In a dual action airbrush the trigger controls both the air flow and the paint flow. Beginners should really take the time to practice on how the trigger works so that they can perfect their ability to airbrush. Your airbrush will have a back lever as well that acts to shut off the air flow and paint flow when the trigger is released. A couple of great features of the video is that you will learn how to truly work with House of Kolors paints and how to work with low air pressures. Learn more about how to do freehand is also a great asset of this video. These are advanced techniques and will take you as an artist to the next level of airbrush art. If you are at an intermediate level with airbrush art then The Ultimate Airbrush Handbook by Pamela Shanteau is for you.

Airbrushing nails to airbrushing cars is explained in great detail to help you advance further no matter what surface you like to put your airbrush art on. In the UK airbrush art workshops are being offered by Organic Image with instructor Beej Curtis. Beej Curtis instructs on airbrush art in 1 and 2 day classes covering different aspects of airbrush art. Beej Curtis also offers private 1 on 1 lessons for anyone wanting to learn in a more private setting. To do airbrush art on nails you will need nail art stencils or nail art masks. The nail art masks are reusable masks that have an adhesive that does not leave any residue on the nails. Of course if you are really creative and very good you can freehand the airbrush art right onto the nails. If not then take the time and invest in nail art stencils and masks. Now that you are ready to begin airbrushing the tattoo on, you need to take your time and be careful of what you are doing. There are no rooms for mistakes with airbrushing on a person's skin. So take your time to ensure you don't make a mistake on a person's body with the airbrush paint. While experienced artists understand this, again a beginner may not.
