It's pretty subjective. For me, it's an exercise in taking the time to observe situations which are fleeting, or easily overlooked, with an emphasis on those which I found pleasing, or which made me stop and ponder for a moment. And it's probably best that there is no universally agreed-upon definition of "cool" because that would be, uh, uncool, as it would leave little room for surprise and discovery.
I started taking photos of my meals simply as a way of remembering what I had been doing. But at some point realized that if I put a little more effort into reducing surrounding clutter and finding the best possible light, the result was way more memorable than if I had simply grabbed the nearest available seat and started slurping my soup.
Arrangements of stuff (top center) had been vaguely on my mind for some time, inspired in part by the "idea board" trend, the discarded-items photos of
Hong Hao and the supermarket scenes by
Andreas Gursky. Mine are arrangements of everyday items, but they also serve as a snapshot of what was on my mind at the time.
