Tracers can be described as the experience of trails of varying lengths and opacity being left behind moving objects in a manner that is similar to those found in long exposure photographs. These can manifest as exactly the same colour of the moving object which is producing it or can sometimes be a seemingly randomly selected colour of their own.
A near consistent way to reproduce this visual effect is to simply move one's hand in front of their face or throw an object under the influence of a moderate dose of psychedelics.
Tracers can be broken down into 4 basic levels of visual intensity. These are defined below as:
- Subtle - The most basic form of tracer can be described as an almost completely transparent after image which disappears quickly and drags shortly behind moving objects.
- Distinct - At this level, tracers increase in their length to become roughly half as long as the distance across the visual field which the object it is following has moved. The clarity of these tracers shifts from barely visible to distinct and partially transparent in colour.
- Intense - At this level, tracers become mostly solid in appearance and almost completely opaque in their colour with increasingly distinct and sharp edges to their shape. This creates a clear contrast between the tracer itself and the background behind it. The tracers become slower to fade from one's vision and can remain in the air for up to several seconds. This results in longer trails covering the entire distance across the visual field which the object creating it has moved.
- All-encompassing - The highest level occurs at the point when a person’s visual field has become so sensitive to the creation of tracers that it entirely smudges and blurs into an all-encompassing tracer at the slightest movement of an object or the eye. This can make it extremely difficult to see unless the eyes are kept still in a motionless environment as tracers linger almost indefinitely or until one looks elsewhere within their visual field.
