File:Retina zoom comparison.gif

Summary

The central city of Frankfurt am Main with the shopping street "Zeil".

Animated comparison of http://mc.bbbike.org/mc/?lon=9.97052&lat=49.97859&zoom=15&num=1&mt0=mapnik-retina . Frames:

1. default (same appearance as standard (non-retina tiles)
2. used Mozilla Firefox' zoom feature (not text only) to enlarge the map. Set slippy map zoom level to such a level that the map's coverage is equal to before. See Disabilities#Using_ordinary_online_maps_with_visual_impairment.

Made with screenshots and GIMP.

File:Retina zoom side-by-side comparison.png is a similar comparison image, but static side-by-side, covering a smaller area of the same city
