What attracts me to architecture, and windows specifically, is my love for geometry, lines, shadows, patterns and abstractions, and minimalism. We are all trained to recognize patterns, starting at an early age. Although this learned skill set has more to do with behavioural patterns, it makes sense that we extend this to visual/spatial patterning. Architecture and, particularly, windows are commonly uniform and repetitive. Urban development in places with a high population density typically means vertical development. Architecture is more intimate and less uniform in smaller towns, villages etc. In both cases the window reflects this.
Architecture at its best is determined by function; the purpose of the building is the starting point for form. By extension, the function of windows is to let in light and provide ventilation. They allow a view out from inside a structure, and can act as its skin. Usually they are rectilinear. Their reflective surfaces add another dimension to the structures that house them.
As I look through the camera I try to arrange the elements I want in the frame, compositionally, so that the photo will draw the viewer in. Light quality is as important as subject matter. With these three things in place (light, space/composition, subject matter), I begin to work toward the image I want. What I exclude from the frame is as crucial as what I include. I am interested in details, facades, patterns and abstractions, and what a particular building may represent. Similarly, context often does not matter to me. I try to keep the composition clean to avoid distracting elements; fewer elements can produce a stronger image.
