What is high definition broadcasting and how it affects hair and makeup artists.

High definition (HD) broadcasting began in 2006 in United Kingdom and it displays high definition displays and quality. It affects make up and hair artists a lot because the quality on the TV are more high standard than before and the audience can see the details of people on the TV more clearly. For example when the camera zooms in, you can see the close up of the makeup and hair styling of the person on TV. It is very important that for makeup artist to understand how lighting works and how it affects the makeup look on TV or film as it might be different to what you see in person. 
It is a problem for makeup and hair artists as if the makeup isn't up to scratch it will be visible on tv and will make the makeup artist look unprofessional. Also with the hair artists if there are any stray hairs or if the hair doesn't look right whoever is watching will see what's wrong with it which will look bad on the artist. Also the tv show or film wont be taken seriously which is something they would want to avoid.
