I learned years ago how important it is to shoot the same subject and location over and over again.
The practice teaches a photographer how to form deeper relationships with the subject, and better understand how the primary subject interacts with secondary elements – like the way high tide may introduce a stunning new reflection, or how a blaze of stars in a dark sky might be the missing element that lifts the image to new heights.
Revisiting a subject also serves as valuable “practice.” You cannot develop your skills in anything without a healthy (or obsessive) amount of practice. It always surprises me to find out aspiring photographers think that they can simply photograph their two-week vacations once or twice a year and come home with compelling imagery! It doesn’t work that way.
Run a single loop measuring 4.16667 miles within a single hour. Now do it again. And again. Now keep doing it – starting a new loop on the hour, regardless of how fast you finish the previous one – until there’s only one runner willing or capable of doing so. Welcome to the simple – some might say sadistic – concept of the Big Dog Backyard Ultra in Bedford County, Tennessee.
I refer to small money-earning business that consist of the work of a visible individual, or have evolved from a personal hobby or skill, as "small economies". We can include in this category newer forms of at-home work—side businesses, telecommuting and the like. The amount of income is unimportant; meager profits are compensated for by the motivation of the owner. A small economy may or may not be someone's main form of livelihood, but it is always a spontaneously conceived and continuing activity.
