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.
Economy is the mother of most inventions, not necessity, unless in the sense of poverty and hardship. A requirement for convenience is simply a diluted requirement for ease and economy.
It seems to be invariably true that those characteristics which lead people to call a design functional are derived from the requirements of economy and not of use.
