It took me a little while to come up with something for this week’s challenge about dialogue between pictures. I sorted through hundreds of photos before finding a commonality – and difference – between the subjects. The first photo was taken at Yerba Buena Gardens in downtown San Francisco, California. The second was taken at Pua’a Ka’a State Park in Maui, Hawaii. Both depict waterfalls, but one is man-made, while the other is natural. Which do you prefer? Can you appreciate both equally? Think about it.
