Historically, albedo features were the very first (and usually only) features to be seen and named on Mars and Mercury. Early classical maps (such as those of Schiaparelli and Antoniadi) showed only albedo features, and it was not until the arrival of space probes that other surface features such as craters could be seen.
On bodies other than Mars and Mercury, an albedo feature is sometimes called a regio.
On bodies with a very thick atmosphere like Venus or Titan, permanent albedo features cannot be seen using ordinary optical telescopes because the surface is not visible, and only clouds and other transient atmospheric phenomena are seen. The Cassini–Huygens probe observed multiple albedo features on Titan after its arrival in Saturn's orbit in 2004.
Today, thanks to space probes, very high-resolution images of surface features on Mars and Mercury are available, and the classical nomenclature based on albedo features has fallen somewhat into disuse. It is even so still used for Earth-based observing of Mars by amateur astronomers.
However, for some Solar System bodies (such as Pluto prior to the New Horizons mission), the best available images show only albedo features. These images were usually taken by the Hubble Space Telescope or by ground-based telescopes using adaptive optics.
Cydonia Mensae on Mars is an example of an albedo feature.
