as well. 


High Definition and Make-Up
In the video on the right, make-up artist John Woodbridge explains and shows how make-up artists and the make-up itself are affected by high definition. He believes that too much make-up can appear really obvious on HD. This is because it catches the slightest details and will pick on any imperfections in the make-up.

As the make-up has to appear really natural and it should look like the model's have none on, airbrushing is a really good technique for film and tv. This gives a really flawless and natural finish and doesn't leave too much product on the skin.

A traditional setting powder can often be a problematic product for HD cameras, according to Woodbridge. This is because the non-micronized powders can give the skin a very dry and ashy look on camera. Special HD powders a better to use when filming with HD cameras.
