The reason it's better for photography and video production is that it's applied in a dot pattern, similar to the way digital photography and high definition video capture and reproduce images. This is not only a benefit to makeup artists, photographers, models and actors. There are many times when non-professionals need high quality makeup and photography, such as for business, wedding photographs and prom.
If you're a non-professional, you can find airbrush makeup kits in a variety of high end beauty supply stores and online. Applying the makeup is easy, with a little practice. The most common use of airbrush makeup is foundation and blush, though it's used for eyeshadow, lips and eyebrows. Foundation should first be tested on a blank sheet of white paper to check the coverage and control of the spray. Shake the foundation bottle before filling the applicator to remove any air bubbles that will disrupt the flow. Apply the makeup in a circular motion, beginning at the forehead, and overlap each layer slightly. Continue application until you have the level of coverage you desire.
