Next time you're in San Francisco don't miss the awesome, stroller-free Pier 24 Photography.
One of the many pleasures when I visited was the room devoted to Andreas Gursky, including 99 Cents, the magnificent photo you see above. Using digital manipulations I can't begin to understand, Gursky created a vast, impossibly sharp image. I only tore myself away from studying the picture when I became embarrassed at how long I'd spent staring, walking forward and backward.
It seems to me that the consumerist distribution of colored packaging mirrors the egalitarian use of shades in Gerhard Richter's color field paintings, another favorite.
