High-definition Broadcasting

High-definition Broadcasting is a better and clearer than normal standard television broadcasting. What the viewer sees in HD is a much better quality than what is seen from a standard analog television or other TV formats.
As a result of this make up artists have to be more aware of the looks and the work they are creating for camera as everything is more detailed and more obvious in HD. Small things that wouldn't normally be picked up will be very obvious when broadcasted in high definition. For this reason, many makeup brands have created a specific makeup line designed to make the wearer look flawless under HD film and photography. This makeup is made up of micro-fine particles that reflect light in just the right way under a HD lens, leaving the wearer's skin looking unbelievable.
However this is not the only thing makeup artists must consider when working under HD broadcasting; too much makeup is also very obvious under a HD lens, therefore cleansing, toning and moisturising the skin before applying makeup is essential in evening out the hydration of the skin and assisting in applying makeup to look flawless.
As well as HD makeup, makeup artists also use a technique known as 'airbrushing' to create a flawless finish, this consists of micronised pigments that are less obvious on camera. The technique works using a mini compressor that discharges compressed air that leaves the final look to appear lightweight and even. In addition to making the skin look so clear, the airbrushing technique is also easier to blend and doesn't leave lines of makeup.
