Imagine this, you're given 4 weeks to take a massive amount of photographs - oh the joy! The subject? Anything and everything that catches your eye, just 4 weeks of speculative play. Nothing is too small or insignificant to be a subject, in fact, you don't have to find meaning or concept, just interesting visuals. 4 weeks. That's a huge number of photos and a massive number of subjects.
Now imagine that rather than use the 4 weeks, you instead decide on a specific subject in 5 minutes. No play, no speculation, no research, not even a single photograph taken, just pin in the map decision making. 5 minutes from 4 weeks. That equates to 0.012% of the time given, the same as making a decision in 0.4 of a second when given an hour.
I don't know about you, but I think taking the whole 4 weeks seems like a much better plan.
