High Definition Broadcasting

High Definition broadcasting is where TV channels or stations have their programmes running in HD.  This basically means there are more pixels in the frame bringing more colour and more detail on to the screen when you are watching something.

TV stations have been adding HD channels on to their digital programme list where as they are not yet on analog, but in Japan they first brought out a HD broadcast on to analog on June 3rd 1989! As we are able to fit more pixels in to each frame this also means that there are 60 frames per second which is twice the amount of a conventional TV! 

When doing make up for HDTV it is so important that you keep checking your work in the mirror, what you see in the mirror is what people see on the screen. 
I watched a little clip online of a make up artist called John Woodbridge, he explained why doing HD make up is really important - 

John Woodbridge is one of the UK's leading make up artists specialising is HD make up, he is the third of his generation who have became make up artists too. He does a lot of film make up techniques to the cutting edge creativity and cosmetics.
He is well known for his very natural grooming on males and little corrections to the glamorous make up and air brushing skills that he holds.

Most products that you have in your make up kit will be fine to use for HD, you don't always need an air brush machine to create the look.
Make sure you look in the mirror at what you can see and also look at the model too because anything that needs touching up will be made apparent when seen in HD.
Airbrushing is made from micronised pigments, these are much smaller and so they are less visible to see on the skin and they are very lightweight too. You can easily blend out any lines on the skin and it will last much longer than normal products on the skin. If there are any spots that need touching up you can apply a translucent powder on to the skin too.

It isn't just the foundation that you can use airbrushing for, contouring, highlighting and blusher is available for air brushing. John Woodbridge mentioned that blusher is always poorly applied when with a brush, so airbrushing gives a softer effect on the skin and isn't as harsh.

Loose powder is available in an HD form as normal setting powder can make the skin appear dull and ashy which doesn't give the skin a good look when on TV.

 

The same goes for hair stylists too, you need to make sure the hair looks as natural as possible, not too much product on the hair, if the scalp is dry it could be make more clearer as the image on the screen will me clearer too.
Rules of hair dressing any way are to hide grips and anything else in the hair that doesn't need to be seen.
