Illustration of an Heath Exchanger
Technical illustration, ISO A1, brownprint.
Perspective.
The huge heath exchanger in the illustration was designed by Navalimpianti for CIRA plasma wind tunnel facility.
The perspective outlines its main features under a moderate wide-angle field of view.
Limits
Qualified perspective treatises consider a field of view about 30° wide as a limit to obtain an undeformed two-points perspective.
Well aware of the use of wide-angle lenses in photography, I began to widen FOV beyond its usual limits to enhance perspective effect.
Illustration above features a 45° FOV, as well as a moderate wide-angle lens.
