Design & build
Northlight
The observatory had twenty years of photographs on a network drive and a spreadsheet describing them. We turned the drive into the content folder.
The interesting constraint
Every image had to load fast on a phone in a field with one bar of signal. Counterglow generates renditions on first request and caches them as static files, so the second visitor never touches PHP at all.
