You are looking east from the Tibidabo Panoramic Area , located 1,680' (512m) above northeastern Barcelona.
I scanned this skyline while my 20-month-old son was strapped to my chest. The only way I could possibly accomplish this four-minute panorama without his youthful flailing overpowering my camera's image stabilization was by distracting him with a delicious cookie, which he later dropped on the ground.

To create this image, I used the following tools:
- PTGui Pro 13.1 for stitching the panorama
- Photoshop to content-aware fill a small area in the output panorama I missed while scanning
- ImageMagick to convert the
.psbfile from Photoshop into a PNG file.- Photoshop can't export TIF files larger than 4GB, so I saved the edited image as a 5.56GB .psb, then converted that into a 2.58GB PNG
libvips to create the image pyramid from the full-resolution panorama:
vips.exe dzsave pano.tif outfolder --tile-size 512 --suffix .avif[Q=69]- OpenSeadragon to create the above image viewer
