1 Simultaneous Contrast

Simultaneous Contrasts Wikipedia Image

We perceive things by different sensorial faculties and against many diverse contexts. In addition we perceive things and happenings in time and space scale. Whenever some details are required, the other senses fill-up the specifics. Typically our bilateral faculties like eyes and ears continuously back up the space position details. Similarly multilateral nodes of touch also support such a process.

Space position or time marking details are affected by the quality of context. Where the context is dulled or rapidly changing the particulars of things and happenings fail to register effectively. The ‘back or fore’ grounds offer a scale to size-up the perception, and also format relationships in terms of now-then, here-there, far-near, etc. The time factor operates as ‘Concurrent and Sequential contrasts. These two aspects are affected by our past experiences and expectations (desires). The aberrations of perception arise from here. The way colours are seen or weights are felt is due to such contrasts. Our past experience and desires make us see or experience things before they happen at closer locations.

Contrast

Contrast or contextual effects created or employed in our daily life, are in home arrangements, food menus, dressing, expression and communication, etc. We create visual emphasis by accentuation of colour, illumination, texture, patterns, surface exposure duration and extent, etc. We generate audio accents by sound pitch, pressure, time gaping, replaying in different frequencies, etc. Touch experience is controlled by proximity, duration, exposure of body-limbs, extent and additional information such as temperature (warmth-cold), moisture, breeze, etc.

The contrast effects can be attuned by manipulating the time and space fields. TV programmes often separate out the interviewer and interviewee in time separated frames, within same frame by superior-inferior positioning, or by comparative sizing. Additional information such as audio-video clips can break the relationship developing between the two time and space consecutive items. In a formal party tea, coffee or pre-post dinner drinks are served in different rooms-ambience.

Contrasts occur within same reference of framing. Such contrasts are of position, orientation, scale or direction. Contrasts also occur as reference to an experience (of the past), which are intense or diffused, fragmented or converged with many others. There is no physical presence of framing. In the first case, the contrasts are framed objects and dealt (stored, manipulated, re-expressed or communicated) accordingly. But in the second case, the contrasts are transient, and if one tries to manage these by way of storage, expression or communication, it becomes a new subjective interpretation.
