SETTING THINGS STRAIGHT
By MICHAEL PERKINS
ONE OF THE MOST ELUSIVE EFFECTS IN ARCHITECTURAL PHOTOGRAPHY would seem to be the one most easily achieved: the look of a straight line, the foundation upon which an orderly image is built. However, the human eye is often more unreliable than assumed when it comes to reading and identifying that which is supposed to be “straight.”
We’ve all been confounded by optical illusions that present lines that are not, objectively, straight at all, even though our brains, based on our interpretation of the visual data, say they must be. However, we tend to dismiss this sensation as trickery, something we don’t have to sweat about in making a “real” picture. And that is probably a mistake.
Based on what kind of architectural design you’re shooting, what lens you choose, even where you stand, a straight line, either horizontal or vertical, can seem to bend or lean, making our “factual” images less than trustworthy.
Even setting up a shot on a carefully calibrated tripod and a bubble level can produce a result that looks as if it was manipulated. Of course, based on what look you desire, you may regard geometric reality as irrelevant, and deliberately engineer ” unreality” into a photograph. That’s why we make a distinction between taking a picture and making one.
As an example, the picture seen above was taken super-wide, at 18mm, to intentionally exaggerate the size of the room, making some verticals bow in while others register normally, and playing stretchy with the ceiling arches and floor horizon. The idea here was to distort the already extreme Art Deco accents and give them an extra funhouse quality. Shooting with a more conventional focal length like 35 or 50 mm would have made for straighter lines, but would also have sacrificed every other effect achieved at 18mm.
Bottom (straight or crooked) line: dimensions and angles are suggestions, not commandments. But it’s a lot easier to break rules creatively once you understand how they work.
