Explaining and suggesting often cause a dilemma. There are a lot of examples of competitions in which the winner barely performs images. The project’s author trusts the jury will understand, just with the planimetry, the interest of his project, its essence.
In other cases, a single image is performed, two at most, to convey the essentials of the project. In fact, few buildings “endure” being brilliantly photographed from multiple viewpoints. I said convey and I did it intentionally.
Because, finally, the third aptitude in relation to representation, is to explain. The building may have a certain complexity and the author does not trust the spatial skills of the jury in understanding the proposal. Therefore, multiple viewpoints are shown. There is little chance for imagination to draw conclusions.
As usual, the balance will find the right answer.
