Nails should be clean and buffed prior to beginning. Buffing the nails will give for a rougher surface for the paint to cling onto. Prior to actually airbrushing the nails, a base coat should be applied. There are actually two reasons for the base coat. This base coat will help protect the nail from the paint and help the paint to adhere to the nail better. Working with an expert can also mean signing up for some private one on one lessons that will give you more direct attention from the instructor. This could give you a little bit more of an edge over taking a work shop where the instructor has many people to teach at one time. Once you have mastered your skills in micro airbrush art you will be amazed at the amount of detail that you can place in any airbrushing project. The experts showing you how to do something on a video make it look so easy. You will believe it is easy until you get out there and try to do it yourself. It is at this moment that you realize that you are not able to do what they did. To start with you need to practice with simple techniques until you get the hang of how to do them. A damages needle can be disastrous to your ability to create high quality art, because if you are unable to straighten a bent needle back out or the needle should break completely you will not be able to finish your airbrush art until you can get a replacement. If you do end up bending your needle you can try and straighten it with either pliers. The application of makeup takes time and a lot of practice to be able to do perfectly. The human face is one canvas where an artist does not want to mess up. One must be sure of their abilities with not only the application of the right makeup but also with use of an airbrush to apply those makeups. Those that apply make up are considered artists and airbrushing on makeup is just another great way that they have found to show off their artistic median. This feed is great for airbrush art designs that call for fine detail as the gravity feed uses less air pressure. The less air pressure means that you can use slower movements when airbrushing. The bottom feed is where the cup is mounted to the bottom of the airbrush and the paint is brought up via a siphon tube.
