I have decided to consolidate the curation— both of my photos and what I see elsewhere— onto a single blog over at Wordpress: Singly.Photo. one of the side benefits is to change Instagram's usage to be more whimsical/social, and any sensible photograph to be posted at Singly.Photo. the Kerteszian series at Instagram will continue.
the image below connects Instagram/Singly.photo and now the end of the work on this page (not site!) to Singly.Photo.
