The human eye is used to seeing zones. What the eye falls on in the natural state is often zonal. This is a concept better viewed than discussed. It’s just the way things are.

      

    This is important to your website. If you present a picture where the constituents of it are out of zone, this may be artistically interesting and very original, and an artist may find all sorts of reasons to argue that it looks good – but it will still alarm the deep mind and that process is beyond conscious control.

    Zones are among the subtlest of the influences on a website and can be awkward to evaluate. If they’re only marginally incorrect they don’t have a lot of bad influence. Much of how they appear depends on where the light seems to be coming from on the picture presented on the screen, because the general principle in all human activity is that light comes from above and darkness rises from beneath. The website doesn’t have to relay this exactly, but it’s also very important that it shouldn’t break those basic rules. For a fuller explanation of this, see the page on this site devoted to light and dark.

    The concept of zones is also borne out in the human being. As is usual on this planet, because it's driven by the impulse to grow upwards and towards the sun, source of all light, the human body bears the same zonal signs as plants and trees and the horizon, and it broadly follows the same imperatives. As is also common, there’s room for replication inside those zones. Even the face carries the signs of this.
