During the first workshop I ever attended one assignment we were given was. The class was to shoot an entire roll of film only using one lens of a scene utilizing the full range of the lens and all photographs must contain the same main point of interest.

To this day, every now and zen a shooting session begins and ends this way. Not so much as this lessons objective but more an exercise of contemplation or meditation to refine and define the elements that attracted me to begin with.
Here is a quick example after discovering some wild oats growing along a fence outside my house.
