EAGLE EYE VIEWS
The New York Public Library has a phenomenal cache of commercial photographs taken from just before and after the turn of the last century among their vast digital collection. I have been enjoying them, but have become even more intrigued by what happens when you zoom in on details that you normally would not focus on. Eagle Eye Views is a collection of isolations and captures from this database. I provide a link and ID for each original photo at the NYPL site.
