Now let's proceed to analyzing the center of the composition. There is an optical center in the middle - you will notice that the center of the composition, the major element will never be placed there, otherwise the scene will look artificial. The center of the composition will always be the most striking element, and the rest will just serve to make it more expressive. The artist may use various means to achieve this effect - the color contrasts, light and shade effects, size of objects and distance between them. Secondary elements are depicted with less detail and vigor - they have to bring forward the center, not block it. Notice the way your eyes travel the painting - intuitively you will start at the center and will proceed to the rest of the elements to refine the story.
A good interior paint job is often 50% preparation and 50% painting. Do not rush in preparing the surfaces in your eagerness to get at the brush or roller. If you do not prepare the surfaces properly, you'll be back with the paint brush or roller in a few months.

Once you figure out which position is prime and which position is spray, place the valve in the prime position and grab the primer hose. Point the primer hose in the empty bucket near the top and at an aproxx.45 degree angle from the side (the reason for this is that there is likely to be pressure still built up in the airless and when you first switch on the airless to prime it, paint will likely burst out of the primer hose and you don't want to have it go everywhere). Now turn the airless paint sprayer on and you will see that the airless is sucking up the new paint and pumping out the primer hose. At first you will typically see a cleaning solution come out followed by your paint. When you see your paint coming out switch over the primer valve to the other position and you will see the airless pumping paint into the main hose.
