I realize this isn't news, but a recent event reminded me of the constant evolution and downward price pressure of technology. I found a CD of images of my grandfather's general store in southern Illinois (Edwardsville, outside St. Louis), and I transferred them to my backup disk. What was remarkable was that the images were on the CD because they took up so much room on my hard disk circa 1996 that I desperately needed to get them onto some removable media. I remember thinking how enormous and high-res the images were (they were negative scans), but as I was putting them onto my (now insanely cheap and huge) backup drive, I noticed that the file sizes were only around 1.2MB. I routinely create, download, and move around over wireless networks files of that size without giving a second thought. The images themselves are pretty remarkable and reflect another era - 1972 small-town America. They are significant to me also because this was how I saw the United States as a very young ex-pat living in London, England. I lived overseas until I was about 10, and on our occasional trips back to the States, we would visit the store. I remember fondly hanging out in the store reading comics and being spoiled by my grandparents with American candy and A&W root beer (from the actual shop in jugs!). This is what I thought the rest of America was like.
It doesn't look so huge in this photo, but walking across the Brooklyn Bridge this morning I snapped a photo of something I've seen before - one of those massive cruiseships docked in Brooklyn. It just looks so out of scale. I remember seeing one docked in St. John, USVI. It completely warped my sense of how big the islands were.
