When painting smooth ceilings, the best strategy is to roll parallel with the main source of natural light, such as a big window, as it helps prevent roller lines. If you roll perpendicular to the dominant light source, the roller lines can form a slight shadow. The same applies when spraying.
Always perpendicular to the wall with the light source (in your example, you paint from wall A to further away). You do this in case your coats are not even, the light will reduce the imperfections instead of casting a shadow at each roll pass.
The ceiling joists usually run perpendicular to the rafters or the primary load-bearing beams of the structure. This direction ensures optimal weight distribution and structural integrity.
Paint in a 'W' motion to ensure an even distribution across your wall.

Roll vertical strokes from bottom to top, stopping short of the ceiling. Then roll back down again.
Hanging drywall perpendicular to the overhead framing members is a good idea for several reasons: Less visible Seams – A perpendicular orientation allows each sheet of drywall to float over the framing members, making uneven joists or trusses blend in.
Wood floors should always be laid perpendicular to floor joists—across rather that in between them. This will make the floors structurally sound and will help prevent the planks from separating, sagging or buckling.
Not Fully Loading the Roller
The roller needs to be fully loaded with paint to the core, otherwise you'll get air bubbles on your wall, resulting in “paint acne.” To avoid this mistake, roll back and forth on the roller tray until all bubbles are gone and the roller feels heavy.
Many painters “break in” a roller cover by priming it with water or thinner. In our lab we never prewet a cover before painting. If you choose to, you must spin it out with five or six strong pumps so it is only lightly damp. Then take even more moisture out by blotting the cover with a paper towel.
Start with the ceiling
We recommend you start your decorating project at the top and work your way down. Taking this approach will allow you to avoid dripping any paint onto freshly painted areas. Before you start painting, clean your ceiling, fill any holes or cracks and sand it.
Work section by section laying off each section by moving the roller in long parallel strokes while the paint is still wet. This helps avoid passing the roller over paint that's already started to dry and leaving noticeable edges.
In most buildings, structural beams run across the shortest length of ceiling because that enables them to support the most amount of weight. This is safe bet for most people installing faux – especially on flat ceilings. If you're installing beams on a sloping or apex ceiling, you could run them either way.
Joists can be located by either tapping across the ceiling with a knuckle or with an electronic stud finder. With a knuckle you tap across until a more solid sound is heard – this is a joist or beam. A hollow sound is the space between the joists.
The typical range for ceiling beam spacing is anywhere between two feet apart from one another up to eight feet apart. The most common ceiling beam spacing is four feet apart. Shorter spacing will give your ceiling an attractive patterned look, creating a real focal point.
If you roll perpendicular to that source of natural light, you may see a shadow where your roller lines are because the light will be coming right across them. On textured ceilings, the direction you're rolling probably won't make a big difference as long as you're doing a nice, neat job rolling.
Does it matter which way you hang drywall? Hanging drywall can be done both vertically and horizontally. This entirely depends upon the fire codes and regulations in your location. For instance, many commercial buildings require drywall to be installed vertically.
Adding glue won't increase the strength of the drywall, and it can make it much harder for you to remove and replace damaged drywall. Adhesive can bridge gaps, though, and it can keep temperature-controlled air from escaping or entering through the ceilings, making rooms more energy efficient.
It is common for an artist to turn a painting upside down during art creation. It can be used to apply different techniques or just to get a different perspective as the painting is established. In abstraction, it is customary to turn the paintings around least ten times before completion.
