Architecture is all about form. Therefore, it is easy to get lost in the different shapes and lines that make up the structure. For this reason, it is important to choose a feature that is simple in form, and has strong lines and shapes.
In addition to this, the colours may sometimes distract you from noticing certain aspects of the building. But by converting the image to B&W, you will notice how your eyes move around the frame, noticing the different lines and forms in the photograph.
